Marine engineering is the field of engineering that designs, builds and maintains the machinery and systems that keep ships, boats, submarines and offshore rigs running. It sits at the heart of the merchant navy and shipbuilding industry, and in India the profession is trained and certified under standards set by the Directorate General of Shipping and the International Maritime Organization. This guide covers what marine engineering is, courses and eligibility, top colleges, syllabus, fees, salaries and careers.
What Is Marine Engineering?
Marine engineering is the branch of engineering that deals with the design, construction, operation and maintenance of the machinery and internal systems of ships, boats, submarines, oil rigs and other seagoing craft. Marine engineers keep a vessel's engines, propulsion, electrical and mechanical systems running safely and efficiently at sea.
- It covers the construction, operation, installation, repair and maintenance of a ship's machinery.
- Marine engineers form and run the ship's internal engineering systems.
- The discipline blends mechanical, electrical and naval engineering with seamanship.
- It is a professional course leading to certification for work at sea or ashore.
What Do Marine Engineers Do?
Marine engineers build, install and maintain a ship's engines, boilers, pumps, generators and steering gear, working alongside naval architects, technicians and deck officers. On board they operate the engine room, monitor fuel and machinery, and carry out repairs. A bachelor's degree in marine engineering and certification are usually required to work as a marine engineer.
Marine engineers work both at sea, running and maintaining the engine room of a vessel, and ashore in shipyards, design offices, ports and regulatory bodies. Their responsibilities span propulsion systems, auxiliary machinery, electrical installations and safety equipment, all of which must meet international standards.

Salaries vary widely by country, rank and sea time. In the United States the median annual wage for marine engineers and naval architects was 105,670 dollars in May 2024, according to the US Bureau of Labor Statistics. In India, shipboard pay rises steeply with rank, from a junior fifth engineer to a chief engineer.
In India, monthly earnings on merchant navy vessels depend heavily on rank and the shipping company. The reported industry ranges below rise sharply as an engineer gains sea time and clears Certificate of Competency examinations. Salaries abroad and on foreign-flag ships are typically higher and often quoted in US dollars.
| Rank (Merchant Navy) | Approx. Monthly Salary in India 2026 |
|---|---|
| Fifth / Junior Engineer | Rs 35,000 - 75,000 |
| Fourth Engineer | Rs 1.5 - 2.25 lakh |
| Third Engineer | Rs 2.5 - 3 lakh |
| Second Engineer | Rs 4 - 5 lakh |
| Chief Engineer | Rs 5 lakh and above |
Which Are the Best Marine Engineering Colleges in India?
India's best-known marine engineering institution is Indian Maritime University, Kolkata campus, formerly the Marine Engineering and Research Institute, whose roots go back to the Directorate of Marine Engineering Training set up in 1949. Other respected options include IMU's other campuses, Tolani Maritime Institute, AMET University and several Directorate General of Shipping-approved private colleges.
- Indian Maritime University (IMU), Kolkata campus - formerly MERI, roots in DMET set up in 1949
- Indian Maritime University - other campuses at Mumbai Port, Chennai and Visakhapatnam
- Tolani Maritime Institute, Pune
- Academy of Maritime Education and Training (AMET), Chennai
- Cochin University of Science and Technology (CUSAT), Kerala
- Andhra University College of Engineering, Visakhapatnam
- Coimbatore Marine College, Tamil Nadu
What Are the Marine Engineering Courses and Eligibility?
Marine engineering is offered as a four-year B.Tech, a B.E., a B.Sc. in nautical science and postgraduate M.Tech degrees, plus diploma and graduate marine engineer courses. For the B.Tech at IMU, candidates need at least 60 percent aggregate in Physics, Chemistry and Mathematics in 10+2, 50 percent in English, and a valid IMU CET rank.
- B.Tech in Marine Engineering (four-year bachelor degree)
- B.E. in Marine Engineering (bachelor degree)
- B.Sc. in Nautical Science (bachelor degree)
- M.Tech in Marine Engineering (postgraduate)
- Diploma and Graduate Marine Engineer (GME) courses
Admission to the B.Tech at Indian Maritime University is through IMU CET, a national online entrance test held in May each year. Beyond the 60 percent PCM requirement, candidates must be medically fit under the Merchant Shipping (Medical Examination) Rules and meet the age limits set for each category.
What Is the Marine Engineering Syllabus?
The marine engineering syllabus blends mechanical, electrical and naval subjects. Core topics include basic thermodynamics, electrical and electronics engineering, ship structure and construction, marine machinery and system design, marine steam and internal combustion engineering, ship operation and management, and fire control and life-saving appliances. Practical workshop training and simulator sessions run alongside theory throughout the course.
- Basic thermodynamics
- Basic electrical and electronics engineering
- Ship structure and construction
- Marine machinery and system design
- Marine steam and internal combustion engineering
- Ship operation and management
- Fire control and life-saving appliances
What Are the Fees for Marine Engineering?
Fees depend on the campus and whether the college is government-funded or private. At Indian Maritime University the four-year B.Tech in Marine Engineering costs roughly 2.5 to 2.75 lakh rupees per year, while B.Sc. Nautical Science is similar. Private Directorate General of Shipping-approved colleges can charge more, so confirm current fees directly with each institute.
- IMU B.Tech Marine Engineering: roughly Rs 2.5 to 2.75 lakh per year (about Rs 10 to 11 lakh for the four-year course).
- B.Sc. Nautical Science: broadly similar per-year fees.
- Private DG Shipping-approved colleges: often higher, so verify fees directly with the institute.
- IMU CET 2026 application fee: Rs 1,200 for General, OBC-NCL and EWS, and Rs 800 for SC and ST.
What Career and Job Options Does Marine Engineering Offer?
Marine engineering graduates can sail as ship's engineers in the merchant navy or move into shore roles such as marine surveyor, field engineer, engineering technician, ship designer, port and dockyard engineer, or classification-society inspector. Employers include shipping lines, shipyards, oil and gas firms, the navy and regulatory bodies, offering strong global demand and steady career progression.
