Qualifying near coastal sea service

How to calculate, record and provide your sea service for your certificate of competency.

Qualifying sea service requirements are set out in the National Standard for Commercial Vessels Part D—Crew competencies (NSCV Part D).

NSCV Part D contains information on: 

  • Calculation of qualifying sea service
  • Recognition of other types of service
  • Equivalence in service
  • Evidence
  • Discounting service
  • Definitions 


An applicant may provide AMSA with evidence of sea service in the following ways: 

There may be circumstances where an applicant is unable to get a supervisor signature on the Record of sea service (form 771). This includes, for example, circumstances where the vessel operator no longer exist. In such circumstances, we may accept that the Record of sea service is attached with a Statutory Declaration. In the Statutory Declaration, the applicant declare that the information provided in the Record of sea service is true. The applicant must also provide a justification why we should accept a Statutory Declaration instead of a supervisor signature.

It is an offence to make a statement that is false or misleading in an application for a certificate.

Recognition of other types of service 

AMSA may recognise qualifying sea service, in capacities or trades or on kinds of vessels that are not recognised by NSCV Part D. Such service could, for example, include service on defence vessels. 

Recognition of sea service not recognised by NSCV Part D is done on a case-by-case basis according to its equivalence to the following:

  • The duration and frequency of voyages.
  • The kind of duties performed and their duration and frequency.
  • The level of responsibility during the service.
  • The relevance of the service to the certificate of competency applied for. 

An applicant should provide details and evidence of such service in their application.

We make decisions about seafarer certificates under Marine Order 505 (Certificates of competency — national law) 2013 and the National Standard for Commercial Vessels Part D—Crew competencies.
