Face to face with engine room

What, that is heart for humans is the engine room for the ship. It is what which is most important something which keeps it alive to sail across. Its loud and hot and you have to watch your steps on stairs to avoid any trouble.

What the book says is: On a ship, the engine room, or ER, is the propulsion machinery spaces of the vessel. To increase a vessel's safety and chances of surviving damage, the machinery necessary for operations may be segregated into various spaces. The engine room is generally the largest physical compartment of the machinery space. It houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine, or some combination of these (such as CODAG; see Category: Marine Propulsion). On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered.

On a large percentage of vessels, ships and boats, the engine room is located near the bottom, and at the rear, or aft, end of the vessel, and usually comprises few compartments. This design maximizes the cargo carrying capacity of the vessel and situates the prime mover close to the propeller, minimizing equipment cost and problems posed from long shaft lines. The engine room on some ships may be situated mid-ship, especially on vessels built from 1900 to the 1960s. With the increased use of diesel electric propulsion packages, the engine room(s) may be located well forward, low or high on the vessel, depending on the vessel use.

What is it all about( Easy explanation/ UN-bookish): It is the machinery compartment situated at the aft of the ship below waterline. It consists of 3 decks having different machineries mounted on it. The lowest most floor or platform is called the third deck below which are the bilges a place where all the drains from the engine room other than of oil containing sources. 
                           Third deck is commonly called as machinery deck in the ship. It has main engine, Auxiliary engines, Auxiliary boilers, Hot well, Fresh water generator, Bilge and blast Pump,Main engine sea water Pump, Ejector pump, Main engine jacket water pump, Main engine lube oil cooler, Main engine jacket water cooler, Main engine lube oil storage tank, Main engine lube oil clarifier and purifier, Reciprocating bilge pump, Oily water separator, Main air bottle,Main air compressor, Hand air compressor, Emergency air bottle, Fuel oil transfer pump, General service pump, Fire pump, Fuel oil bunkering valve chest and bilge and blast valve chest.

Second deck is commonly known as the utility deck in the ship and compromises of control room, Electrical stores, Spare gear stores, Injector testing bay, Various display table, Emergency fire pump, Emergency air compressor, Workshop, Incinerator, Fuel oil mixing column, Air conditioning and refrigeration plant, Filters, Changing room for crews, Fresh water hydrophore, Boiler reciprocating pump, Feed water tank, Fresh water tank, Fuel oil tank, Main engine expansion tank, Auxiliary engine expansion tank, Auxiliary engine fuel oil service tank.

So far we have discussed about bottom or third deck and middle or second deck platforms. Now we will talk a very little about the first deck, it is at the top most and mainly contains engine control room and various other compartments and machines stated in the given diagram. It is commonly known as the weather deck on the ship.
