2. State concept & function of Auxiliary equipment of Main propulsion plant?

a.   Generator

-Supply electric energy for the ship to serve many different objects. Remember that, there must be at least two generators in MPP

-Generators can be driven by diesel engines , steam engine, steam turbine or some time by Main Engine (Shaft Generator)

b.  Compressed air system

-Generates and stores compressed air with high pressure for starting and reversing the main engines, starting generator engines, cleaning parts of the engine

-Compressed air is also used in remote control and automatic control systems. Compressed air system consists of compressors, reservoirs (air tank), non-reversible valves, relief valves, and compressed air pipes...

c.  Auxiliary boiler

-Supplyes steam to heat fuel, water, diesel engine (before starting) and cabins. In addition, it also serves steam machineries and equipment (such as cargo pumps on tanker ships).
