Why GAO Did This Study: 

The marine transportation system is a critical part of the nation’s 
infrastructure. To facilitate the safety and efficiency of this system, 
the Coast Guard maintains aids-to-navigation (ATON), such as buoys and 
beacons, and conducts domestic icebreaking in the Great Lakes, St. 
Lawrence Seaway, and northeast coast. To conduct these missions, the 
Coast Guard has a fleet of more than 200 vessels, ranging from 225-foot 
seagoing buoy tenders and 140-foot domestic icebreakers to 21-foot 
boats. After the terrorist attacks of September 11, 2001, many of these 
assets took on additional responsibilities for security patrols and 
other homeland security duties. Although some assets have been recently 
acquired, many others are reaching or have exceeded their design 
service lives, raising concerns about how well and for how much longer 
these older assets may be able to carry out their missions. In 
response, GAO examined (1) recent trends in the amount of time these 
assets have spent performing missions; (2) asset condition and its 
effect on mission performance; and (3) the actions taken by the Coast 
Guard to continue to achieve the missions of these assets. To conduct 
this work, GAO reviewed Coast Guard documents, interviewed Coast Guard 
officials, and made site visits to various locations around the 
country. In commenting on a draft of this report, the Coast Guard 
provided technical comments, which were incorporated as appropriate. 

What GAO Found: 

Many ATON vessels and domestic icebreakers have operated more hours in 
recent years than in previous years, with the increase coming mainly in 
homeland security missions. Domestic icebreakers are now used more for 
homeland security than for icebreaking, reflecting their availability 
at times of the year when no icebreaking is needed. While not designed 
for homeland security, the assets can perform such duties acceptably, 
according to the Coast Guard. Most ATON vessels are used primarily for 
ATON activities. Newer ATON assets receive the greatest use on other 
missions, reflecting their greater multi-mission capabilities. 

Trends are mixed with regard to asset condition and mission 
performance. Available evidence, such as the amount of maintenance 
conducted, suggests condition is declining for some assets, though not 
precipitously. Coast Guard officials said some assets, while being 
operated for more hours, are still largely being operated within 
planned limits. Against this backdrop, indicators for measuring 
performance show mixed results: some have declined, while others have 
not. The current measure for asset condition is not clearly linked to 
mission performance, but the Coast Guard is working on developing a 
measure that links the two. 

Actions the Coast Guard has taken to continue to achieve the missions 
of these assets include revising maintenance approaches and developing 
a new analytical tool for deciding which projects provide the most 
capability for the dollars invested. The Coast Guard continues to 
acquire some new vessels to replace aging ones, but proposals to 
rehabilitate or replace other aging vessels have not been implemented, 
largely because of other funding priorities. The Coast Guard also 
studied the feasibility of contracting out some activities. While some 
possibilities for outsourcing were identified in the study, the Coast 
Guard has identified potential disadvantages to outsourcing these 
activities.

United States Senate: 

The marine transportation system, which allows for the transportation 
of people and goods on the water, is a vast and critical part of the 
nation's infrastructure. The system includes coastal ports and shipping 
channels; 25,000 miles of navigable inland and coastal channels and 
waterways like the Mississippi, St. Lawrence, Columbia and Snake 
rivers; and shipping on the Great Lakes. Ninety-five percent of the 
United States' overseas trade tonnage moves by water, and the cargo 
moving through the U.S. marine transportation system contributes 
hundreds of billions of dollars to the U.S. gross domestic product. 
This system also enables the swift mobilization and supply of America's 
military as well as providing recreational value to millions of 
boaters, fishermen, and cruise passengers. 

The Coast Guard is responsible for, among other things, providing a 
safe, efficient, and navigable waterway system, and it carries out this 
role through its aids-to-navigation (ATON) and domestic icebreaking 
missions. In its ATON mission, the Coast Guard establishes and 
maintains over 53,000 navigational aids, such as buoys and beacons, to 
assist mariners and prevent disasters, collisions, or wrecks. To carry 
out this mission, the Coast Guard uses a diverse fleet of more than 200 
vessels ranging from 225-foot buoy tenders to 21-foot boats that can be 
transported on trailers by truck. In its domestic icebreaking mission, 
the Coast Guard breaks ice in the Great Lakes, the St. Lawrence Seaway, 
and the northeast U.S. coast.[Footnote 1] This activity is intended to 
facilitate navigation for commerce, conduct search and rescue missions, 
and prevent flooding. To carry out this mission, the Coast Guard 
largely relies on 11 65-foot and 9 140-foot icebreaking 
cutters.[Footnote 2] 

While some of these vessels have come on line in the past few years, 
many are old and are reaching or have exceeded their designed service 
lives. Their age has raised concerns within the Coast Guard as to how 
well and for how much longer they will be able to carry out their 
missions. In addition, after the terrorist attacks of September 11, 
2001, many ATON and icebreaking vessels took on additional 
responsibilities for security patrols and other homeland security 
activities. In this context, this report examines (1) the recent trends 
in the amount of time ATON and domestic icebreaking assets have spent 
performing various missions and the impact of these trends on their 
primary missions; (2) the condition of the ATON and domestic 
icebreaking assets and the impact of their condition on performing 
their primary missions; and (3) the actions the Coast Guard has taken 
to continue to achieve the missions of its ATON and domestic 
icebreaking assets. 

To address the first two objectives, we analyzed a variety of Coast 
Guard data and records, focusing on fiscal years 2001 through 2005. We 
also made site visits to assets located on the West and East Coasts, 
Gulf Coast, Great Lakes, and inland rivers and met with the assets' 
crews to obtain their views on the condition of their assets. These 
assets were selected to provide diversity in terms of type, age of 
asset, and geographic location. To address the third objective, we met 
with Coast Guard officials at headquarters to discuss recent 
acquisitions and specific management actions they have taken or are in 
the process of taking. We also obtained and reviewed information and 
documents on the Coast Guard's plans to rehabilitate or replace the 
assets or study outsourcing to carry out missions. More details on our 
scope and methodology can be found in appendix I of this report. We 
conducted our work between July 2005 and August 2006 in accordance with 
generally accepted government auditing standards. 

Results in Brief: 

Many of the Coast Guard's ATON vessels and domestic icebreakers saw a 
sharp increase in use for homeland security missions after the attacks 
of September 11, 2001, and while this trend has moderated somewhat, the 
use of some assets in these missions continues well above pre-September 
11 levels. This increase was most prominent for domestic icebreakers, 
which continue to be used more for homeland security than for 
icebreaking. Rather than being diverted from icebreaking activities 
when needed for this mission, these icebreakers are basically being 
operated more extensively at other times of the year when no 
icebreaking needs to be done. In some cases, this more extensive use 
has caused some assets to be operated at levels exceeding the 
recommended levels. Coast Guard officials said that while these 
icebreakers are not specifically designed for security patrols and 
other homeland security activities, they can perform such duties 
acceptably, though at less than optimal levels. In contrast to the 
icebreakers, most ATON vessels continue to be used primarily for ATON 
activities, reflecting the greater year-round nature of ATON activity. 
ATON vessels have devoted additional hours to other missions and this 
reflects primarily an overall increase in the number of hours the ATON 
vessels are used, especially the larger assets. Newer ATON vessels, 
which generally have greater multiple-mission capabilities than older 
ATON vessels, tend to be the ATON assets used the most for other 
missions. 

Available evidence shows mixed trends with regard to both the condition 
of these assets and the impact this condition has on the Coast Guard's 
ability to perform its ATON and domestic icebreaking missions. The 
Coast Guard's current measure of a vessel's condition-- the percentage 
of time it is free of major casualties--is inadequate to link the 
assets' condition to any degradation in mission capabilities or 
performance and, therefore, may reflect a more positive condition. The 
Coast Guard is currently working on a new measure that should better 
link condition with mission degradation. Other evidence, such as the 
amount of maintenance conducted and anecdotal evidence we gathered, 
suggests that as these assets continue to age, their condition is 
declining, though not precipitously. For example, according to a 
program official who previously served as a commanding officer on an 
icebreaker, stated that the decline in condition of those assets has 
not been beyond what would be expected of assets 20 years or more of 
age. Our site visits showed that, on these older assets, crew members 
are spending increasing amounts of time and resources to troubleshoot 
and resolve maintenance issues. They indicated that because the systems 
and parts are outdated compared with the technology and equipment 
available today, it can be challenging and time consuming to diagnose a 
maintenance issue and find parts or determine what corrective action to 
take. For example, the propulsion control system on the 140-foot 
icebreaking tugs uses circuit cards that are no longer manufactured and 
have been superseded by computer control systems. While some assets are 
being operated more extensively than in the past to meet additional 
responsibilities, particularly homeland security, Coast Guard officials 
said that overages can have an impact on some assets, especially those 
with more complex systems and subsystems. The officials said that 
exceeding planned usage limits may leave less time to maintain these 
systems. They said that the deterioration of an asset and its systems 
from usage consistently above the limits would be reflected in periodic 
engineering assessments of the assets. Against this backdrop, 
performance indicators for the two missions show mixed results. A 
milder winter in 2005 may have contributed to the Coast Guard's ability 
to meet its primary domestic icebreaking performance target, which aims 
for limiting the number of days critical waterways are closed due to 
ice to 2 days during average winters. For the ATON mission, the main 
performance measure (the number of collisions, allisions, and 
groundings) has been declining for the past 5 years, indicating 
continual improvement, while a secondary measure (the percentage of 
time an aid-to-navigation system is performing) has been declining over 
the same period--a negative trend.[Footnote 3] In previous work, we 
found that many other factors, such as severity of weather, also 
affected outcome on performance measures. 

