Enginemen (ENs) operate, service and repair internal combustion engines used to power some of the Navy's ships and most of the Navy's small craft. Most enginemen work with diesel engines. Enginemen also operate and maintain electrohydraulic controllable pitch propeller systems and steering engines, refrigeration and air conditioning systems, air compressors, desalinization plants and small auxiliary boilers.

Enginemen perform their duties in surface ships.

The duties performed by ENs include:

  • aligning fuel, water and air piping systems and controlling operation of diesel engines used for ship and small craft propulsion, and to generate electrical power;​
  • cleaning, lubricating, adjusting, testing and performing other preventive maintenance on diesel engines, reduction gears, air compressors, hydraulic or pneumatic clutches, steering engines and controllable pitch propeller systems;
  • operating and maintaining desalinization plants used to make fresh water from sea water;
  • operating and servicing refrigeration plants and air conditioning systems;
  • repairing or replacing valves, pumps, compressors, heat exchangers and control devices used with diesel engines and gas turbines; making entries into and analyze machinery operating records and reports.

Working Environment

Enginemen work in engine rooms or shops which, at times, may be warm and noisy.

They may also work outdoors aboard small craft. The work performed is sometimes physical. Although enginemen often work closely with others, they may also be required to work alone with limited supervision.
