The offshore oil and gas industry had developed the Safety and Environmental Management Program (SEMP) in 1993. The SEMP program, which is a process safety-like program, was published in API-RP 75. This program, which has been incorporated into the current SEMS regulations by reference, was voluntary and not adopted or enforced by the primary government agency responsible for regulating offshore oil and gas exploration and production operations, the Minerals Management Service (MMS) of the Department of the Interior. MMS has since been replaced by the Bureau of Ocean Energy Management Regulation and Enforcement (BOEMRE), which has subsequently been split into three agencies: Office of Natural Resources Revenue (ONRR), Bureau of Ocean Energy Management (BOEM), and Bureau of Safety and Environmental Enforcement (BSEE). BSEE has responsibility for enforcing the new SEMS regulations.
