Ship engineers are chargeable for propulsion and different ship structures together with: electrical energy era plant; lighting; fuel oil; lubrication; water distillation and separation; air conditioning; refrigeration; and water structures on board the vessel. They require knowledge and fingers-on experience with electric powered energy, electronics, pneumatics, hydraulics, chemistry, steam technology, gasoline generators and even nuclear era on positive navy and civilian vessels.
Engineering Positions in Merchant Navy (Ships)
Ship Engineering Officers Ranks (typical for a British Merchant Vessel – US equivalents in italics):Marine Engineering Officers
Chief Engineer
In charge of the engine department. Reports only to the Master. The Chief Engineer's training, responsibility and rank are all superior to those required for a Chief Officer.
Second Engineer
1st Assistant Engineer: In charge of the day-to-day running of the engine department. Often in charge of main engine maintenance. Takes the 4–8 watch. He is the equivalent of the Chief Mate.
Third Engineer
2nd Assistant Engineer: Usually in charge auxiliary engines & boilers. Takes the 12–4 watch.
Fourth Engineer
3rd Assistant Engineer: Usually in charge of air compressors, purifiers, pumps and other auxiliary machinery. Takes the 8–12 watch. Sometimes in charge of boilers.
Electrical Officers
(Not always part of manning requirements, but generally present on more sophisticated vessels)
Electro-technical Officer (ETO)
Officer who is responsible for the maintenance of electronic equipment including automation systems and instrumentation process and control equipment, and/or general electrical equipment. Reports to Chief Engineer.
Electrical Officer
Officer who is responsible for the maintenance of general electrical equipment such as motors, transformers, lights, reefer outlets etc. Reports to ETO / Chief Engineer.
Other Engineering Officers
Junior Engineer
No official responsibilities - this rank is reserved for those who are qualified as Fourth Engineers but lack the experience necessary to take a watch.
Cadet
A trainee officer. Understudies the other engine department personnel.
ETO Cadet
A Trainee Electro-Technical officer. Understudies the other engine department personnel specific to ETO position.
The USA Army ships have a various number of engineering officials, relying upon the dimensions of the crew, occupying positions named for subsidiary obligations of the engineering officer. the two maximum ranking subordinates are normally the principle propulsion assistant (mpa), answerable for operation and renovation of propulsion equipment, and the harm manipulate assistant (dca), responsible for prevention and control of damage. anticipation of warfare damage will increase the significance of responsibilities of the latter position on warships. a dca regularly stands routine deck or engineering watches, but spends his off-watch time overseeing maintenance of watertight integrity and firefighting device. a dca's struggle station usually consists of responsibility for controlling the deliver's stability, listing and trim with the aid of flooding and dewatering undamaged compartments as vital to save you capsizing. additional engineering officials may consist of an electrical officer, answerable for the deliver's electrical producing and distribution device as defined above, and an auxiliaries (or a division) officer, accountable for pumps, air flow blowers, refrigeration compressors, and windlass equipment as defined above for the fourth engineer.
Typically, a deliver's engine department is administered by using the engineering officials but manned with other occupational specialties of the seafarer's alternate like:
- Machinist/more healthy: a score (or petty officer) who is specialized in fabrication, welding, and many others.
- Motorman: a, no longer always, qualified engine rating who stands an eye with the engineer officer, as well as appearing menial tasks and helping engineering officers at some point of preservation.
- Oiler: a rating who's responsible for ensuring that machinery is satisfactorily lubricated. Plays menial responsibilities inclusive of cleansing, sounding tanks and so on.
- Wiper: the lowest score in the engine room and is tasked with keeping the equipment spaces clean and tidy. Wipers normally pass on to end up oilers as soon as they're acquainted with engine room equipment and unique routines.
- Stoker: now defunct, the stoker become an engine department score with obligation for shoveling coal into the boiler furnaces.
- Coal trimmer: now defunct, the coal trimmer changed into an engine department rating with duty to load coal in the bunkers and to move the coal from the bunkers to the stokers
The oldest surviving marine engine became designed via william symington in 1788. The deliver 'turbinia' first tested the superiority of the steam-turbine engine, which remains used for marine propulsion these days in a few niche applications. In the united states, the university of michigan's department of naval structure and marine engineering can be tracked to an 1879 act of congress, which legal the USA Navy to assign a few officials to engineering training institutions around the USA .. Mortimer e. Cooley changed into the primary lecturer inside the department.
