What Is the Merchant Navy?
The merchant navy refers to commercial ships that carry cargo and passengers, unlike the Indian Navy, which is a defence force. Merchant ships include container ships, oil and chemical tankers, bulk carriers, LNG and LPG carriers, car carriers, offshore vessels and cruise ships. These ships are owned or managed by shipping companies around the world, and they employ seafarers from many countries, including India.
India is one of the largest suppliers of trained seafarers. Indian officers and engineers are respected for their skills and English communication. A career at sea offers responsibility at a young age, as officers handle navigation, cargo operations and machinery worth millions of dollars.
Departments on a Ship
Deck department
The deck department handles navigation, cargo operations, safety and ship maintenance on deck. Officers start as a deck cadet and progress to Third Officer, Second Officer, Chief Officer and finally Master, also called Captain. Ratings in the deck department, such as Ordinary Seaman and Able Seaman, support officers in watchkeeping and maintenance.
Engine department
The engine department operates and maintains the main engine, generators, boilers, pumps and other machinery. Marine engineers begin as trainee or junior engineers and move up to Fourth, Third, Second and Chief Engineer. Electro-technical officers handle electrical and electronic systems. Engine ratings like wipers and oilers assist engineers.
Catering and service department
Cooks, stewards and, on cruise ships, hospitality staff provide food and services. Cruise lines also hire staff in housekeeping, entertainment, retail and guest services, which is a different career path from cargo shipping.
Entry Routes into a Merchant Navy Career
| Route | Eligibility | Leads To |
|---|---|---|
| GP Rating course | Usually Class 10 or 12 with required marks | Deck or engine rating |
| Diploma in Nautical Science | Class 12 with Physics, Chemistry, Maths and English | Deck cadet, then officer |
| B.Sc Nautical Science | Class 12 with PCM and English, entrance test | Deck cadet, then officer |
| B.Tech Marine Engineering | Class 12 with PCM, entrance test | Trainee marine engineer |
| Graduate Marine Engineering | Degree in mechanical or allied engineering | Trainee marine engineer |
| Electro-Technical Officer course | Degree or diploma in electrical or electronics | Electro-technical officer |
Exact marks, age limits and eligibility differ between courses and institutes. Check the latest admission notice of the Indian Maritime University or DG Shipping-approved institutes before applying.
Becoming a Deck Cadet
Most deck officers start as a deck cadet. After completing a pre-sea course such as B.Sc Nautical Science or DNS, cadets join a ship for onboard training. During this period, they learn watchkeeping, navigation equipment, cargo work, mooring and safety drills under senior officers. Cadets maintain a training record book that documents their tasks.
After the required sea time, cadets attend further courses ashore and take written and oral examinations conducted under DG Shipping to obtain a Certificate of Competency as a Second Mate or officer in charge of a navigational watch. This certificate allows them to work as Third Officer or Second Officer.
Marine Engineering Path
Marine engineering offers two main routes. Students after Class 12 can join a four-year B.Tech Marine Engineering programme, which includes workshop and onboard training. Mechanical engineering graduates can join a one-year Graduate Marine Engineering course approved by DG Shipping. After the course and required sea service, engineers take competency exams to become Fourth or Third Engineer.
Engineers progress through Class IV, Class II and Class I certificates. A Class I certificate qualifies them to serve as Chief Engineer, the senior-most engineering position on board. Marine engineering skills are also valued ashore in ship management, surveying, classification societies and ports.
IMU CET and Admissions
The Indian Maritime University conducts the IMU CET for admission to many undergraduate and postgraduate maritime courses at its campuses, including Kochi, and at affiliated institutes. The test usually covers English, general aptitude, physics, chemistry and mathematics. Candidates also need to meet medical and eyesight standards for sea-going courses.
Prepare for IMU CET using Class 11 and 12 physics, chemistry and maths, along with basic aptitude and English. Our guide to aptitude test preparation and time management for competitive exams can help.
