General Requirements, STCW Certificates, Endorsements & Training Required for Able Seafarer Deck (AS-D)

able seaman deck

Transitioning from Able Seaman or AB, the Able Seafarer Deck (AS-D or AB Deck) is a new STCW endorsement and is a qualified rating at the deck department on ocean going vessels of 500 GT or more. AS-D certificate corresponds with a certificate issued under STCW regulation II/5 of the STCW Convention as amended in 2010. With this certificate, you can perform the functions and duties of a deck rating forming part of a navigational watch on ocean going vessels.

An AS-D may work as a watchstander, a day worker, or a combination of these roles and, must be able to work safely in enclosed spaces and at heights, and must also be able to respond to vessel emergencies, administer emergency first aid, carry out fire prevention and fire-fighting duties, be able to use survival techniques in the water, and be able to operate survival craft and rescue boats to name a few of the duties involved.

The AS-D is considered a higher endorsement than the RFPNW; however, by itself RFPNW will not qualify you for an AS-D endorsement. An Able Seaman (AB) is a rating of the deck department and they can transition into an AS-D with seagoing experience and subject to other conditions which varies at different maritime administrations. With STCW 2010, onboard a seagoing vessel of 500 GT or more, AS-D has become mandatory (except for training).
