Engine Room
The engine room on a ship is usually the largest space on the vessel and typically consists of three platforms: the top, middle, and bottom. The vessel’s primary propulsion system i.e. the engine, is housed there. Engine rooms are vast and can often span several decks.
The upper platform includes spare components for the main engine, pumps, auxiliary machinery, vessel operation, and numerous tanks and other equipment.
Pumps like the primary engine booster pump and the fresh water condenser pump are located on the middle platform. Auxiliary machinery such as air compressors, dehumidifiers, and purifiers may also be located on this platform. On the bottom platform, on most ships, you will find the primary seawater, sludge, refrigerator, and other pumps.
