About this exam

The Bangladesh Deck Officer Class 3 certificate is the Officer of the Watch (OOW) qualification for deck officers, issued through the Department of Shipping and the Mercantile Marine Office. It is the first certificate a cadet or rating aims for on the path to chief mate and master, and it certifies that the holder can stand a navigational watch safely, legally and without supervision. Candidates are typically cadets completing structured sea service, or ratings with approved watchkeeping experience, who must satisfy medical, sea-time and training requirements before sitting the examinations.

The assessment is broad rather than deep in any single subject. Written papers and orals test terrestrial and electronic navigation, the collision regulations and watchkeeping practice, ship construction and stability, cargo handling and stowage, meteorology, GMDSS communications, environmental protection, maritime law and conventions, emergency response and medical first aid. Examiners expect working knowledge that can be applied at sea, not memorised definitions, and oral examinations in particular reward candidates who can explain decisions clearly under questioning.

Preparation works best as a structured programme: master the collision regulations and basic navigation first, since they underpin most other papers, then build stability, cargo and meteorology around them, and finish with law, communications and emergency topics. Work through past-paper-style problems, practise chartwork and stability calculations by hand, and rehearse oral answers aloud. Question counts, time limits, fees and pass marks are set by the Department of Shipping and change from time to time; check its current notices rather than relying on second-hand figures.

What you'll study

Common questions

About BD Deck Officer Class 3 (OOW) preparation

What does the Class 3 Deck Officer certificate actually allow me to do?

It certifies you to stand a navigational watch as Officer of the Watch on seagoing vessels within the limits endorsed on your certificate. It is the foundation certificate for progression toward chief mate and master, subject to further sea service and examinations.

What is the examination format?

Expect a mix of written papers, multiple-choice and short-answer questions, practical chartwork and calculation exercises, and an oral examination before an examiner. The exact subject list and paper structure are published by the Department of Shipping, so confirm the current syllabus directly with them.

How many questions are on each paper and how long do I get?

These details are set by the Department of Shipping and are revised periodically, so no fixed figure should be relied on. Check the current examination notice on the Department of Shipping website, or ask your training institute, before planning your exam-day timing.

How difficult is the exam, and what is the pass mark?

Most candidates find the breadth demanding rather than any single topic: you must be competent across navigation, stability, cargo, law and emergency response at once. The pass mark and any subject-specific minimum are published by the Department of Shipping; confirm the current requirement with them.

If I fail a paper, can I retake it, and how soon?

Retake and referral arrangements are governed by the Department of Shipping's current examination rules, including any waiting periods or limits on the number of attempts. These rules change, so obtain the current policy in writing from the Mercantile Marine Office rather than relying on what other candidates tell you.

In what order should I study the subjects?

Start with the collision regulations and basic terrestrial navigation, because they appear inside other papers and in the oral. Then take stability and ship construction, followed by cargo handling and meteorology. Finish with maritime law, GMDSS and emergency and medical topics, which are easier once the operational subjects are solid.

Why do candidates fail the oral examination?

Usually not from ignorance but from being unable to explain a decision. Examiners probe practical scenarios: what you would do, why, and what you would tell the master. Practise answering aloud, justify each action with a regulation or principle, and admit uncertainty honestly instead of guessing.

How much sea service do I need before sitting?

Approved sea service, watchkeeping time and course completion requirements are specified by the Department of Shipping and depend on your entry route as cadet or rating. Verify your sea-time records against the current requirements early, because shortfalls discovered late are the most common cause of delay.

Where can I confirm fees, dates and certificate validity?

Only the Department of Shipping and the Mercantile Marine Office publish authoritative figures for fees, examination dates, result procedures and certificate validity. Use their official website or office counter, and keep copies of every receipt and notice for your records.
