Marine Engineering is a popular sub-discipline of Engineering and Technology. It has a good scope for learning and employability. This branch of Engineering and Technology is concerned with watercraft manufacturing and development, thus, it deals with the science of nautical architecture. The term 'Marine Engineering' defines the research that is conducted in oceans and coastal or inland waters, connected to the sea. The construction and operation of mechanical equipment like docks and harbour installations are fulfilled by Marine Engineering. Marine Engineers are not only specialized in the field of manufacturing, but they are also responsible for the management of the watercraft. This means that they are able to detect technical failures of all-purpose boats, ships, bow riders, cabin cruisers, cuddy cabins, dinghies and provide a solution to fix such technical issues.

Marine Engineering is closely related to other disciplines like nautical sciences, oceanography, automotive and mechanical engineering, and naval architecture. Marine Engineering students need to possess good knowledge on topics like physics, mathematics, propulsion, mechanics, and computer-aided design.

Marine Engineers work to design and build watercraft propulsion. They are the masterminds behind watercraft machinery, both big and small. The accountability of a Marine Engineer's work extends to that of onboard systems and off board systems pertaining to the maritime. These would include steering or control systems, propulsion systems like gas turbines, diesel engines, or nuclear reactors. The main focus of Marine Engineering is to explore in and around the water as it supports key activities like naval defence, environmental research, international trade, and resource extraction.
