Companies with SEMS Certificates

COS SEMS Certificates differentiate companies that have committed to meeting their operational safety, environmental, and sustainability goals by adopting a Safety and Environmental Management System and having it audited by an independent COS-accredited ASP.

Many offshore energy operations have obtained and maintain a COS Safety and Environmental Management System (SEMS) certificate, demonstrating their commitment to the highest standards for safety and environmental protection.

These organizations have satisfactorily completed a SEMS audit against API Recommended Practice 75 for Safety and Environmental Management Systems, which is incorporated into BSEE's regulatory requirements, conducted by a COS-accredited Audit Service Provider (ASP), and closed necessary corrective actions in accordance with COS requirements.
