Merchant Navy (B.Sc Nautical Science / B.Tech Marine Engineering) in India — eligibility, exams, fees, careers

The merchant navy runs the world's cargo ships, tankers and container vessels; it is commercial shipping, not the Indian Navy. After Class 12 you train either as a deck officer (navigation, cargo, ship handling) through Nautical Science, or as an engine officer (running and maintaining the ship's machinery) through Marine Engineering. Training is regulated by the Directorate General of Shipping (DG Shipping). It suits fit, adaptable students who can live at sea for months at a time.

Know this. Finishing the course is only half the job; you need a ship to complete sea time before you can take the licence exam, and getting that first berth is the real bottleneck. Many private institutes sell 'guaranteed placement' that does not materialise. Prefer an IMU campus, a well-known institute with a published record, or a company-sponsored cadetship, and check the medical and eyesight standards before spending anything.

Getting in

Pre-sea training for the Merchant Navy: B.Sc (Nautical Science), Diploma in Nautical Science, and B.Tech / B.E. (Marine Engineering)

Who can apply

Class 12 (or equivalent) with an average of at least 60% in Physics, Chemistry and Mathematics, and at least 50% in English in Class 10 or Class 12, plus a valid IMU-CET rank. Candidates must be unmarried. Maximum age on the date the session begins: men 25 (OBC-NCL 28, SC/ST 30); women 27 (OBC-NCL 30, SC/ST 32). SC/ST candidates get 5% relaxation in the PCM marks. You must be medically fit under the Merchant Shipping (Medical Examination) Rules, with eyesight and colour-vision standards (for nautical science, unaided distance vision of 6/6 in the better eye and 6/9 in the other, and normal colour vision), certified by a DG Shipping approved doctor.

How admission works

IMU-CET, conducted by the Indian Maritime University (a central university) once a year, usually in May, is compulsory for all DG Shipping approved pre-sea courses. Under DG Shipping's training circular, every maritime training institute, government or private, must admit Nautical Science, Diploma in Nautical Science and Marine Engineering students on the basis of IMU-CET ranks. For IMU's own campuses (Chennai, Kolkata, Mumbai, Navi Mumbai, Kochi, Visakhapatnam) you register on IMU's counselling portal after the rank list comes out in June; allotment lists and spot rounds follow in July–August. For affiliated and other approved institutes, you take your IMU-CET rank to each institute and follow its own admission process. The one-year Diploma in Nautical Science is open only to candidates sponsored by a shipping company. Some shipping companies also sponsor cadets for the degree and run their own tests and interviews.

Duration: B.Sc Nautical Science 3 years; B.Tech Marine Engineering 4 years; Diploma in Nautical Science 1 year (sponsored). All are followed by months of sea time as a cadet before the first officer's licence exam.
Entrance: IMU-CET

What you study

Nautical Science: navigation (terrestrial, celestial, electronic), ship stability and construction, cargo work, meteorology, seamanship, maritime law and collision regulations
Marine Engineering: thermodynamics, marine diesel engines, steam and auxiliary machinery, electrical and control systems, ship structure, workshop training
Both: STCW basic safety courses (fire fighting, sea survival, first aid, personal safety), physical training and a disciplined residential routine
After the course: sea time as a deck or engine cadet on a ship, then DG Shipping exams for the first Certificate of Competency (for example Second Mate or Class IV engineer)

Specialisations: Deck side: B.Sc Nautical Science or Diploma in Nautical Science · Engine side: B.Tech / B.E. Marine Engineering · Related shore-based: B.Tech Naval Architecture and Ocean Engineering (IMU-CET), BBA in shipping and logistics

Is it you?

A good fit if

You are physically fit and meet the eyesight and colour-vision standards
You can handle long periods away from home, often four to nine months at a time
You like hands-on, practical responsibility and working in a small team
You want tax-efficient international pay early in your career and are prepared to earn it

Think twice if

You have a colour-vision defect or eyesight below the standard (check before paying any fee)
You struggle with isolation, limited internet and being away for festivals and family events
You get seriously seasick or dislike confined living
You or your family cannot bear the risk of a delay in getting the first ship after training

The honest part

Months at sea with limited contact; relationships and family events suffer
Shipping is cyclical; hiring and pay fall when freight markets are weak
Fraudulent agents and 'placement' institutes target merchant navy aspirants; verify DG Shipping approval
Promotions require passing further DG Shipping competency exams and accumulating sea time
Many seafarers move ashore in their 30s, often to lower-paid but steadier jobs

What it costs

Government: IMU campuses charge moderate tuition plus compulsory residential costs; total roughly ₹2–4 lakh a year
Private: Private maritime institutes typically charge roughly ₹3–8 lakh a year including hostel, uniform and mandatory short courses
Help: Company-sponsored cadetships often cover part or all of the training cost and guarantee sea time, which is the most important thing for a new cadet. IMU offers some scholarships, including special ones for women cadets. Budget separately for STCW courses, medicals and CDC/INDoS documentation.

Rough 2026 ranges to compare routes. Fees differ by college and state and change every year.

After this

Study next

Or start work as

Deck cadet, then Third Officer / Second Officer, Chief Officer and Master (Captain) on cargo, tanker, container and offshore vessels
Engine cadet (trainee marine engineer), then Fourth / Third / Second Engineer and Chief Engineer
Shore jobs after sea experience: marine superintendent, port captain, surveyor with classification societies, marine insurance, ship management and chartering
Harbour and river pilot, and instructor at maritime training institutes

Starting pay

Cadets on their first ship earn a modest stipend, roughly ₹25,000–70,000 a month depending on the company. After the first Certificate of Competency, junior officers typically earn roughly $1,500–4,000 a month on international ships, and senior officers (Chief Officer, Chief Engineer, Master) considerably more. Pay is only for months at sea, varies with the shipping cycle and company, and is not paid during shore leave for many contract seafarers.

Questions families ask

Is the merchant navy the same as the Indian Navy?

No. The Indian Navy is a defence service recruited through NDA, CDS and other defence entries. The merchant navy is commercial shipping, and you work for private or public shipping companies.

Is IMU-CET compulsory even for private colleges?

Yes. IMU's prospectus quotes DG Shipping's training circular requiring all DG Shipping regulated maritime training institutes, government or private, to admit pre-sea Nautical Science and Marine Engineering students on the basis of IMU-CET ranking.

Can girls join the merchant navy?

Yes. IMU's eligibility rules set separate, higher age limits for women, and IMU offers special scholarships for women cadets. Numbers are still small, but they are growing.

Deck or engine, which should I choose?

Deck (Nautical Science) is about navigation, cargo and ship handling, leading to Captain. Engine (Marine Engineering) is about machinery, leading to Chief Engineer, and the B.Tech also gives you a degree that is useful ashore. Engine officers usually find shore jobs a little more easily.

What if I wear glasses?

Nautical science has strict unaided eyesight and colour-vision rules. Marine engineering is somewhat more relaxed but still has standards. Get tested by a DG Shipping approved doctor before applying.
