You will need to have your diving safety management system accepted by the agency if you intend to carry out offshore petroleum related diving operations as a diving contractor.
Diving contractors conduct diving projects for their clients, which comprise diving operations in which hazard, risk and health place safety matters are identified. Diving operations are a type of offshore petroleum operations that comprise one or more dives relating to the exploration, recovery, processing, storage, offloading or piped conveyance of petroleum.