Medical and Eyesight Standards
Seafarers must be medically fit. DG Shipping-approved doctors conduct medical examinations covering general health, hearing and eyesight. Deck officers typically need good eyesight without colour blindness, as they must identify navigation lights. Engine officers have some flexibility, but standards still apply. Check medical requirements before paying admission fees, because failing the medical later can end your plans.
Important Documents for Seafarers
- INDoS number: Indian National Database of Seafarers registration, required for courses and jobs.
- CDC: Continuous Discharge Certificate, the seafarer’s identity and service record book.
- Passport: valid passport for joining ships abroad.
- STCW certificates: basic safety training such as personal survival, fire fighting, first aid and security awareness.
- Certificate of Competency: for officers and engineers after exams.
- Medical fitness certificate: from an approved doctor.
- Seafarer identity documents: as required by current rules.
Salary in the Merchant Navy
Salaries in the merchant navy are higher than many shore jobs, especially at senior ranks. Cadets and trainees receive a stipend, which is modest. After certification, officers and engineers earn significantly more, and senior officers like Captains and Chief Engineers can earn very high monthly wages on international ships. Salaries vary by ship type, company, flag and experience. Tankers and LNG carriers usually pay more than general cargo ships.
| Rank Level | Salary Trend |
|---|---|
| Deck cadet or trainee engineer | Stipend during training |
| Third Officer or Fourth Engineer | Good entry-level salary |
| Second Officer or Third Engineer | Higher salary with experience |
| Chief Officer or Second Engineer | Senior management level pay |
| Captain or Chief Engineer | Highest pay on board |
Seafarers who spend a minimum number of days outside India in a financial year may qualify as non-resident for income tax purposes, subject to tax rules.
Life at Sea
Life at sea is rewarding but demanding. Contracts typically last several months, followed by leave at home. Officers work in watches and handle long hours during port operations. Ships are workplaces with strict safety rules and hierarchy. Internet connectivity has improved on many ships, making it easier to stay in touch with family, but long periods away from home remain a challenge.
Successful seafarers are disciplined, physically fit, good at teamwork and calm in emergencies. Before choosing this path, talk to working seafarers about the realities of life on board.
How to Avoid Fake Agents and Institutes
Unfortunately, the merchant navy attracts many fraudulent agents who promise jobs on ships in exchange for large fees. Some unapproved institutes also run courses that are not recognised. Protect yourself with these checks:
- Verify that the institute and course are approved by DG Shipping.
- Check that recruitment agencies hold a valid RPSL licence from DG Shipping.
- Do not pay large amounts for job placement; reputed companies hire through approved channels.
- Be careful with offers on social media promising quick jobs abroad.
- Keep copies of all receipts and agreements.

Merchant Navy Career Options Ashore
After years at sea, many seafarers move to shore jobs. Experienced officers and engineers work as marine superintendents, port captains, surveyors, maritime trainers, ship managers, insurance professionals and consultants. Some join government bodies or port trusts. This means a merchant navy career offers long-term options even when you want to stay closer to home.
Kerala and Maritime Opportunities
Kochi is a major maritime hub with Cochin Shipyard, the Cochin Port, the Vallarpadam International Container Transhipment Terminal and the Indian Maritime University campus. Vizhinjam International Seaport near Thiruvananthapuram has added new maritime opportunities. Many shipping companies and crewing agencies have offices in Kochi. These create jobs in port operations, ship repair, logistics and training, alongside sea-going careers.
Is a Merchant Navy Career Right for You?
Ask yourself whether you are comfortable spending months away from family, working in a disciplined environment and handling emergencies. If you enjoy travel, technology and responsibility, the career can be very satisfying. Students who prefer regular office hours and staying at home may choose shore-based maritime jobs instead.
Parents should research courses, institutes and placement records carefully before investing. Talk to alumni and check whether the institute has tie-ups with reputed shipping companies for cadet placement.
Steps to Start Your Merchant Navy Career
- Choose your department: deck, engine or electrical.
- Check eligibility, including subject marks, age and medical standards.
- Prepare for IMU CET or the relevant institute admission test.
- Select a DG Shipping-approved institute with good placement records.
