Marine engineering

Overview
In maritime transportation, the engine department or engineering department is an organizational unit aboard a ship that is responsible for the operating the propulsion systems and the support systems for crew, passengers and cargo. This work is carried out by marine engineering officers who usually train via cadet ships sponsored by a variety of maritime organizations. Other shipboard departments typically include the deck department

Marine engineer officers emerged with the arrival of marine engines for propulsion, largely during the latter half of the 19th century. Early marine engineers were known as "stokers" as they 'stoked' the coal fires of steam engined ships more or less from the middle of the 19th to the middle of the 20th centuries; the term is still used affectionately by modern ship's engineering staff to describe their role.

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.
