Engineman	EN
	Enginemen are responsible for internal diesel and gasoline engines. They also maintain refrigeration, air-conditioning, distilling plant engines and compressors.

Engineman (ENs) Engineman operate and maintain diesel engines and reduction gears used for ship propulsion and auxiliary machinery such as diesel generators, pumps and oil purifiers. They also maintain auxiliary machinery outside of main machinery spaces, such as electro hydraulic steering engines and elevators, refrigeration plants, air conditioning systems and desalinization plants. They will also operate and maintain compressed gas producing plants, deck equipment including cranes, winches and hoists, condensers and heat exchange devices and small boats.

 The duties performed by ENs include:

 • aligning piping systems for oil, water, and air for controlling the operation of diesel engines used for ship propulsion and service systems;

• controlling operation of diesel generators used to produce electrical power;

• cleaning, adjusting, testing and performing other preventive maintenance on a ship's auxiliary boilers, main engines, diesel generators and other auxiliary machinery including steering engines, elevators, winches, pumps and associated valves;

• operating and maintaining desalinization plants (distilling plants) to make fresh water from sea water;

• maintaining refrigeration plants, air conditioning systems and galley equipment;

• repairing or replacing valves, pumps, heat exchangers, compressors, steam turbines and hydraulic or pneumatic control devices;

• operating and maintaining small boats.

• making entries in and analyzing machinery operating records and reports.

Working Environment

Engineman work any where on a ship in main engine rooms, auxiliary machinery rooms, engine rooms or shops. These locations are sometimes hot and noisy. ENs may be required
to perform some heavy physical work. They must be able to work closely with others and, in some cases, with limited supervision.

Credit Recommendations

The American Council on Education recommends that semester hour credits be awarded in the vocational certificate or a lower-division bachelor's/associate's degree categories for courses taken in this rating on machine technology, machine shop mathematics, blueprint reading and metric system of measurement.

Qualifications and Interests

Engineman should have clear speech, physical stamina, manual dexterity and the ability to work with others as a team. They should know how to use common hand and power tools and enjoy working with mechanical devices.
Other helpful characteristics are resourcefulness and an interest in learning new ideas and skills. Curiosity, record keeping talent and physical strength are also required. Normal hearing is required.

Opportunities

The Navy has a continuing need for qualified Engineman. Approximately 5,500 men and women perform duties in the EN rating aboard ships and at shore stations. Opportunities for placement are excellent for qualified candidates.

EN - Diesel Engine/Auxiliary Systems Maintainer

Diesel Engine - Auxiliary Systems Maintainers operate, service, and repair internal combustion engines used to power some of the NAVY's ships and most of the small craft. They also operate and maintain electro-hydraulic systems, steering engines, refrigeration and air conditioning systems, air compressors, desalinization plants and small boilers. These maintainers work under the supervision of a mentor.

EN - Diesel Engine/Auxiliary Systems Manager

Diesel Engine - Auxiliary Systems Managers operate, service, and repair internal combustion engines used to power some of the NAVY's ships and most of the small craft. They also operate and maintain electro-hydraulic systems, steering engines, refrigeration and air conditioning systems, air compressors, desalinization plants and small boilers. These managers have mastered a trade or skill and are qualified to mentor Diesel Engine / Auxiliary Systems Technician(s) and Diesel Engine / Auxiliary Systems Maintainer(s) and carry on the craft independently.

EN - Diesel Engine/Auxiliary Systems Technician

Diesel Engine - Auxiliary Systems Technicians operate, service, and repair internal combustion engines used to power some of the NAVY's ships and most of the small craft. They also operate and maintain electro-hydraulic systems, steering engines, refrigeration and air conditioning systems, air compressors, desalinization plants and small boilers. These technicians are expected to perform work independently and mentor Diesel Engine / Auxiliary Systems Maintainer(s) with very limited supervision.
