- A ship's bridge at sea, in contracts of six to nine months, with shore leave between Watch-keeping shifts around the clock, every day of a contract
Overview
Understand the role
The deck officer navigates the ship, plans and secures the cargo, and takes responsibility for the safety of both. The ladder ends at Master, which on a merchant ship is the final authority.
What the work involves
Day to day
Bridge watch-keeping, passage planning and position fixing, cargo loading and stability calculation, port documentation, and drills and inspections against international safety regulation. On a modern ship a great deal of it is compliance work as well as seamanship.
Who should choose it
Fit
People who are comfortable holding responsibility alone at three in the morning. Progression is unusually predictable — sea time plus a competency exam moves you up regardless of who likes you — and the earnings at senior rank are high for a three-year degree.
The reality of the job
Read this one
Long contracts, disrupted sleep, and months without seeing anyone you know. Eyesight and colour vision standards are strict and non-negotiable, so test before you invest. Responsibility is real: errors on a bridge cost lives and cargo, and the industry treats them accordingly. Shore careers in pilotage, port operations, surveying and chartering follow for those who stop sailing.
The route in, step by step
6 steps from where you are now.
Class 12 with Physics, Chemistry and Mathematics Required
PCM, with the eyesight and medical standards met.
Complete a DG Shipping approved nautical course and cadetship Required
B.Sc Nautical Science or DNS, then twelve to eighteen months of sea service as a cadet.
Pass the Second Mate Certificate of Competency Required
Written and oral examinations with the Mercantile Marine Department. This makes you a Third Officer and is the real entry to the profession.
Sail as Third, then Second Officer Required
Navigation watchkeeping, cargo work, safety equipment and passage planning. Contracts run four to eight months with leave between.
Sit the Chief Mate Certificate of Competency Required
Requires documented sea service at the rank below. Each CoC has its own service requirement, so track your sea time carefully from the first day.
Master Certificate of Competency, then command Optional
The Master CoC, then sailing as Captain. Ten to fifteen years from cadet to command is typical. Shore roles in operations, survey and port management are the alternative exit.

Common questions
The ones people actually ask about this work.
How do I become a deck officer?
<p>Through the Diploma in Nautical Science or a B.Sc Nautical Science at a DG Shipping approved institute, usually entered via IMU CET, then joining a ship as a deck cadet. Sea time and the certificate of competency examinations take you from cadet to third mate and upward towards master.</p>
What does a deck officer do?
<p>Navigates and handles the ship, keeps bridge watch, manages cargo operations and stability, oversees safety and security, and handles port documentation. As you rise, more of the job becomes management of people, cargo and compliance rather than navigation itself.</p>
Is getting a cadetship difficult?
<p>It is the real bottleneck, and it catches students out. Completing the course does not guarantee a shipping company will take you as a cadet, and without sea time you cannot progress. Ask any institute, before enrolling, what proportion of the last two batches actually got a cadetship and with which companies — and be sceptical of an answer that comes without names.</p>
How long until I command a ship?
<p>Many years, through each rank and each certificate of competency, with the required sea time at every stage. It is a defined, well-understood ladder rather than a vague one, but it is measured in a decade and more rather than a few years.</p>
