About SEMS Certificates

The Center for Offshore Safety promotes Safety and Environmental Management Systems which deliver safe and reliable operations and operational integrity.

The Center for Offshore Safety (COS) plays a critical role in SEMS audits by accrediting qualified third-party Audit Service Providers (ASP), that audit an operator’s SEMS and its implementation at their facilities  in accordance with COS-2-03, API RP 75 and the U.S. Bureau of Safety and Environmental Enforcement’s (BSEE) SEMS requirements. 

Upon completion of a SEMS audit by an independent COS-accredited ASP, and resolution of necessary corrective actions, operators can receive a certificate demonstrating that they meet the requirements of COS and API Recommended Practice (RP) 75.

Drillers, Contractors, and Other Service Providers

Only OCS Operators are regulatorily required to conduct SEMS audits and implement SEMS; however, drilling contractors, offshore service providers, and other contract organizations must work within an operator’s SEMS, and can be part of an operator’s SEMS audit. Additionally, many contractors voluntarily implement SEMS. The accredited ASPs may also independently audit their SEMS.

SEMS certificates are available to drilling contractors, offshore service contractors, and supply companies who have a SEMS audit completed by an accredited ASP and resolve findings through appropriate corrective action.