To continue to achieve the missions of its ATON and domestic 
icebreaking assets, the Coast Guard has taken a number of actions to 
develop program management tools or acquire new assets, made proposals 
to address aging assets, and conducted a study of what makes the best 
business case for outsourcing: 

* Actions taken or underway include developing a better measure for 
linking an asset's condition and its ability to carry out missions, a 
revised maintenance approach for newer assets, and a centralized system 
for tracking the condition and maintenance of smaller ATON boats. In 
addition, to better link asset conditions and funding decisions, the 
Coast Guard has developed a benefit-cost analysis tool to analyze the 
trade-offs involved in upgrading assets or continuing to maintain them, 
thereby helping the Coast Guard decide on the combinations of projects 
that will provide the most capability for the dollars invested. The 
Coast Guard has also acquired some newer assets: in 2004, it acquired 
the last of 30 new buoy tenders to replace older coastal and seagoing 
buoy tenders and in 2005, and it acquired a new icebreaker for the 
Great Lakes. These acquisitions have brought improved features to the 
fleet, such as computerized systems for positioning and propulsion 
control, enhanced multimission capabilities, and improved equipment for 
servicing navigation aids. 

* Proposals made include steps to address the remaining aging assets, 
but these steps have not been implemented, largely because of other 
funding priorities. To determine whether to rehabilitate or replace 
assets, Coast Guard officials stated that they use a process that 
considers things such as the condition of the assets and trends in 
maintenance costs. In 2002, the Coast Guard proposed a project to 
systematically rehabilitate or replace its other aging ATON and 
domestic icebreaking assets. Requests for funding this project have 
been denied or deferred by the Department of Homeland Security or the 
Office of Management and Budget since fiscal year 2004, apparently due 
to competition for limited resources with other Coast Guard 
initiatives, such as the Deepwater project for replacing cutters and 
aircraft used far out at sea. As a result, parts of the project have 
been separated into smaller components with lower funding requirements. 
For example, in 2006, the Coast Guard began acquiring new trailerable 
ATON boats to replace 80 boats currently in use. Of these smaller 
components, only this new boat acquisition has received funding. 

* The study conducted looked at what activities make the best business 
case for being outsourced to the private sector. While recognizing 
that, at the time of the study some ATON activities were being 
contracted to commercial sources on a limited basis, the study 
suggested that some asset classes related to the Coast Guard's ATON 
activities might be outsourced and merited further examination. 
However, according to the Coast Guard, potential disadvantages to 
outsourcing exist such as reduction of the Coast Guard's capacity to 
respond to hurricanes and other emergencies and disruption of the Coast 
Guard's personnel structure and ability to attract and retain 
personnel. 

We provided a draft copy of this report to the Department of Homeland 
Security and the Coast Guard for review. The Coast Guard provided 
technical comments, which have been incorporated where appropriate.

One of the Coast Guard's strategic goals is maritime mobility, that is, 
to facilitate maritime commerce, eliminate interruptions and 
impediments to the movement of goods and people, and maximize access to 
and enjoyment of the water. The two non-homeland security missions 
through which the Coast Guard achieves this goal are aids-to-navigation 
(ATON) and domestic icebreaking, which is part of ice operations. 

Aids-to-Navigation Mission: 

Through its ATON mission, the Coast Guard promotes safe waterways and 
an efficient Marine Transportation System. The Coast Guard has 
statutory responsibility to operate and maintain a system of maritime 
aids to facilitate navigation and to prevent disasters, collisions, and 
wrecks.[Footnote 5] To fulfill this mission, the Coast Guard operates 
over 53,000 aids. These aids-to-navigation are like road signs of the 
waterways and are placed along coasts and navigable waters as guides to 
mark safe water and to assist mariners in determining their position in 
relation to land and hidden dangers. These aids consist of both 
floating aids, such as buoys, and fixed aids, such as lights or signs 
mounted on pilings. See figure 1 for an example of a buoy and fixed aid-
to-navigation.

The Coast Guard uses several types of vessels to place and service its 
aids-to-navigation such as buoy tenders, construction tenders, and 
boats that make up its ATON fleet. These vessels are used to perform 
both periodic routine maintenance of aids and discrepancy response, 
when, for example, a light is extinguished or a buoy is moved from its 
intended location. The assets are shown in table 2.

Domestic Icebreaking Mission: 

Domestic icebreaking is a key component of the Coast Guard's ice 
operations mission, which facilitates the safe and efficient navigation 
on lakes, rivers, channels, and harbors during the winter season. The 
Coast Guard has statutory icebreaking responsibilities that are 
additionally addressed by an executive order that directs the Coast 
Guard to break ice in channels and harbors in order to keep them open 
to navigation.[Footnote 6] Like plowing snow-covered roads, the Coast 
Guard keeps areas of water open as much as is reasonably possible for 
commercial traffic in winter. It also performs icebreaking for search 
and rescue and prevention of flooding by ice. To conduct this mission, 
the Coast Guard uses assets that are specially designed with 
strengthened hulls. The key icebreaker types the Coast Guard uses are 
shown in table 3. 

Table 3: Domestic Icebreaking Assets: 

Asset type: 140-foot icebreaking tugs; 
Number of assets: 19; 
Asset description: The icebreaking tugs are specially configured for 
breaking ice on the Great Lakes, rivers, and coastal waters, and 
support aids to navigation. They have a crew size of 17 to 27, a 
maximum speed of 14.7 knots and an operating range of 4,000 nautical 
miles. Two of these assets are augmented by a 120-foot ATON barge and 
perform mostly ATON mission activities. These vessels were commissioned 
between 1979 and 1988; 
Asset photograph: [See PDF for Image]. 

Asset type: 65-foot small harbor tugs; 
Number of assets: 11; 
Asset description: The small harbor tugs perform shallow water 
icebreaking services and maintain short-range ATON in rivers and near-
shore areas. They also perform port security and search and rescue 
missions. They have a planned crew size of 6, a maximum speed of 10 
knots, and an operating range of 850 nautical miles. These vessels were 
built between 1962 and 1967;

Note: In June 2006, the Coast Guard commissioned a new 240-foot Great 
Lakes icebreaker that has multi-mission capabilities and will perform 
both domestic icebreaking and aid-to-navigation as its primary mission 
activities. It replaces a 290-foot icebreaker that was commissioned in 
1944. Because the new Great Lakes icebreaker has not yet completed ice 
trials, we did not include it in this table. 

[End of table] 

The Coast Guard classifies its vessel assets, such as those used in the 
ATON and domestic icebreaking missions, as cutters (assets 65 feet long 
or longer with adequate accommodations for crew to live on board) or 
boats (assets less than 65 feet in length that usually operate near 
shore and on inland waterways). For purposes of this report, the three 
main asset groups are ATON cutters, ATON boats, and domestic 
icebreakers. 

Icebreaking and ATON Assets Show Significant Increases in Time Spent on 
Homeland Security Missions since 2001: 

Since 2001, the Coast Guard's domestic icebreakers and ATON cutters 
have experienced significant increases in the time spent conducting 
missions related to homeland security. Most of this increase has come 
in the Ports, Waterways and Coastal Security (PWCS) mission, which 
involves such activities as conducting security patrols and escorting 
vessels. The increase was greatest for domestic icebreakers, which 
continue to be used more for homeland security missions than for 
icebreaking because of their availability during months when no 
icebreaking is needed. By contrast, ATON cutters and boats still spend 
most of their time on ATON-related activities, reflecting the year- 
round nature of the ATON mission. Some newer ATON cutters with greater 
multi-mission capabilities, however, continue to have a more diverse 
workload. Coast Guard officials said icebreakers and ATON vessels, 
while less than ideal for carrying out security missions, can perform 
these missions adequately. 

