This project would revise and update the Coast Guard's commercial diving regulations, which were first adopted in 1978. These revisions and updates would reflect current industry best practices, and new procedures and requirements would allow the Coast Guard to approve independent third party organizations to assist with ensuring regulatory compliance. The project supports the Coast Guard Maritime Safety, Security, and Stewardship program's role and responsibility of reducing deaths and injuries on U.S. commercial vessels, and the Coast Guard's broad role and responsibility of maritime safety.
