Marine engineering is the operation and support of the systems and equipment that propel and control marine vessels and of the systems which make a vehicle or structure habitable for crew, passengers and cargo.[1] This work is carried out by marine engineering officers who usually train via cadet ships sponsored by a variety of maritime organizations. There are also training centers at post-secondary institutions that offer marine engineering programs, such as Autonomous Underwater Vehicle research; marine renewable energy research; and careers related to the offshore oil and gas extraction and cable laying industries.

Marine engineering officers are responsible for propulsion and other systems such as: electrical power generation plant; lighting; fuel oil; lubrication; water distillation and separation; air conditioning; refrigeration; and water systems on board the vessel. They require knowledge and hands-on experience with electrical, electronic, pneumatic, hydraulic, chemistry, control engineering, naval architecture or ship design, process engineering, steam generation, gas turbines and even nuclear technology on certain military vessels.

History

One of the most notable figures in marine engineering in antiquity was Archimedes, who experimented with buoyancy, developed the water screw, and pre-industrial naval weapon systems. Pioneers in marine engineering in Britain include William Froude and Isambard Kingdom Brunel, who illustrated the effectiveness of the screw propeller, amongst other notable achievements. The oldest surviving marine engine was designed by William Symington in 1788. The ship 'Turbinia' first demonstrated the superiority of the steam-turbine engine, which is still used for marine propulsion today in some niche applications. In America, the University of Michigan's Department of Naval Architecture and Marine Engineering can be tracked to an 1879 act of Congress, which authorized the U.S. Navy to assign a few officers to engineering training establishments around the country. Mortimer E. Cooley was the first lecturer in the department.[2]