- Complete pre-sea training and obtain INDoS, CDC and STCW certificates.
- Join a ship as a deck cadet or trainee engineer through a licensed company.
- Complete sea time and pass competency exams for promotion.
GP Rating: Entry After Class 10 or 12
The General Purpose Rating course is a popular entry route for students who want to start working at sea early. After the pre-sea course, ratings join ships as trainee seamen or engine ratings, helping officers and engineers with watchkeeping, maintenance and cargo work. With sea experience and further exams, ratings can progress to Able Seaman, Bosun or Fitter. Some highly motivated ratings later qualify for officer exams after meeting the required conditions.
The GP Rating route has lower course fees and shorter training than degree programmes, making it accessible for many families. However, placement depends on the institute’s tie-ups, so choose carefully.
Skills That Help You Succeed at Sea
- Strong basics in physics and mathematics for navigation and machinery.
- Good English communication for working with multinational crews.
- Physical fitness and the ability to handle heat, cold and motion.
- Discipline, punctuality and respect for safety procedures.
- Teamwork and leadership as you grow into senior ranks.
- Calmness and quick decision-making in emergencies.
Improving your English speaking helps in interviews and on board. See our guide to English speaking for job interviews.
Challenges and How to Prepare
Getting the first ship can take time, especially for candidates from institutes without strong placement support. Shipping markets also go through cycles, which affect hiring. Keep your documents valid, stay physically fit and maintain contact with licensed crewing agencies while waiting. Some candidates take shore jobs in logistics or ports during the wait to gain experience and income.
Mental health is important at sea. Long contracts, isolation and work pressure can be stressful. Good companies provide welfare facilities, internet access and support. Build healthy habits like exercise, reading and staying connected with family to cope well during voyages.
Women in the Merchant Navy
The number of women seafarers from India is growing, supported by industry initiatives and company policies. Women serve as deck officers, engineers and even Captains on international ships. Eligibility, training and career paths are the same, and several companies actively encourage female cadets. Families should not hesitate to support daughters interested in this field.
Cost of Training and Education Loans
Maritime courses can be expensive, especially degree programmes at private institutes, because they include specialised equipment, simulators and residential training. GP Rating and diploma courses cost less. Before joining, ask for a full fee breakup, including tuition, hostel, uniforms, STCW courses and medical tests. Many banks offer education loans for approved maritime courses, and some shipping companies sponsor cadets in return for a service commitment.
Sponsorship is valuable because it usually guarantees onboard training with the sponsoring company. Ask institutes which companies sponsor their students and how many seats are sponsored each year. Avoid paying extra money to anyone promising sponsorship outside official channels.
Onboard Training Tips for Cadets
Your first contract as a deck cadet or trainee engineer shapes your career. Be punctual for watches, follow safety rules strictly and ask questions when unsure. Complete your training record book regularly with officer signatures. Learn from every task, from chipping and painting to navigation and cargo work, because practical knowledge helps you in competency exams and as an officer. A good report from your first ship improves your chances with future employers.
Respect the multicultural crew and adapt to life on board. Maintain your health with regular exercise and proper sleep. Save a part of your stipend and plan your next steps, including study time for exams during leave.
Competency Exams and Promotion
Promotion in the merchant navy depends on sea time and passing competency exams under DG Shipping. Each level requires attending approved preparatory courses, written examinations and oral examinations by experienced surveyors. Officers who prepare well and gain good experience can rise to senior ranks within a decade. Continuous learning, including specialised courses for tankers, gas carriers or dynamic positioning, opens better-paying assignments.
Types of Ships and Career Choices
The type of ship you work on affects salary, contract length and lifestyle. Container ships follow fixed routes with frequent port calls and busy schedules. Oil, chemical and gas tankers pay well but require specialised training and strict safety standards. Bulk carriers carry coal, ore and grain on long voyages. Offshore vessels support oil and gas platforms and often have shorter rotations. Cruise ships offer a very different environment with thousands of passengers. Many officers gain experience on one type and then specialise.