Domestic Icebreakers Show the Largest Increase in Time Spent on 
Homeland Security Missions: 

During fiscal years 2001 through 2005, the domestic icebreakers divided 
their time between several of the Coast Guard's 11 missions, but PWCS 
activities accounted for roughly half of all resource hours during 
fiscal years 2002 through 2005.[Footnote 7] PWCS activities grew 
quickly from 15 percent of total resource hours in fiscal year 2001 to 
53 percent in fiscal year 2002, and they have remained at 44 percent or 
more of total hours through fiscal year 2005. At the same time, 
icebreaking hours began at 41 percent in fiscal year 2001 and then 
dropped down to 13 percent in 2002, but ended at 26 percent in fiscal 
year 2005. The vast majority of this increase in PWCS has occurred in 
the New York City area with smaller increases in other East Coast 
ports.[Footnote 8] As figure 2 shows, the increase came about largely 
by adding to the total number of hours these assets were operated. The 
total number of resource hours for these assets grew from about 12,000 
hours in fiscal year 2002 to a high of about 20,000 the following year.

through 2005:

[End of figure] 

The increase in PWCS hours for domestic icebreakers mainly reflects 
their availability during those months when no icebreaking needs to be 
done. Icebreaking needs are typically greatest from December 15 to 
April 15. Coast Guard officials said that because icebreakers do not 
have a primary summertime mission, using them to conduct PWCS missions 
during slack periods has not limited the Coast Guard's ability to 
conduct routine icebreaking missions.[Footnote 9] Icebreaking hours, 
however, did see some marked shifts during this period--most notably a 
decrease in fiscal year 2002 followed by a substantial increase in 
fiscal year 2003. The decrease in 2002 appears related to two main 
factors: a mild winter, during which the Great Lakes region was 
virtually free of ice throughout December and most of January, and a 
change in the way the Coast Guard accounted for its use of icebreakers. 
The Coast Guard does not record resource hours under two mission 
categories simultaneously, and prior to the attacks on September 11, 
2001, resource hours used to break ice while escorting a vessel with 
hazardous cargo would only have been recorded as ice operations. After 
the attacks, these same hours could be logged either as PWCS or 
icebreaking at the discretion of the vessel's commanding officer. The 
increase in ice operations hours for fiscal year 2003 reflected an 
unusually severe winter in the Great Lakes. 

Increased workloads have placed some icebreakers above the maximum 
number of recommended operating hours for the assets. The maximum 
recommended operating level, called an "underway hours limit," reflects 
maximum use established from planning documents, missions, and 
maintenance requirements, and historic use. In particular, the 65-foot 
small harbor tug fleet exceeded their underway hours limit from fiscal 
years 2001 to 2003 by increasingly more hours, starting with being 10 
hours over the underway limit in 2001 and progressing to nearly 2,000 
hours over the underway limit in 2003. In contrast, the 140-foot 
icebreaking tugs were operated within their underway hours limit from 
2001 to 2005. 

Coast Guard officials said domestic icebreakers, while not their vessel 
of choice for maritime security missions, can perform all PWCS missions 
adequately except for shore side patrols.[Footnote 10] The Coast 
Guard's 87-foot coastal patrol boats are the preferred assets for PWCS 
missions. Commissioned since 1998, these boats can travel at up to 25 
knots and have a system that allows the crew to launch and recover 
small boats.[Footnote 11] Relative to these vessels, domestic 
icebreakers show both advantages and disadvantages (see table 4). 
Icebreakers are more capable of operating in cold weather, and their 
substantial size provides a significant presence on the waterways, but 
they are slower, less able to launch small boats, and pose increased 
training challenges for training crews in law enforcement.[Footnote 12]

Increase in Homeland Security Missions Is Less Extensive for ATON 
Assets: 

ATON assets also experienced an increase in use for homeland security 
missions after September 11, 2001, but to a much lesser degree than for 
domestic icebreakers. Overall, ATON assets were used for several of the 
Coast Guard's missions during fiscal years 2001 through 2005, but ATON 
remained the primary mission, accounting for more than 85 percent of 
the fleet's total resource hours for fiscal years 2001 to 2005. Time 
spent in PWCS activities increased from 4 percent of total resource 
hours in fiscal year 2001 to 10 percent in fiscal year 2002; 
since then, PWCS mission hours have steadily decreased (see fig. 3). 
Overall, PWCS activities accounted for 6 percent of resource hours 
during the period. 

Figure 3: Resource Hours for ATON Assets, Fiscal Years 2001 through 
2005: 

[See PDF for image] 

GAO analysis of Coast Guard data. 

[End of figure] 

When resource hours are analyzed more closely by type of ATON asset, 
there are significant differences in the amount of hours used for the 
PWCS mission. The increase in PWCS resource hours came primarily from 
cutters (vessels ranging in length from 65 to 225 feet). Overall, ATON 
activities account for about 79 percent of total resource hours for the 
cutters, compared with about 90 percent for ATON boats (vessels less 65 
feet in length). ATON boats were the only vessels that did not have as 
much of an increase in PWCS resource hours immediately after the 
attacks on September 11, 2001, though their use in PWCS activities did 
rise in fiscal year 2003. Among the ATON cutters, the newer cutters 
have greater multiple mission capabilities and consequently tend to be 
used more often in other missions. For example, ATON cutters acquired 
between 1944 and 1976 performed an average of 4 of the Coast Guard's 11 
missions during fiscal years 2001 through 2005, while the 225-foot 
seagoing buoy tender, which the Coast Guard completed the acquisition 
of in 2004, was used in all 11 of the Coast Guard's missions in fiscal 
years 2004 through 2005. 

Available Evidence Indicates Condition of Assets Varies Greatly and 
Mixed Impact on Mission Performance: 

The available evidence does not give a consistent picture of how usage 
trends may be affecting the condition of these assets and, ultimately, 
the Coast Guard's ability to meet performance goals for icebreaking and 
ATON missions. We analyzed three types of evidence related to 
condition--the Coast Guard's primary measure for reporting asset 
condition, overall trends in maintenance expenditures on each type of 
asset, and a body of anecdotal evidence gathered primarily through 
interviews with Coast Guard personnel and site visits to various 
installations. The Coast Guard's primary condition measure shows some 
assets meeting the operating standard and others falling below it. 
However, the current measure for asset condition is not clearly linked 
to mission performance, but the Coast Guard is working on developing a 
measure that links the two. Trends in maintenance costs and the 
anecdotal evidence we gathered tend to indicate that asset conditions 
are declining, though not substantially beyond what Coast Guard 
officials said they would expect for vessels of this age. Performance 
indicators for the icebreaking and ATON missions likewise show mixed 
results, with the Coast Guard meeting some performance goals and not 
meeting others. In part, these mixed results can be explained by the 
many other factors besides asset condition, such as the severity of 
weather in any given year. 

Current Condition Measure Is Limited and Does Not Show a Clear Pattern 
in Asset Condition: 

For icebreaking and ATON cutter assets, the Coast Guard's key summary 
measure of condition shows mixed results. This measure-- percent of 
time free (POTF)--of major casualties has been mixed.[Footnote 13] The 
Coast Guard's standard is 72 percent or better. Measured against this 
standard for fiscal years 2000 through 2004, the various types of 
icebreakers and ATON cutters vary considerably.[Footnote 14] As table 5 
shows, some assets, such as the 65-foot small harbor icebreaking 
tugboat and the 65-and 75-foot river buoy tenders met the standard 
nearly every year, while others such as the 140-foot icebreaking 
tugboat and the 75-foot, 100-foot, and 160- foot inland construction 
tenders met it either not at all or only once during the 5-year period. 
Fiscal year 2004 was the worst of the 5 years, with only two of the 
eight types of cutters meeting the standard.

The Coast Guard's condition measure for these assets, while 
instructive, needs to be viewed with some caution. As we have reported 
in our analysis of the condition of the Coast Guard's legacy deepwater 
assets, the measure captures only major equipment casualties, which 
degrade mission capabilities but does not capture minor equipment 
casualties that may also degrade mission capabilities.[Footnote 15] As 
such, this measure may underestimate the decline in asset condition. 
The Coast Guard has acknowledged the limitations of this measure and is 
working on a replacement for it, which will better determine specific 
mission impacts. 

The POTF condition measure applies to cutters; 
the Coast Guard only recently started tracking POTF data for assessing 
condition trends on ATON small boats. During the fiscal year 2000 
through 2004 period we reviewed, the Coast Guard did not have a 
centralized system for tracking the condition of these boats. Its 
internal assessment of the condition of the boats was based on two 
approaches, as follows: 

* For standard boats, which are purchased by Coast Guard headquarters 
and have similar capabilities and equipment for all boats of a 
particular type, the Coast Guard assessed condition by determining the 
boats' remaining service lives through a process referred to as ship 
structure and machinery evaluation boards (SSMEB). The SSMEB, which is 
conducted 10 years after a boat is commissioned and is repeated at 5-
year intervals, applied to two of the six types of ATON boats we 
reviewed. 

* For nonstandard boats, which are purchased by individual Coast Guard 
units for individual needs, the Coast Guard's assessment was based on 
anecdotal information from district boat managers, maintenance 
managers, annual boat inspection reports, and site visits. This 
approach was used on four of the six types of boats we reviewed. 

Using these approaches, the Coast Guard characterized most of these 
asset types as in fair to poor condition. By contrast, however, when 
the Coast Guard assembled POTF data for a portion of these boats in 
fiscal year 2005, the data did not support this assessment. The boats 
analyzed had average scores above the Coast Guard's goal of 72 percent. 
(App. III provides further details on condition measures for each of 
the ATON and domestic icebreaking assets.) 

Increasing Maintenance Costs Indicate Possible Condition Issues: 

For our second measure--trends in maintenance expenditures--the picture 
with regard to condition is more consistent than for our first measure: 
maintenance expenditures for domestic icebreaking and ATON cutters are 
increasing, even after taking inflation into account. We analyzed three 
types of maintenance costs[Footnote 16]: 

* Scheduled maintenance costs, which are planned for in advance and 
include such things as repainting the vessel; 

* Unscheduled maintenance costs, which are for unforeseen emergencies; 
and: 

* Engineering Logistic Center (ELC) costs, which include fleetwide 
projects that require engineering assistance (such as checking for 
watertight integrity) and therefore cannot be handled at the unit 
level. These projects, such as replacing a generator, help sustain 
capability but do not enhance it, according to Coast Guard officials. 

