Assessment of Existing OCS Platforms

MMS Requirement – NTL 2003-G16
|
Published on February 19, 2004
Summary
MMS (GOMR) has determined that each existing OCS platform in the Gulf of Mexico that has been in
service for more than five years must now undergo an assessment in accordance with API RP 2A-WSD,
section 17, 21st Edition. This assessment will help to ensure the integrity of platform structures in the
Gulf of Mexico, which are a strategic national asset. The assessment process is primarily conc erned
with the platform’s ability to survive wind, wave and current conditions based on the 100-year design
criteria.
Deadline
The initial phase of the assessment process, due by June 1, 2004, involves determining the exposure
category of the platform, and evaluating if there have been changes to the platform that trigger further
analysis. If further analysis is required, a review of the platform’s design and/or an ultimate strength
analysis must be completed by June 1, 2005 or June 1, 2006. If the platform fails this analysis,
mitigation or abandonment of the platform will be necessary. All analysis and mitigation of analysis
failures must be completed by November 1, 2006. See Table 1 for more detail on the requirement
deadlines.
Requirement in the Initial Phase
Platform operators are required to assemble platform, well and pipeline information for each offshore
facility, determine the platform’s exposure category and submit a completed OSTS Assessment Report
to the regional MMS office. MMS has developed a specific Excel-based spreadsheet format for this
purpose. (Though the reporting requirement and deadline are in effect, they may be subject to the
rulemaking process, and JCC will carefully monitor the resulting rule and adjust our services if
necessary).
