USCG OICNW STCW Requirements - Merchant Mariner Credential


U.S. Coast Guard Requirements (General, Sea Service, Training & Other) for OICNW STCW Endorsements


Officer in Charge of a Navigational Watch (OICNW) is an STCW endorsement with tonnage limitations for the deck officer on a sea going merchant ship. The tonnage limitations are either 500 gross tonnage or more and, less that 500 GT but above 200 GT.

The OCINW is under a master’s command and so the duties are assigned by the master or captain of the ship. STCW regulations apply to seagoing vessels greater than 200 GRT and higher and these regulations do not apply to vessels operating exclusively on the Inland waters of the United States; seagoing vessels of less than 200 tons; and uninspected passenger vessels.

The OICNW duties consist (not limited to) of the duties of a National Mate credential.