While there are some asset-by-asset variations, total maintenance costs 
for domestic icebreakers and ATON cutters increased during the period 
we examined (fiscal years 2001 through 2005).[Footnote 17] As figure 4 
shows, total annual maintenance costs for domestic icebreakers nearly 
doubled, from slightly more than $3 million to slightly more than $6 
million. The increase came primarily in two of the three categories in 
most years--scheduled maintenance costs and ELC costs. Although 
maintenance costs are also affected by the amount of funding available 
in any given year, according to Coast Guard officials, maintenance 
managers have discretion to move some funds to those assets most in 
need of maintenance money. Coast Guard officials have also said that 
these costs are indicative of condition issues. For example, an ELC 
official said that the increase in ELC costs was related to condition 
because the money was used for the overhaul of domestic icebreakers. In 
addition to the amount of funding available in any given year, these 
maintenance costs can also be impacted by a variety of other factors 
such as the pace of operations. For example, maintenance costs can be 
expected to increase as the pace of operations increases.

[End of figure] 

Total annual cost increases for ATON cutters showed a similar trend, 
more than doubling from over $13 million to over $32 million during the 
5-year period (see fig. 5). For ATON cutters, cost increases were 
greatest in ELC maintenance and unscheduled maintenance. As with 
icebreakers, Coast Guard officials considered these expenditures to be 
related to asset condition.

Evidence Gathered from Interviews, Site Visits, and Other Records also 
Indicate Condition Issues: 

Evidence we gathered during our discussions with maintenance personnel, 
our visits to various Coast Guard installations, and our review of 
other Coast Guard records also pointed to declining condition of a 
number of these assets. However, according a program manager who 
previously served as a commanding officer on an icebreaker, for some of 
the older assets, the decline in condition of those assets has not been 
beyond what would be expected of assets 20 years or more in age. During 
our interviews and site visits, Coast Guard personnel reported to us 
that crew members have had to spend increasingly more time and 
resources to troubleshoot and resolve maintenance issues on older 
domestic icebreaking and ATON assets. They indicated that because the 
systems and parts are outdated compared with the technology and 
equipment available today, it can be challenging and time consuming to 
diagnose a maintenance issue and find parts or determine what 
corrective action to take. For example, the propulsion control system 
on the 140-foot icebreaking tugs uses circuit cards that were state-of- 
the-art when the tugs were commissioned in the late 1970s to 1980s but 
are no longer manufactured today and have been superseded by computer 
control systems (see fig. 6). Coast Guard personnel said the lack of a 
readily available supply of these parts has forced maintenance 
personnel to order custom made parts or refurbish the faulty ones, 
increasing the time and money it takes to address maintenance problems. 
Finding knowledgeable individuals to identify problems with outdated 
equipment is difficult, they said, which further complicates 
maintenance. Crews of other assets we visited also confirmed the 
difficulty of diagnosing problems and obtaining replacement parts for 
other critical subsystems such as the main diesel engines.

Main Propulsion Control System, on the 140-foot Icebreaking Tug:

[End of figure] 

Since at least 2002, the Coast Guard has been on record as saying these 
assets are in decline. In a mission needs analysis issued that year, 
the Coast Guard concluded that its domestic icebreaking and ATON assets 
were affected in varying degrees with respect to safety, 
supportability, environmental compliance, and habitability, and that 
addressing these issues would require replacing or rehabilitating the 
assets.[Footnote 18] The analysis noted that the need to replace or 
rehabilitate inland buoy tenders and 45-foot buoy boats had been 
identified as early as 1993 but had not yet been addressed.[Footnote 
19] It also noted that the 21-foot trailerable aids-to-navigation boats 
and the 55-foot aids-to-navigation boats--most of which have yet to be 
replaced--had been extended beyond their projected service lives. 

When we asked Coast Guard officials if current usage patterns were 
precipitating the decline of these assets, they said that overages can 
have an impact on some assets, especially those with more complex 
systems and subsystems. The officials said that exceeding planned usage 
limits may leave less time to maintain these systems. They said that 
the deterioration of an asset and its systems from usage consistently 
above the limits would be reflected in periodic engineering 
assessments, known as SSMEBs, of the assets. In our site visits, we did 
learn of one example in which increased use of assets for security-
related purposes may be affecting condition. The example involves the 
140-foot icebreakers, which currently are being used extensively for 
security-related activities when they are not engaged in icebreaking 
activity. According to Coast Guard personnel, these icebreakers were 
designed to operate at maximum power for icebreaking; however, maritime 
security missions typically require several hours of idling, which is 
detrimental to the engine. Extended periods of idling, they said, 
causes oil discharge and sludge build up in the engine and mufflers. 
Thus, running assets in ways for which they were not designed could 
result in faster degradation of their condition. 

Performance Indicators for Icebreaking and ATON Missions Show Mixed 
Results: 

Against this backdrop of condition indicators, the Coast Guard's 
measures of performance for domestic icebreaking and ATON missions show 
mixed results, with several indicators showing that mission performance 
has been improving or largely unchanging, while at least one other 
indicator indicates a decline. 

* For domestic icebreaking, the Coast Guard's performance indicator is 
the number of days that ice leads to closures of waterways in the Great 
Lakes region--the region in which most domestic icebreaking activity 
occurs.[Footnote 20] The Coast Guard's performance goal is to have 2 or 
fewer closure days during average winters.[Footnote 21] During fiscal 
years 2001 through 2005 the Coast Guard met this goal every year but 1. 
The exception was fiscal year 2004, when waterways were closed for 4 
days. According to Coast Guard officials, however, vessel condition was 
not a factor in waterway closures; instead, they were related to an 
icebreaker's being diverted to free a stuck vessel and to a response to 
a commercial aircraft crash. 

* For ATON, the Coast Guard's primary performance indicator is the 
number of collisions, allisions, and groundings.[Footnote 22] Since 
these events can cause deaths and injuries, environmental and property 
damage, and lead to waterway closures that limit commercial and 
recreational activity, a decline in this measure is an improvement. 
During fiscal years 2001 through 2005, this measure declined--a 
positive development (see fig. 7).

Fiscal Years 2001 through 2005:

While the Coast Guard's primary ATON performance indicator was showing 
improvement, however, an important secondary measure was showing an 
adverse effect. This indicator, which measures the probability that an 
aid to navigation or a system of aids-to-navigation is performing its 
specified function at any randomly chosen time and is expressed as a 
percentage of total time, is the leading performance measure used in 
managing the ATON program, according to Coast Guard officials.[Footnote 
23] This measure has steadily declined since fiscal year 2002 (see 
table 6), and since a smaller percentage means fewer aids are 
available, a decline in this measure is an adverse development. Coast 
Guard officials said some of this decline was attributable to the 
condition of ATON cutters and boats for servicing the navigational 
aids, but they were not able to estimate how much of the decline could 
be attributed to this cause.[Footnote 24]

[End of table] 

In other work, we have noted that the Coast Guard's performance 
indicators can be affected by multiple factors and that there are 
challenges to using such measures in linking resources to 
results.[Footnote 25] The ability to meet icebreaking goals, for 
example, can be affected by the severity of the winter. In fact, when 
the Coast Guard met its goal for waterway closures in fiscal year 2005, 
Coast Guard officials attributed the result in part to less severe 
average ice conditions than in previous years. Similarly, the ability 
to keep navigational aids in working order can be adversely affected by 
such uncontrollable factors as the severity of a hurricane or winter 
storm season. 

The Coast Guard has launched a number of initiatives designed to 
address challenges in linking resources to results of these 
missions.[Footnote 26] These initiatives followed program assessments 
conducted by the Office of Management and Budget, which completed an 
assessment of the ATON program in 2002 and the domestic icebreaking 
program in 2004.[Footnote 27] For the ATON program, the assessment 
determined that the program did not demonstrate results and recommended 
that the program have specific long-term performance goals that focus 
on outcomes. The assessment of the domestic icebreaking program 
determined that the program was effective, but that more ambitious 
performance targets needed to be set. In response to these findings, 
the Coast Guard has worked to set long-term performance targets and 
develop new measurement frameworks to align with OMB's recommendations. 

To Continue to Achieve the Missions of Its ATON and Domestic 
Icebreaking Assets, the Coast Guard Has Taken Actions, Made Proposals, 
and Studied Outsourcing Possibilities: 

The Coast Guard has considered or proposed a wide variety of actions to 
continue to achieve the missions that its domestic icebreaking and ATON 
assets perform and is moving ahead with several of them. Actions under 
way include developing new ways to measure asset condition, manage boat 
and cutter maintenance, and make choices about which maintenance 
projects to conduct. The Coast Guard has also acquired some new buoy 
tenders and a new icebreaker, though the bulk of its icebreaking and 
ATON fleet remains at or beyond projected service lives. Coast Guard 
officials stated that to determine whether and when to replace or 
rehabilitate aging assets, factors such as the assets' condition and 
trends in maintenance costs, among other things, are taken into 
account. Proposals to systematically rehabilitate or replace these 
assets have been denied or deferred by DHS or the Office of Management 
and Budget (OMB), apparently due to competition from initiatives such 
as the $24-billion Deepwater project for replacing or renovating other 
Coast Guard vessels and aircraft. In response, the Coast Guard has 
separated the proposals into smaller parts and is trying to fund some 
projects from within the Coast Guard's budget. Finally, the Coast Guard 
studied what mission activities make the best business case for 
outsourcing of functions to the private sector, but states that 
potential disadvantages to outsourcing exist such as loss of 
capabilities and inability to retain personnel. 

