Offshore Supply Vessel (OSV) Endorsements

New regulations revise sea service requirements for deck and engine OSV endorsements making them comparable to other endorsements. Mariners with service or training before March 24, 2014, can qualify for National OSV endorsements by meeting previous regulations until March 24, 2019.

New wording for National endorsement of Engineer (OSV) is Assistant Engineer (OSV). This change will be made at the next Merchant Mariner Credential (MMC) transaction.
