Marine Casualty Reporting on the Outer Continental Shelf

This final rule revises marine casualty reporting criteria for Outer Continental Shelf (OCS) activities to focus on characteristics of the involved entity rather than location of the casualty. It also raises the property damage dollar threshold (PDT) for reporting marine casualties involving fixed OCS facilities from $25,000 to $75,000 and aligns other OCS units with that threshold, consistency with the PDT for vessels in U.S. waters. The rule reduces costs to U.S. industry by $10,775 over 10 years and better harmonizes reporting requirements between U.S. and foreign floating offshore facilities, mobile offshore drilling units, and vessels engaged in OCS activities.