Actions Have Been Taken to Manage Assets and Acquire Some New Ones: 

Three main steps to manage assets are under way, and several 
acquisitions have been completed in both the icebreaking and ATON 
fleets. 

Coast Guard Is Developing a More Robust Condition Measure: 

The Coast Guard is working on the development of a new measure to track 
an asset's condition. As mentioned above, the Coast Guard's previous 
measure, percent of time free of major casualties, did not capture the 
extent to which equipment casualties degraded mission capabilities. 
Called "percent of time fully mission capable," this new measure is 
intended to more directly link a cutter's condition to its mission 
capability. Developed after our examination of the condition of 
deepwater assets, this measure will be used for ATON and domestic 
icebreaking assets as well.[Footnote 28] For the new measure, the Coast 
Guard is developing codes that rank the degree of importance of each 
piece of a cutter's equipment to each mission that the cutter could 
perform. The Coast Guard plans to use these codes in casualty reports, 
providing engineers and operators with information about the impact of 
equipment casualties on each possible mission. This information will 
then be used in calculating the condition measure for each cutter class 
and mission. This information would allow Coast Guard officials to 
determine, for example, the degree of icebreaking capability of its 
domestic icebreaking fleet at any given time. Coast Guard officials 
said they expect final approval of this measure this year. 

Coast Guard Is Implementing New Approaches to Manage ATON Boat and 
Cutter Maintenance: 

The Coast Guard is implementing a centralized boat maintenance 
initiative to improve the management of its boat fleet, which includes 
many ATON boats. In contrast to the previous approach in which local 
boat operators managed boat maintenance and oversaw the spending of 
maintenance funds, the new initiative places management of boat 
maintenance and expenditures with naval engineers. According to the 
Coast Guard, the key advantages of this initiative include standardized 
maintenance practices for the boats, better oversight of maintenance 
funding, and enhanced tracking and analysis of casualties. In addition, 
it should improve the tracking of the condition of the Coast Guard's 
small boat fleet, which has lacked a centralized tracking system. Known 
as Centralized Boat Maintenance Management, this initiative is expected 
to be rolled out Coast Guard-wide by fiscal year 2008 if adequate 
resources and personnel are available. 

Since 2002, the Coast Guard has also been gradually implementing a 
maintenance approach called "condition based maintenance" for select 
subsystems and parts of its newer coastal and seagoing buoy tending 
cutters.[Footnote 29] Under this approach, the condition of a part or 
subsystem, such as the main diesel engine, is evaluated or assessed at 
regular intervals to determine whether it needs to be replaced or have 
maintenance performed. Parts or systems would be replaced or receive 
maintenance only if their condition showed excessive wear or did not 
perform at an acceptable level. Under the previous approach, 
maintenance occurred at time-based intervals even if the part showed no 
excessive wear or performed acceptably. The key advantage of the 
change, according to Coast Guard officials, is reduced costs. For 
example, the Coast Guard estimated that it reduced drydock costs 
related to maintaining newer coastal and seagoing buoy tenders $2 
million in fiscal year 2005. The Coast Guard is considering expanding 
the use of this maintenance approach to other subsystems of the newer 
buoy tending assets and the new Great Lakes icebreaker commissioned in 
2006. 

Coast Guard Is Developing a Tool to Better Prioritize Upgrades and 
Maximize Asset Capabilities: 

In 2002, we recommended that the Coast Guard develop a long-term 
strategy to set and assess levels of mission performance.[Footnote 30] 
We found this was an important step to take because it links 
investments to asset capabilities and mission priorities so that the 
Coast Guard can better decide how limited budget dollars should be 
spent. The Coast Guard has been working to apply the principles behind 
such a strategy to (1) better prioritize the projects needed to upgrade 
assets such as aging ATON and domestic icebreakers and (2) obtain the 
greatest overall mix of capabilities for its assets within its budget 
in order to maximize mission performance. The tool it is developing is 
called the Capital Asset Management Strategy (CAMS). 

CAMS is designed to analyze the capability trade-offs for upgrades and 
maintenance projects across asset classes, allowing the Coast Guard to 
determine which combination of projects will provide the most 
capability for the dollars invested. These analyses take into account 
such factors as asset condition, the asset's importance to specific 
missions, and the relative importance of missions. The Coast Guard 
continues to refine CAMS and expects to have it in full use beginning 
with the budget for fiscal year 2009. The recommendations stemming from 
CAMS are intended to augment the information currently provided to 
decision makers in the budget development process. 

Coast Guard Acquired Some New Assets: 

Since the 1990s, the Coast Guard has been able to replace buoy tenders 
with new assets that represent about 15 percent of its current ATON 
fleet. From 1996 to 2004, the Coast Guard commissioned 14 new 175-foot 
coastal buoy tenders and 16 new 225-foot seagoing buoy tenders to 
replace an aging fleet of 11 coastal and 27 seagoing buoy tenders that 
were built between 1942 and 1971. The new buoy tenders have improved 
capabilities such as the following: 

* A computerized positioning system that automates the task of holding 
the vessel in place while working on a navigational aid. Previously, 
this task had to be done manually, requiring the crew to constantly 
monitor and maintain the vessel's position, sometimes for up to 10 
hours at a time. The system relieves the crew of this task and reduces 
safety concerns associated with crew fatigue. 

* Bow and stern thrusters to enhance the vessels' maneuverability and 
improve the crew's ability to maintain position. 

* Hydraulic chain stoppers and winches to reduce the number of crew 
members required to do the work and enhance safety (see fig. 8). 

* Accommodations that allow for dual gender crews, increasing the Coast 
Guard's ability to allow women to serve on the vessels.

[End of figure] 

These and other features also allow the newer buoy tenders to carry out 
other missions, according to a Coast Guard official involved in their 
design and acquisition. Their size, stability, and maneuverability are 
useful for such missions as search and rescue, homeland security, and 
law enforcement, and they have specific capabilities for dealing with 
other duties as skimming oil or mounting machine guns for security 
patrols. With their sizeable fuel tanks and storage capacity, they can 
also serve as logistics support platforms to restock vessels involved 
in drug interdiction and other activities. For 7 weeks in 2005, for 
example, one tender served as a supply platform for a Coast Guard 
vessel conducting drug interdiction patrols. According to Coast Guard 
officials, this enabled the patrol vessel to remain on patrol in the 
area for a longer period of time than it would have otherwise with its 
limited fuel and storage capacities. 

Besides the buoy tenders, the Coast Guard commissioned a new 240-foot 
multimission icebreaker in 2006 to replace a 62-year-old icebreaker and 
an aging buoy tender on the Great Lakes. The new icebreaker has 
enhanced icebreaking capabilities and the same ATON capabilities as the 
newer seagoing buoy tenders, enabling it to work on navigational aids 
in ice conditions as well as during other times of the year when no 
icebreaking is needed. 

Additional Proposals to Rehabilitate or Replace Aging Assets Remain 
Largely Unfunded: 

Despite the new acquisitions, more than half of the assets in the 
domestic icebreaking and ATON fleet have reached or are nearing the end 
of their service lives. Coast Guard officials stated that they use a 
process that considers information such as how close the assets are to 
the end of their design life, the condition of the assets as determined 
by periodic assessments, and trends in maintenance costs, among other 
things to determine whether to rehabilitate or replace these aging 
assets. This information is used to identify the asset types that are 
most in need of replacement or major maintenance, and therefore should 
be given greater consideration in maintenance planning and budgeting. 

In 2002, the Coast Guard proposed options for systematically 
rehabilitating or replacing 164 cutters and boats in these 
fleets.[Footnote 31] According to Coast Guard officials, these options 
were proposed after determining that the age, condition, and cost of 
operating these assets would diminish the capability of the Coast Guard 
to carry out ATON and domestic icebreaking missions over time without 
rehabilitation or replacement of some or all of the assets. In 2004, it 
completed a preliminary analysis of four approaches, including the 
status quo--that is, maintaining the existing fleet. This analysis 
provided an estimate of the total life-cycle costs for each approach 
over a 33-year period from fiscal year 2005 to fiscal year 
2037.[Footnote 32] (See table 7 for a description of each approach.) 
Estimated costs ranged as high as $8.5 billion; 
however, Coast Guard officials emphasized that these estimates were 
preliminary and are not reliable. As a result, we are not reporting 
these numbers in detail. 

Table 7: Approaches to Replace or Rehabilitate ATON and Domestic 
Icebreaking Assets under the Integrated ATON Platform Modernization 
Project: 

Status quo: The existing fleet of ATON and domestic icebreaking assets 
would receive maintenance as needed to maintain current operations. 

