Marine Engineering

Marine Engineering or Bachelor of Technology in Marine Engineering is an Under-Graduate Marine Engineering course. Marine engineering is a branch of engineering that deals with nautical architecture and science. The term ‘Marine Engineering’ is meant for research conducted in oceans and coastal or inland waters connected to the sea. Marine Engineering courses deal with the construction and maintenance of ships and other sailing vessels as well.

The engineering discipline is concerned with the machinery and systems of ships and other marine vehicles and structures. During the course, marine engineers deal with a wide range of systems, including diesel engines, gas turbines, boilers, steam turbines, heat exchangers, pumps and compressors; electrical machinery; hydraulic machinery; refrigeration machinery; steam, water, fuel oil, lubricating oil, compressed gas, and electrical systems; equipment for automation and control; equipment for firefighting and other forms of damage control; and systems for cargo handling. The duration of the Marine Engineering course is four years. The Marine Engineering course is very important and in today’s time, its value has increased many times due to coastal security reasons.
