Summary of Findings
The Master Item Table which appears below lists each of the Key
Areas assessed. A number of Key Areas were divided into sub areas. The Key
Areas were also divided into three groups—Pipeline (continuous transport), Transport
(discrete transport), and Crosscut (areas which affect both pipeline and
transport). The Crosscut group largely dealt with material and environmental
issues, such as embrittlement, strength and fatigue, pressure and temperature,
etc.
A total of 86 Key and Sub Areas items were assessed. This number
fluctuated somewhat as the effort progressed as new items were identified or
eliminated and existing items were subdivided or consolidated. Of the 86 items,
8 are Crosscut, 47 Pipeline, and 31 Transport.
In terms of criticality, 64 items are assessed High, 21 Medium,
and 1 Low. These are divided across the groups as shown in Figure 4. All of the Crosscut items are assessed as High, largely
because material and environmental issues potentially impact a number of
transportation technologies. Several Low items were dropped from the analysis
at an early stage as their combination of Low criticality and level of progress
yielded low scores which did not warrant further effort.
In terms of progress, 37 Key Areas have progress assessments of
Not Addressed, 47 Addressed, Not Adequately, and 2 Addressed, Monitoring. These
are divided across the groups as shown in Figure
5. Most of the Crosscut items have
progress assessments of Addressed, Not Adequately as there are a number of
material and environmental efforts underway but most are in their early stages
or are just getting underway. The Pipeline group is more evenly divided between
Not Addressed and Addressed, Not Adequately while Transport has fewer Not
Addressed compared to Addressed, Not Adequately.
The distribution of scores—the product of the weights of criticality
and progress—is shown in Figure
6. There are 29 scores of 40, 8
scores of 24, and 33 scores of 20. A score of 40 represents a combination of
High criticality and progress of Not Addressed. A score of 24 represents a
combination of Medium criticality and progress of Not Addressed. A score of 20
represents a combination of High criticality and progress of Addressed, Not
Adequately.
The Pipeline group has the highest number of 40 scores, also
representing the largest Key Area count for the scores both within the Pipeline
and overall. The Crosscut group is mostly 20 scores, reflecting the progress
assessment distribution for those items. For Transport, nearly half the items
have 20 scores (High criticality and progress of Addressed, Not Adequately) as
these items tend to be areas where applicable safety practices could be adapted
to new transport technologies.
In terms of timeframe, 62 Key Areas have assessments of 0 to 5
years and 24 of 5 to 15 years. These are divided across the groups as shown in Figure 7. All the Crosscut items are short term while 60% to 80% of
the Pipeline and Transport items, respectively, are short term. Most short term
needs are either because the technologies are currently or shortly being
deployed or because there is a long lead-time anticipated for development of
safety practices for the item.
Examining the combination of score and timeframe, the
distribution of items appears in Figure
8. There are 20 items in the short
term with scores of 40, 3 items with scores of 24, and 29 items with scores of
20. The short term items with scores of 40 appear in Table 1,
those with scores of 24 appear in Table
2, and those with scores of 20
appear in Table 3.
The average score within each group are approximately equal, with
the average for Crosscut at 25, Pipeline at 27, and Transport at 23.
Specific recommendations are found in each Key Area Item
Assessment. The Master Item Table below identifies each item with its criticality
and progress assessments.