Rehabilitation: Nearly all existing assets[A] would undergo major 
rehabilitation projects whose effect is expected to last 15 years for 
most vessels after which another major rehabilitation would be 
required. 

Replace: All existing assets would be replaced with a system of new 
standardized assets. 

Rehabilitate/replace: Depending on the condition of certain asset 
types, the assets would be either replaced with new assets or 
rehabilitated.

[A] Under this alternative, trailerable aids-to-navigation boats and 
the 45-foot buoy boats would be replaced. 

[End of table] 

No funds have been allocated to pursue this project further, apparently 
due to competing funding requests for replacing or rehabilitating other 
Coast Guard assets. According to a Coast Guard program official, 
although resource proposals to carry out this project were made during 
the budget planning processes for fiscal years 2004 through 2007, the 
requests were either deferred or denied by DHS or the Office of 
Management and Budget. Coast Guard officials involved in the program 
said they were not aware of the exact reasons why the requests were 
terminated or deferred. The officials said that the funding demands 
from other major Coast Guard programs already underway (such as the 
Deepwater program for replacing or rehabilitating aircraft and cutters 
with greater at-sea capability) that likely had higher priority in the 
competition for limited resources combined with the large scope and 
size of the proposed project, may have prevented the project from being 
funded. 

Without specific funding to move the project forward, the Coast Guard 
has attempted to break the project into smaller components and pursue 
potential funding from within the Coast Guard's budget, focusing on the 
assets most in need of maintenance or replacement. In February 2006, 
the Coast Guard began a project to replace its fleet of 80 trailerable 
aids-to-navigation boats with new boats that have enhanced capabilities 
to do ATON work as well as other missions.[Footnote 33] The enhanced 
capabilities include equipment to lift navigational aids out of the 
water for service, more deck space for working on these aids, an 
elevated work platform for working on aids that are high in the water, 
and faster speeds to reduce transit times. The Coast Guard intends for 
the new boats to be more multimission capable. For example, their added 
speed and deck space will help with search and rescue missions, and 
they will have gun mounts for use in law enforcement or maritime 
security missions. 

According to a Coast Guard official, this acquisition would cost 
approximately $14.4 million if all 80 boats are purchased and would 
bring on new boats over a 5-year period as funds allow.[Footnote 34] 
The Coast Guard official responsible for the project said the Coast 
Guard intends to make the purchases using a funding stream appropriated 
for the maintenance of nonstandard boats that can be allocated to the 
boats with the most pressing maintenance or recapitalization needs. 
Availability of these funds, however, depends on the condition and 
maintenance needs of other nonstandard boats; if this funding has to be 
applied to meet other needs, such as unanticipated problems, it may not 
be available for purchasing these boats. 

Separate from this effort to acquire new trailerable boats, the Coast 
Guard has made a request as part of the budget process to begin 
rehabilitating aging river buoy and construction tenders. This project, 
which will focus on rehabilitating the systems within the engine rooms 
of the assets, is estimated to cost approximately $75 million. The 
Coast Guard plans to include this project in future budget requests. 
Coast Guard officials indicated that they were submitting this request 
because these assets were determined to be in the worst condition. 

Study Identified Outsourcing Possibilities but May Face Disadvantages 
to Implement: 

In 2004, the Coast Guard examined possibilities for outsourcing 
missions in response to an OMB assessment of the ATON program.[Footnote 
35] As a result of that assessment, Coast Guard and OMB officials 
agreed to study which ATON activities make the best business case for 
being performed by contractors outside of the Coast Guard with minimal 
impact on the Coast Guard's ability to carry out its other 
missions.[Footnote 36] The subsequent study, completed in April 2004, 
found that inland construction tenders spent most of their resource 
hours on the ATON mission with minimal impact or use in other missions 
and provided one of the best opportunities for further study of 
outsourcing.[Footnote 37] However, the study did not quantify the 
potential benefits that could be derived from outsourcing these 
activities. 

In August 2006 the Coast Guard completed an analysis as to whether ATON 
functions could feasibly be outsourced, and which parts, if any, were 
inherently governmental in nature.[Footnote 38] The objective of this 
analysis was to compare the Coast Guard's inland construction and river 
buoy tender operating costs with representative private sector marine 
industry costs and make recommendations regarding the feasibility to 
commercially support and operate the inspection, servicing, and 
contingency response capability of the ATON mission and assets. 
According to Coast Guard officials, the results will be incorporated 
into future acquisition plans for replacing the current capabilities 
represented by inland construction tenders and river buoy tenders. This 
Coast Guard analysis was finalized after we had completed our audit 
work. Therefore, we were unable to obtain and review the study in time 
for the final preparation of this report. 

Although possibilities for outsourcing were identified, outsourcing 
also carries potential disadvantages, according to Coast Guard program 
officials. Potential disadvantages they mentioned include the 
following: 

* Outsourcing could lead loss of "surge" capability--that is, the 
capacity to respond to emergencies or unusual situations. In part, this 
capability may be needed within the ATON or icebreaking mission itself, 
such as when a hurricane or ice destroys or damages a large number of 
navigation aids. In the case of Hurricane Katrina, Coast Guard 
officials stated that because the Coast Guard had ATON assets such as 
construction tenders, crews were able to begin working immediately to 
repair damaged aids and get the waterways open to maritime traffic 
again. This "surge" capability may also be needed for other missions, 
such as occurs when ATON assets can be used to support search and 
rescue efforts. In the aftermath of Hurricane Katrina, for example, 
some ATON assets provided logistical support for first responders or 
transported stranded individuals. 

* Outsourcing may disrupt the Coast Guard's personnel structure and 
weaken the agency's ability to attract and retain personnel. 
Specifically, they are concerned that outsourcing would likely reduce 
opportunities that provide important experience for personnel to 
advance in their careers and eliminate positions that typically have 
more predictable work schedules than positions in some of the other 
Coast Guard's missions. 

Concluding Observations: 

The Coast Guard has been using its domestic icebreaking vessels and its 
ATON assets to a lesser extent, to accommodate the need for additional 
homeland security activities in the post-September 11 environment, and 
it is doing so thus far largely without curtailing ATON or domestic 
icebreaking activities or unduly straining these assets past their 
designed workloads. The available evidence also indicates that despite 
some decline in the condition of some asset types, the Coast Guard's 
ability to meet its aids-to-navigation and domestic icebreaking 
missions, as indicated by mixed outcomes of its key mission performance 
measures, has not shown clear trends of decline. Efforts by Coast Guard 
personnel to troubleshoot operational problems and to take other steps 
to keep assets operating appear to be one reason mission performance 
has not been further affected, and many other factors, such as the 
harshness of a winter or the severity of storm damage on navigation 
buoys and beacons, can also affect performance results. For the 
present, however, the impact of these additional mission 
responsibilities does not appear to be a cause for alarm. 

That said, the future of these assets bears close watching. The fact 
that many of the assets have or will be approaching the end of their 
design service lives could mean the need for rehabilitated or new 
assets may become more pressing in the future. Another issue is whether 
current operations, both in level and types of usage, are adding to 
these costs and incidents beyond what the Coast Guard would normally 
expect. For example, operating domestic icebreakers beyond their 
underway hours limit--could potentially accelerate the level of 
decline. If this is the case, using these assets to meet security 
missions could be meeting the Coast Guard's immediate needs but 
accelerating the need for replacement or rehabilitation. According to 
Coast Guard officials, the Coast Guard's attempt to systematically 
rehabilitate or replace its ATON and domestic icebreaking fleet was 
proposed at a time when competing demands likely caused postponements 
of requests for the needed funds. These competing demands, reflected 
largely in the Coast Guard's expensive and lengthy Deepwater asset 
replacement program, will continue for some time, as will other 
pressures on the federal budget. The Coast Guard is moving to improve 
the process it uses to set budget priorities through actions such as 
its new tool to link asset condition and funding decisions to better 
identify the projects that will provide the most capability with the 
limited funds that are available. Given that many of these actions are 
recent and need a chance to work, it is too early to evaluate their 
effectiveness. However, even as the Coast Guard takes steps to 
determine how best to replace or rehabilitate its assets, limited 
budgetary resources combined with other competing asset replacement 
programs already in process will likely continue to challenge the Coast 
Guard to find sufficient resources to carry out the options identified.

Appendix I: Objectives, Scope, and Methodology: 

This report examines the time spent by the U.S. Coast Guard's domestic 
icebreaking and ATON assets on various missions, the condition of these 
assets, and the actions the Coast Guard has taken to continue to 
achieve the missions of these assets. Our work focused on three key 
questions: (1) What are the recent trends in the amount of time these 
assets have performed various missions? (2) What is the condition of 
the Coast Guard's ATON and domestic icebreaking assets and how has 
their condition impacted the performance of their primary missions? (3) 
What actions has the Coast Guard taken to continue to achieve the 
missions of its ATON and domestic icebreaking assets? 

