Norway Deck Officer Class 1 (Master Mariner)

It is the management-level deck certificate that qualifies you to serve as master on seagoing ships without tonnage or trading-area limitation, subject to any endorsements and to the flag state requirements of the ship you join. In practice it is the document employers ask for when appointing a master or a senior chief officer.

The Norwegian system uses written examinations, typically with multiple-choice sections and longer answer papers, followed by an oral examination. The exact mix, the number of papers and whether any part is digital are set by the Norwegian Maritime Authority and can change, so check its current examination information before you plan your study.

Those details are set by the Norwegian Maritime Authority and are published on its website together with the current examination timetable. They are not fixed for all time, so confirm the current figures directly with the authority rather than relying on what earlier candidates experienced.

Fees and the pass requirement are set by the Norwegian Maritime Authority and published on its site. Because they are revised periodically, check the current fee schedule and the current regulations for the pass criteria before you submit an application or budget for the examination.

Retake arrangements, waiting periods and any limit on the number of attempts are governed by the authority's regulations and are published by it. Candidates can normally resit individual papers rather than the whole examination, but confirm the current rule and the registration deadlines with the authority before booking.

The step up is mainly in breadth and in the standard of explanation expected. Lower certificates test that you can apply procedures; Class 1 tests that you can justify decisions as the person in command, including in stability, legal and human-factors scenarios where more than one answer looks defensible. Written answers must show the reasoning, not just the conclusion.

Start with the quantitative core: navigation and position determination, stability and construction, and machinery systems, because these underpin later subjects and take longest to become fluent in. Then work through ship handling, collision regulations and bridge procedures, cargo and dangerous goods, and law. Leave human factors and ships business for later, when you can link them to the technical material.

Weak arithmetic under time pressure in navigation and stability, answers that state a result without showing the working, and shallow knowledge of maritime law and flag state administration. In the oral, candidates often fail by guessing instead of reasoning aloud, or by not structuring an answer. Practise explaining a decision step by step before you defend it.

Most candidates need several months of part-time study alongside watchkeeping, longer if their mathematics or stability knowledge is rusty. Build in time for full timed written practice and at least a few mock orals with an experienced master or a study group, since the oral format is where prepared knowledge most often breaks down.

Yes. The certificate is competence-based, so approved education and documented seagoing service in a deck officer role are prerequisites. The current combinations of education, service time and any exemptions are set out by the Norwegian Maritime Authority, and you should have your documentation assessed before starting examination preparation.
