Ships are responsible for transportation of people and goods from one part of the world to another. To be precise, around 96% of goods transportation takes place through ships! In short, shipping sector touches our daily lives directly or indirectly. I mentioned the above facts just to underline and emphasize the size of this industry and the scope associated with it. Marine Engineering is a discipline of engineering that is directly related to shipping industry.


Marine Engineering: Introduction

A ship functions due to its various parts, which work in tandem. Some of the well known machines and parts present in a ship are- Generators, Engines, Fuel Tanks, Refrigeration Units, Boilers, Pumps, Turbines, Electrical and Electronic Systems etc.


A marine engineer is responsible for designing, planning, manufacturing, maintaining and repairing various machinery and parts of a ship, like the ones I’ve mentioned above. A ship can be compared to human body. For its efficient functioning, various parts (organs) have to function smoothly. A marine engineer is trained to develop, maintain and repair such parts of a ship!


Marine engineer can function in two different ways- Ashore work and aboard work. After completing Diploma in Marine Engineering, one may take up ashore work and take up tasks such as designing, manufacturing, maintaining and repairing parts of ships.


After completing Diploma in Marine Engineering, one may go for 2 years long pre sea training, complete it, and become a marine engineer aboard a merchant navy ship!


Merchant navy (on board) job is much more rewarding than the ashore work. It involves higher salary, lots of travel, perks (free boarding and food), longer vacations etc.


Let us check out eligibility criteria now.


Eligibility criteria

Most Institutes offering Diploma in Marine Engineering course have 10+2 Science stream (with Physics, Chemistry and Mathematics subjects) as the minimum educational qualification required. Minimum aggregate marks required is 50% (it may vary from one institute to another).


10th standard students, who want to pursue Diploma in Marine Engineering, should select Science stream (Mathematics group) after 10th standard.


Candidate must also be physically and mentally fit. Due importance is given to medical and physical fitness of a candidate.


Admission process

Most institutes follow merit based admission process. Marks scored in entrance test (state/national level) and 12th board examination are taken into consideration. Seats are allotted to eligible candidates based on merit marks.


Some of the reputed institutes have their own qualifying test and interview. Candidates who are interested in such institutes must pass the qualifying test and the interview that follows the test.



To get a better idea about the course structure, let us run through some of the important subjects present in Diploma in Marine Engineering program. Note: Only important subjects have been mentioned.

  • Ship Design and Construction
  • Engineering Mechanics
  • Diesel Engine
  • Boilers
  • Refrigeration and Air Conditioning System
  • Fuels, Oils and Lubricants
  • Safety Technology and Management
  • Electrical and Electronic System
  • Thermodynamics
  • Hydraulics
  • Welding Technology
  • Communication Skills
  • Engineering Graphics
  • Turbines


Along with theoretical classroom sessions, many of the subjects mentioned above also have practical sessions associated with them. The 3 years long academic program is divided into 6 semesters, with each semester lasting for a period of 6 months. Evaluation is done at the end of each semester via written as well as practical examinations.


Further studies and courses

If you are interested in a merchant navy career (on board), you may go for 2 years long pre sea DME course. This course will enable one to join a merchant navy ship as a junior engineer. After 6 months of on board training, one may appear for MEO Class 4 examination. On clearing this examination, one will be given the rank of fourth engineer aboard the ship! With further examinations and sea service, one may rise through the ranks and become a Chief Engineer some day!


Other than the above mentioned pre sea training course, one may secure admission directly into the second year of B.E./B.Tech. Marine Engineering, after completing Diploma in Marine Engineering program!


After gaining Bachelor’s Degree, one may follow it up with advanced relevant courses like M.E./M.Tech., M.Sc., PG Diploma programs etc.


Career prospects and job opportunities

Previously, I mentioned how enormous and important the shipping industry is. World economy, to an extent, is dependent on this industry. Diverse job opportunities are available in front of marine engineers. Government and private sector jobs related to shipping industry are the prime attractions.


Talking about job opportunities ashore, one may find work in ports operated by the Government or private players. One may also find work at shipyards. Firms designing and building ships are well known recruiters. Companies manufacturing machinery, parts and devices used in ships are also known to recruit marine engineers. Some of the well known job profiles available include-

  • Marine Engineer
  • Maintenance Engineer
  • Quality Control Engineer
  • Marketing professional
  • Machine/Parts Design Specialist
  • Port Manager/Engineer
  • Technical Supervisor
  • Technical Consultant


Coming to on board jobs, merchant navy offers rewarding as well as challenging opportunities to qualified marine engineers. After completing pre sea training, sea service and examination, one may start working aboard a merchant navy ship as a marine engineer.


The tasks of a marine engineer aboard a merchant navy ship include- following instructions from Captain and superior engineers, supervising engine room crew, operation & maintenance of machinery on ship, ensure overall safety etc.


The ranks available are (one may rise through the ranks with experience and by appearing for examinations)-

  • Chief Engineer
  • Second Engineer
  • Third Engineer
  • Fourth Engineer
  • Engine Cadet/Junior Engineer