In identifying trends in the amount of time spent on missions and the 
impact of these trends, we analyzed data from the Coast Guard's 
Abstract of Operations (AOPS) database, which tracks resource hours for 
each asset. For each asset type within our scope, we examined trends in 
the number of resource hours spent between fiscal years 2001 and 2005 
conducting each of the Coast Guard's missions.[Footnote 39] To 
determine the reliability of this data, we (1) reviewed the results of 
previous reliability assessments we have conducted of this data for 
other work and (2) confirmed with the AOPS program manager that the 
data and the manner in which it is managed has not changed since the 
previous assessment that would affect its reliability. We determined 
that the data was sufficiently reliable for the purposes of this 
report. We supplemented our analysis of these resource hours with 
documentation from interviews with asset program managers and crews of 
ATON and domestic icebreaking assets. 

In assessing the condition of the assets during fiscal years 2001 to 
2005, we analyzed what Coast Guard officials identified as the best 
available condition measures. We obtained concurrence from the Office 
of Naval Engineering and the Office of Cutter Forces that the 
appropriate measures to use for the condition of assets were percent of 
time free of major casualties, scheduled/unscheduled/Engineering 
Logistics Center maintenance costs, and estimated deferred maintenance 
costs. To determine the reliability of this data, we (1) reviewed the 
results of previous reliability assessments we have conducted of this 
data for other work and (2) examined responses the Coast Guard provided 
to a questionnaire we sent requesting updated information on the 
administration and oversight of the databases. We determined that the 
data was sufficiently reliable for the purposes of this report. We 
supplemented our analysis of these measures with documentation from 
internal Coast Guard reports, as well as from interviews of asset 
program managers at Coast Guard headquarters and crewmembers of the 
assets located in the field. In addition to talking with crewmembers, 
we directly observed the condition of various assets during our site 
visits to Alameda, Calif; Bayonne, N.J; Buchanan, Tenn; Baltimore, Md; 
Mobile, Ala; Seattle, Wash; Sault St. Marie, Mich; and Atlantic Beach, 
N.C. These assets were selected to provide diversity in terms of type 
and age of asset and geographic location. In addition, we interviewed 
Coast Guard officials with the Area Commands in Alameda, Calif., and 
Portsmouth, Va., as well as in Districts 5 and 13. 

To determine the actions that the Coast Guard has undertaken to 
continue to achieve the missions of its ATON and domestic icebreaking 
assets, we interviewed officials with the Coast Guard's Engineering and 
Logistics Center, Engineering and Logistics Directorate, Office of 
Naval Engineering, Office of Boat Forces, and Office of Cutter Forces. 
To obtain information on newer assets the Coast Guard has acquired, we 
also made site visits to interview personnel and observe the assets in 
San Francisco, Calif; Atlantic Beach, N.C; Baltimore, Md; Cheboygan, 
Mich; and Mobile, Ala. To determine what proposals the Coast Guard has 
made to rehabilitate or replace its ATON and domestic icebreaking 
assets, we reviewed Coast Guard project documents and interviewed 
officials at Coast Guard headquarters. We did not, however, verify the 
accuracy of the cost estimates provided for those proposals. Finally, 
to determine the work the Coast Guard has done to study the outsourcing 
of ATON and domestic icebreaking mission activities and the potential 
impact of outsourcing those activities, we interviewed Coast Guard 
officials at headquarters as well as officials and crew members in the 
field. We also reviewed the completed business case analysis of 
outsourcing opportunities for ATON mission activities. 

We performed our review from July 2005 to August 2006 in accordance 
with generally accepted government auditing standards.

Appendix II: Mission Resource Hours of ATON and Domestic Icebreaking 
Assets, Fiscal Years 2001 to 2005: 

Appendix II provides information on the number of resource hours Coast 
Guard ATON and domestic icebreaking assets have spent on various Coast 
Guard missions during fiscal years 2001 through 2005. The Coast Guard 
maintains information, on a program-by-program basis, about how 
resources, such as vessels, boats, and aircraft, are used. Each hour 
that these resources are used is called a resource hour. Resource hours 
are accumulated and reported by quarter and represent the time spent by 
the Coast Guard's major assets to conduct its programs. The table 8 
shows by asset type, the hours ATON and domestic icebreaking assets 
have spent on each of Coast Guard's missions for each fiscal year, from 
2001 through 2005. The percentage of each asset types' total fiscal 
year resource hours that these hours represent is shown in parenthesis.

Appendix III: Condition Measure of ATON and Domestic Icebreaking 
Assets, Fiscal Years 2000 to 2005: 

Condition Measure for ATON and Domestic Icebreaking Cutters: 

Appendix III provides information on the condition of the Coast Guard's 
ATON and domestic icebreaking assets. The Coast Guard's key summary 
measure of condition--percent of time free (POTF)--of major casualties 
shows a mixed picture of condition for ATON and domestic icebreaking 
cutters. However, the measure captures only major equipment casualties, 
which degrade mission capabilities but does not capture minor equipment 
casualties that may also degrade mission capabilities. As such, this 
measure may underestimate the decline in asset condition. The Coast 
Guard has acknowledged the limitations of this measure and is working 
on a replacement for it. Because the Coast Guard is in the process of 
developing a new condition metric and did not have fiscal year 2005 
data available, our analysis covers fiscal years 2000 through 2004. See 
table 9 for individual POTF figures for the ATON and domestic 
icebreaking cutter assets for fiscal years 2000 through 2004.

Condition Measure for ATON Boats: 

The Coast Guard has less data for ATON boats, with POTF figures 
available for only fiscal year 2005. Based on these figures most boats 
appear to be in fair to poor condition. In addition to these figures, 
the Coast Guard has performed an internal assessment of condition using 
two approaches, one for standard and another for nonstandard boats. For 
standard boats the Coast Guard assessed condition through a process 
referred to as ship structure and machinery evaluation boards (SSMEB). 
While, for nonstandard boats the Coast Guard assessed condition by 
obtaining anecdotal evidence from district managers, maintenance 
managers, annual boat inspection reports, and site visits. This 
internal assessment, however, seems to further support our original 
finding that the Coast Guard's POTF figure may be underestimating 
condition. As you will see in table 10 below, while the 45-foot buoy 
boat and 21-foot trailerable aids-to-navigation boat had POTF 
percentages above 90 percent, their internal assessment of condition 
was rated at poor. 

Table 10: Condition of ATON Boats as Evidenced by POTF and Internal 
Coast Guard Assessment: 

Asset: Standard boats: 55-foot aids-to-navigation boat; 
POTF for FY 2005: Standard boats: 90.1%; 
Coast Guard assessment of condition: Standard boats: Fair. 

Asset: Standard boats: 49-foot buoy stern loading boat; 
POTF for FY 2005: Standard boats: 88.1%;

Appendix IV: Maintenance Trends of ATON Cutter and Domestic Icebreaking 
Assets, Fiscal Years 2001 to 2005: 

Maintenance Trends: 

Appendix IV provides information on the maintenance costs spent on the 
Coast Guard's ATON cutter and domestic icebreaking assets during fiscal 
years 2001 to 2005. Maintenance cost data for domestic icebreakers and 
ATON cutters shows a consistent increasing trend. The cost figures are 
broken out by scheduled (planned maintenance), unscheduled (unforeseen 
maintenance), and Engineering Logistic Center (ELC) (fleetwide projects 
that require engineering assistance) amounts, which allow for a more 
specific analysis as to the type of increase being incurred. Table 11 
shows the individual maintenance cost data, adjusted for inflation 
using 2005 dollars, for ATON cutters and domestic icebreakers for 
fiscal years 2001 through 2005.

FOOTNOTES 

[1] The Coast Guard is also responsible for operating and maintaining 
the nation's fleet of polar icebreakers. We did not examine those polar 
icebreaking assets as part of this review. 

[2] The Coast Guard defines a cutter as any Coast Guard vessel 65 feet 
in length or greater, having adequate accommodations for crew to live 
on board. Boats are defined as those vessels under 65 feet in length 
that usually operate near shore and on inland waterways. 

[3] An allision is a collision between a vessel against a fixed or 
stationary object. 

[4] The Coast Guard's homeland security and non-homeland security 
missions are delineated in section 888 of the Homeland Security Act of 
2002 (P. L. 107-296, 116 Stat. 2135, 2249 (2002)). Starting with the 
fiscal year 2007 budget, however, OMB has designated the Coast Guard's 
drug interdiction and other law enforcement programs as non-homeland 
security missions for budgetary purposes. 

[5] The Coast Guard's statutory aids-to-navigation authorities include, 
for example, 14 U.S.C. § 2, and 14 U.S.C. § 81. 

[6] 14 U.S.C. § 2; Exec. Order No. 7521, 1 Fed. Reg. 2184 (1936). 

[7] The Coast Guard maintains information, on a program-by-program 
basis, about how resources (assets such as ships and boats) are used to 
conduct its program missions. Each hour that these resources are used 
is called a resource hour. Resource hours do not include things such as 
the time that the resource stands idle or the time that is spent in 
maintaining it. "Support" was also a mission identified by the Coast 
Guard; however, because this mission accounted for time spent on non- 
mission activities such as public affairs and training, we did not 
consider these hours recorded as "Support" to be "resource hours." 

