Audit Information

To support its mission, the Center for Offshore Safety (COS) has developed a strategy for promoting safety and protection of the environment. This strategy includes third party auditing and certification of the COS member company’s safety and environmental management system (SEMS) and accreditation of the organizations (Audit Service Providers) providing the audit services. The third party audits are performed to ensure that COS member companies are implementing and maintaining a safety and environmental management system (SEMS) throughout their U.S. OCS with Offshore operations.

COS procedures for Auditing and Certification (COS-2-03) define how an ASP audits an organization's SEMS and determines when a certificate can be issued. Organizations that have been certified by COS and their ASP are found at:
