Offshore
Structures
![A few examples of offshore rigs, drilling and production platforms](Assets/Photos/abb.jpg)
A few examples of offshore rigs,
drilling and production
platforms.
Left to right: onshore platform; fixed
platform; jackup rig;
semi-submersible;
drill ship; tension leg platform. |
There are
approximately 4,000 production
facilities on the Outer Continental Shelf (OCS). These structures are
susceptible to corrosion,
fatigue,
damage caused by dropped objects, extreme
storms, and contacts from vessels. The integrity (condition) of older
platforms must be maintained. To ensure the safety and integrity of existing
structures, improved inspection and monitoring systems need to be devised
for platforms. The MMS, through the Technology Assessment and Research
(TA&R) Program, is working with the industry to assess and improve these
systems.
Exploratory wells
have been drilled at depths in excess of 10,000 feet. Production systems are being designed for depths of
6,000 feet and greater. The product pipeline networks for gas and oil will extend well off
the continental slope. Large reservoirs serviced by tension leg platforms or spar
platform derivatives will be operated by a consortia of companies and have extended
capability to handle distant subsea completions. Smaller reservoirs will use small moored
floating platforms for production, many of which will be reusable in other locations. The
business climate will demand innovative platform configurations, reductions in the weight
and cost of risers and mooring systems and solutions to the pipeline reliability problems.
As more reserves are being discovered in deep
water, the technology needed to design and build deep-ocean compliant
structures, such as tension leg platforms, continues to evolve to meet
technical and economic needs for deepwater development. This rapid evolution
in technology needs to be independently verified to ensure continued safety
of operations and protection of the environment.
Recent interest in exploration and development on the
Alaskan-area OCS has led to a need for new research to ensure the Best
Available and Safest Technologies are utilized in this expanding frontier.
A complete list of projects MMS TA&R Project has undertaken
pertaining to structural issues is outlined below. Double-clicking on the
number will bring up more information on the project.
