STCW Certificates and Requirements for Officer in Charge of a Navigational Watch (OICNW) on Ocean Going & Near Coastal Ships
Officer in Charge of a Navigational Watch (OICNW) is a Certificate of Competency (CoC) and 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.
Some example of OICNW endorsements would be Chief Mate, Third Mate (Third officer), Second Mate (Second Officer), Mate, Mate (Pilot) etc.
The STCW regulations do not apply to vessels inland, seagoing vessels below 200 GRT, and uninspected vessels. This endorsement is based on required training, sea-time and assessments.
For example, the chief mate typically stands the 4-8 navigation watch as OICNW directing the bridge team. The Second officer/Second mate is a qualified OICNW watch stander, directing the bridge team and navigating the ship. The Third Officer or Third Mate is the least experienced qualified OICNW watch-stander and, on navigational watch, the Third Mate directs the bridge team,maneuvering the vessel, keeping it safe and on track.
