Auxiliary Marine Machinery
Marine machinery is designed to ensure the proper functioning of a ship’s main engines, piping systems, and equipment. Auxiliary marine machinery includes pumps, compressors, and blowers for circulating fuel and the fresh water and seawater used in cooling systems, for supplying air to the starting system of the main engine, for cooling refrigerated holds, and for air-conditioning various parts of the ship and for refrigeration machinery.
Auxiliary marine machinery also includes separators for removing water and other contaminants from fuel and oil, steering machinery, capstans, windlasses, winches for anchoring, mooring, and cargo loading, and cranes.
Other items include heat exchangers used to condense vapors and to heat and cool working fluids, such as water, oil, and air, filters for the seawater and fuel supplies, and separators for bilge water.
