Merchant Navy Marine Engineer

Running and looking after the ship's main engine, generators, boilers, pumps, cooling, fuel and electrical systems. Standing watches in the engine room, doing repairs and planned maintenance, and following safety and pollution rules. At higher ranks you manage the engine crew, spares, budgets and inspections.

A day in the work
On a typical day you stand a four-hour watch in the engine room, once in the morning and once in the evening. You check temperatures, pressures and alarms, walk round the machinery and note readings in the log. Between watches you fix a pump, overhaul a purifier or help with planned maintenance with the other engineers. The engine room is hot and noisy. When the ship reaches port, you also handle fuel, spares and inspections.

1. Step 1 · Class 9–11Choose Physics, Chemistry and Maths in Class 11–12, and aim for 60% or more in PCM and 50% or more in English. Get your eyesight and colour vision checked early. Sea service needs good vision and no colour blindness, so it is better to know before you plan around it.
2. Step 2 · Class 12Appear for IMU-CET. In 2026 it was a computer-based test held on 24 May, with negative marking (reported). Registration usually opens in February–April, so check imu.edu.in each year. IMU campuses run their own online counselling. Other approved institutes admit you on your IMU-CET rank. (reported — check with the official body)
3. Step 3 · Before joiningGet a medical fitness certificate from a DG Shipping-approved doctor. Keep a valid passport ready (reported by one approved institute). Private institutes may ask for a shipping-company sponsorship. DG Shipping says sponsoring companies must give sea time after training. (reported — check with the official body)
4. Step 4 · 4 yearsB.Tech Marine Engineering at a DG Shipping-approved institute. You study thermodynamics, machinery, electrical and control systems. You also do workshop work, simulators and the STCW safety courses.
5. Step 5 · After the degreeJoin a ship as a trainee engineer and complete approved sea service. For the first certificate, DG Shipping requires at least six months of engine-room watchkeeping on a ship with 750 kW or more of main engine power. Your work is recorded in a training record book.
6. Step 6 · First certificatePass the MEO Class IV Certificate of Competency assessment, which has written and oral parts, at a Mercantile Marine Department. Then you can work as a watchkeeping engineer. This is usually the fourth engineer rank.
7. Step 7 · Years laterFor Class II (second engineer), DG Shipping requires at least 12 months of sea service after Class IV Part B, then an exam. For Class I (chief engineer on ships of 3,000 kW or more), you need more approved sea service and another exam. Certificates last five years and must be renewed with medical fitness and sea service.

• Direct B.Tech after Class 12Who: Students with PCM at 60%+ and 50% in English. IMU-CET, then a 4-year B.Tech Marine Engineering at an IMU campus or an approved private institute, then sea time and the Class IV exam.
• Graduate Marine Engineering (GME) after a mechanical degreeWho: BE/B.Tech in Mechanical Engineering or Naval Architecture with 50% in the final year (as listed in DG Shipping's GME rules). Company sponsorship is usually needed (reported). A one-year pre-sea course, then about six months on a ship. After that you can sit for the Class IV certificate. The GME maximum age is reported as 28 years.
• Lateral entry into 2nd year of the B.TechWho: Students who passed the first year of an AICTE-approved Mechanical or Electrical engineering degree (60%), or a 3-year diploma in Mechanical, Marine or Electrical engineering (55%). Qualify in IMU-CET, then join year 2 of the 4-year B.Tech. This is from DG Shipping's eligibility circular, so confirm that the current rules still allow it.

Fees from: IMU – fee structure for IMU campuses (2021 version) · HIMT College – 2026-27 fee table (private institute; reported) · IMU official fee PDF for UG programmes (CET 2017 notice), B.Tech Marine Engineering residential. Fees change every year — check the college's own fee page before you pay.

Pay is low to moderate as a trainee, rises with each certificate and rank, and varies a lot with the shipping company, ship type and flag. Chief and second engineers earn much more than junior engineers. Pay is usually for months at sea followed by leave, so it is not a regular monthly job.

Women can join this career, and the reported 2026 age limit for women in the B.Tech is 2 years more than for men in each category. SC/ST candidates get a 5% PCM relaxation and a higher age limit (reported). Government data shows women are still under 2% of Indian seafarers, and the Ministry's 'Sagar Mein Samman' initiative gives financial help to women seafarers (PIB). Sea service needs strict medical fitness, including eyesight and hearing, so students with certain disabilities may not qualify. Check the current medical rules first.

• Class 7–9With an adult, look at how a bicycle chain, a fan motor or a pressure cooker works. Draw how the parts move. Engines are just many such parts working together.
• Class 10–12Get an eye and colour-vision test done. Then look at the IMU website for the IMU-CET syllabus and mock test, and find out which Class 11–12 chapters of Physics, Chemistry and Maths matter most.Open link ↗
• College or afterDo a free NPTEL course in thermodynamics or fluid mechanics to see if the basics of engines interest you. It is useful for the B.Tech and for the Class IV exam later.Open link ↗

• Only DG Shipping-approved institutes count for sea service. Check the institute's approval on dgshipping.gov.in before paying any fee. DG Shipping also publishes on dgma.gov.in, which uses the name Directorate General of Maritime Administration.
• DG Shipping says candidates must work in tough conditions on board ships and be physically and mentally strong. Institutes must check medical fitness before admission.
• Reported 2026 eyesight standard for engine-side candidates: unaided vision of 6/12 in each eye, or 6/9 in one eye and 6/18 in the other. Colour vision must be normal. Confirm the exact current standard with a DG Shipping-approved doctor.
• India supplies about 12% of the world's seafarers, nearly 3.08 lakh people according to a DG Shipping presentation from October 2025. Jobs depend on shipping companies, so hiring can rise and fall.
