Main engine deck of a cargo vessel Location of a ship's engine room on a bulk carrier Engine room of the Mercy Ship Caribbean Mercy in 1997. Her propulsion diesel is an MAK. EMD diesels in the engine room of the Research Vessel Davidson circa 2002. On a ship, the engine room (ER) [1] is the compartment where the machinery for marine propulsion ...
The first German jet engines built during the Second World War used a mechanical APU starting system designed by the German engineer Norbert Riedel.It consisted of a 10 horsepower (7.5 kW) two-stroke flat engine, which for the Junkers Jumo 004 design was hidden in the intake diverter, essentially functioning as a pioneering example of an auxiliary power unit for starting a jet engine.
Located underneath the front hood is the traction assembly – a K 6 S 310 DR diesel engine and a TD 802 traction generator – and auxiliary machinery powered by the diesel engine via a hydrodynamic transmission. Chillers and ventilators are located here as well. TE 006 traction motors are axle-mounted on the wheel sets.
The 131-9D initially was designed for the McDonnell Douglas MD-90 series; the 131-9B became standard equipment on Boeing 737NG; the 131-9A on the Airbus A320 family. [4] The 131-9C has entered service aboard the Airbus A220 (formerly Bombardier C-Series). The 131 Series uses a two-stage axial turbine and a single generator which starts the APU. [5]
A steam generator on a ship is an auxiliary boiler which draws high-pressure superheated steam from the vessel's propulsion system [1] to generate low pressure saturated steam. This secondary steam is then used to power auxiliary shipboard engines driving winches or pumps, or to meet any steam requirement that does not require superheating ...
The engine room on a bulk carrier is usually near the stern, under the superstructure. Larger bulk carriers, from Handymax up, usually have a single two-stroke low-speed crosshead diesel engine directly coupled to a fixed-pitch propeller. Electricity is produced by auxiliary generators and/or an alternator coupled to the
A unique design under project SCB 245, [4] Narwhal was her own class. Forward of the reactor compartment she was broadly similar to the contemporary Sturgeon-class submarines, but with a slightly larger diameter and the relocation of the auxiliary diesel generator from the bow compartment to the auxiliary machine room in the operations compartment.
They make replacement parts for a ship's engine auxiliary equipment, such as evaporators, air compressors and pumps. The repair of deck equipment, including winches and hoists, condensers and heat exchange devices are completed by machinist mates. Machinery repairmen assist enginemen by repairing or producing parts in the machine shop ...
