National Policy

National policy letters that apply to floating OCS facilities are listed in the table below, grouped by issuing authority and ordered from newest to oldest (by policy number/original issue date). Click on the policy number to open the document (opens in a new window).

February 2022 Policy Change: Please review CG-OES PL 01-22 and CG-MMS PL 01-22 in conjunction with 87 FR 7716 published on February 10, 2022 for a shift from the way that the CG has historically treated FOFs as "vessels". These policies discuss guidance on determining if a FOF is a vessel or non-vessel, oversight, certification/documents issued, manning requirements and changes related to merchant mariner credentials issued for service on FOFs. These policies came from a multi-year internal review of the USCG's regulations, policies and procedures related to oversight of FOFs on the U.S. OCS. The CG also reviewed recent court rulings related to OCS activities and the 2018 NOSAC report detailing the review and recommendations for CG regulations applicable to OCS units operating on the U.S. OCS (Production Subcommittee Final Report) while developing these policies.

District Eight (Gulf of Mexico) Policy

D8 policy letters that apply to floating OCS facilities are listed in the table below, grouped by issuing authority and ordered from newest to oldest (by policy number/original issue date). Click on the policy number to open the document (opens in a new window).

Inspection Job Aid

The following Job Aid pertains to Floating OCS Facilities on the U.S. Outer Continental Shelf. Job Aids replaced the legacy CG-840 Books and can be a valuable tool for owners and operators to maintain regulatory compliance on their facilities.

• Floating OCS Facility Job Aid: standard format or booklet.

Notes: 

Job Aids are developed for use by the CG Marine Inspector, following internal CG procedures, and are provided as a convenience (and transparency) to industry. The Pre-Inspection/Pre-Exam and Follow-Up sections mainly pertain to administrative tasks of the Marine Inspector. While "if applicable" is NOT annotated within the Job Aid, there are inspection/exam items listed that may not apply to a particular facility.

Additional Job Aids and Marine Inspector Performance Qualification Standards (PQS) are available on CVC's MI Resources page.