[8] In addition the Coast Guard also has several icebreakers stationed 
at locations along the East Coast. Of the locations these icebreakers 
are stationed, the demand for additional presence and patrols has been 
greatest in New York City. Sector New York has a requirement of 116 
hours per day of PWCS patrols. Other sectors have little or no hours 
required. 

[9] According to a Coast Guard official, maintenance on the icebreakers 
is often done during the summer period and PWCS missions that occur 
during this time can result in planned maintenance being rescheduled. 
Although the assets have been ready to break ice when needed so far, 
the Coast Guard official stated that depending on how much the 
maintenance is delayed as well as whether there are any additional 
maintenance problems discovered, the potential exists for the assets 
not being ready if icebreaking is needed earlier than expected. 

[10] Shore-side patrols typically involve visiting a maritime facility 
and providing a law enforcement presence on land. The patrols are 
typically conducted by a Coast Guard shore unit. 

[11] A knot is equivalent to 1 nautical mile per hour, approximately 
1.85 kilometers or 1.15 miles-per-hour. 

[12] To qualify for these crews, team members and officers must attend 
training in maritime law enforcement, where they are trained in the use 
of weapons including firearms. 

[13] A major casualty is a deficiency in mission-essential equipment 
that causes the major degradation of a primary mission or loss of at 
least one primary mission. 

[14] The Coast Guard is in the process of developing a new condition 
metric and did not have fiscal year 2005 data available. Consequently, 
our analysis covers fiscal years 2000 through 2004. 

[15] GAO, Coast Guard: Progress Being Made on Addressing Deepwater 
Legacy Asset Condition Issues and Program Management, but Acquisition 
Challenges Remain, GAO-05-757 (Washington, D.C.: July 22, 2005). The 
Deepwater fleet consists of 186 aircraft and 88 cutters of various 
sizes and capabilities, which play a critical role in all Coast Guard 
homeland and non-homeland security missions. 

[16] We also examined a fourth category--deferred maintenance, which is 
the amount of scheduled maintenance that must be postponed in order to 
pay for unscheduled repairs. A previous GAO study found that a drop in 
this account is not necessarily an indicator that the condition of the 
assets are improving but rather a result of the Coast Guard having more 
money to address the maintenance needs. Due to this limitation we did 
not include our analysis of a sub-account within deferred maintenance 
which indicated a declining trend. Data to conduct an analysis on ATON 
small boats are not available. 

[17] Given the limitations of the Coast Guard data, we could not 
analyze maintenance costs for ATON small boats, and were unable to draw 
any conclusions about the condition of the ATON boats based on their 
maintenance costs. Starting in fiscal year 2003, the districts began 
shifting responsibility of boat maintenance from the district level to 
a centralized area level. Due to the segregated approach in which boat 
maintenance was carried out previously, maintenance data for the period 
we examined is inconsistent. Further complicating the analysis of this 
data is the fact that it is not broken out by scheduled and unscheduled 
costs, which would allow for identification of trends in unplanned 
maintenance and better reflect issues with condition. Finally, the 
maintenance cost figures reflect only half of the costs for standard 
boats, which is less than 40 percent of the total boat fleet. 

[18] Absent from the analysis were the newer 49-foot stern loading buoy 
boats, and the 175-foot and 225-foot seagoing buoy cutters. 

[19] This need was to be met by acquiring a new 49-foot buoy stern 
loading boat, but the existing 45-foot buoy boat assets were continued 
in service when the Coast Guard determined that the 49-foot boats could 
not support the needs for all locations across the country. 

[20] In our recent review of the performance measures for non-homeland 
security missions, we found that although the Coast Guard breaks ice in 
many East Coast ports and waterways, according to Coast Guard 
officials, the measure focuses on the Great Lakes region because it is 
a large commerce hub where the icebreaking season tends to be longer 
and where ice has a greater impact on maritime transportation. Coast 
Guard program officials at agency headquarters said that they are in 
the early stages of developing a new primary performance measure that 
will incorporate domestic icebreaking activities in areas beyond the 
Great Lakes. For more information, see GAO, Coast Guard: Non-Homeland 
Security Performance Measures Are Generally Sound, but Opportunities 
for Improvement Exist, GAO-06-816 (Washington, D.C.: Aug. 16, 2006). 

[21] The Coast Guard has a goal of 8 or fewer days during severe 
winters. 

[22] The Coast Guard defines an "allision" as a vessel collision with a 
fixed object. 

[23] The Coast Guard's primary indicator--collisions, allisions, and 
groundings--is the measure included in external performance reports, 
but it reflects many factors outside the aids to navigation mission, 
such as weather, dredging, and vessel equipment standards. 

[24] Coast Guard officials also said that, in some cases, the lack of 
availability was related not to vessel's condition but to its use in 
other missions. For example, seagoing and coastal buoy tenders may be 
called upon to respond to unexpected events like hurricanes, precluding 
their use in fixing navigational aids. 

[25] See, for example, GAO, Coast Guard: Relationship between Resources 
Used and Results Achieved Needs to Be Clearer, GAO-04-432 (Washington, 
D.C.: Mar. 22, 2004). 

[26] For more information on these initiatives, see GAO, Coast Guard: 
Non-Homeland Security Performance Measures Are Generally Sound, but 
Opportunities for Improvement Exist, GAO-06-816 (Washington, D.C.: Aug. 
16, 2006). 

[27] These assessments were done using OMB's Program Assessment Rating 
Tool (PART), which is a diagnostic rating tool meant to provide a 
consistent approach to evaluating federal programs as part of the 
executive budget formulation process. It applies 25 questions to 
"programs" under four broad topics: (1) program purpose and design; (2) 
strategic planning; (3) program management; and (4) program results 
(i.e., whether a program is meeting its long-term and annual goals) as 
well as additional questions that are specific to one of seven 
mechanisms or approaches used to deliver the program. 

[28] GAO-05-757. 

[29] A form of this approach was first adopted by the Navy in the late 
1970s and most Coast Guard "condition based maintenance" capability is 
derived from proven Navy programs. According to Coast Guard officials, 
the Coast Guard is in the process of evaluating what other assets and 
systems for which such a maintenance approach may be effective. They 
stated that this approach is not a replacement for preventative 
maintenance work but is intended to complement it. 

[30] GAO, Coast Guard: Comprehensive Blueprint Needed to Balance and 
Monitor Resource Use and Measure Performance for All Missions, GAO-03-
544T (Washington, D.C.: Mar. 12, 2003); and GAO, Coast Guard: Strategy 
Needed for Setting and Monitoring Levels of Effort for All Missions, 
GAO-03-155 (Washington, D.C.: Nov. 12, 2002). 

[31] The scope of this proposal considered rehabilitating or replacing 
the following asset types: 21-foot trailerable aids-to-navigation 
boats; 45-foot buoy boats; 55-foot aids-to-navigation boats; 63-foot 
aids-to-navigation boat; 72-foot cable laying boat; 65-foot and 75-foot 
river buoy tenders; 65-foot small harbor tugs; the 65-foot and 100-foot 
inland tenders; the construction tenders (75-foot, 100-foot, and 160- 
foot); and the 140-foot icebreaking tugs. 

[32] These life-cycle costs include costs associated with planning and 
design, procurement, management and use, and disposal of the assets at 
the end of their service lives. We did not assess the reasonableness of 
the estimates provided in this analysis. 

[33] These boats can be placed on trailers and transported on land by 
truck. 

[34] According to a Coast Guard official, the Coast Guard is purchasing 
these boats under a 5-year "indefinite delivery, indefinite quantity" 
contract that allows the Coast Guard to order as many boats from the 
vendor at any given time at a cost of $180,000 per boat. The official 
stated that this price includes delivery, spare parts, trailers, and 
crew training and that the Coast Guard's obligation under the contract 
was to purchase at least one boat, which it has already met. Currently, 
the Coast Guard has 24 more boats on order and expects to order a total 
of 80 over the course of the contract to replace its existing fleet. 
According to a Coast Guard official, the Coast Guard hopes to have all 
new boats in place by 2011. This official also stated that under this 
contract, other DHS agencies also have the option of purchasing up to 
20 boats of similar design. 

[35] This assessment was done using OMB's Program Assessment Rating 
Tool (PART), which is a diagnostic rating tool meant to provide a 
consistent approach to evaluating federal programs as part of the 
executive budget formulation process. The assessment of the ATON 
program was completed in 2002. 

[36] According to Coast Guard officials, a limited amount of ATON work 
is currently contracted out in cases where the capabilities are needed 
only occasionally or the work cannot be done by the Coast Guard's 
assets. For example, in the aftermath of Hurricane Katrina, some ATON 
work was contracted to commercial providers that fixed navigational 
aids in waters too shallow for the Coast Guard's construction tenders 
to reach. 

[37] BearingPoint, United States Coast Guard Aids to Navigation 
Business Case Analysis, April 2004. 

[38] This study was commissioned by OMB in July 2006 and directed the 
Coast Guard to provide a conceptual analysis regarding ATON assets 
operating in the Western Rivers Waterways System. To accomplish this 
directive, the Coast Guard conducted an economic analysis of the Coast 
Guard's inland construction tender and river buoy tender assets. 

[39] Due to a lack of data, we did not perform this analysis for the 72-
foot cable laying boat.
