Engine Room Department The Engine Room department is responsible for Overall Maintenance of Ship’s Machinery.

Chief Engineer-Responsibility Chief Engineer is responsible for all operations and maintenance covered by engineering equipment throughout the entire ship. Chief also determines the fuel, lube oil, and other consumables required for a voyage, required inventory for spare parts, oversees fuel, lube, and slop oil transfers, prepares the engine room for inspection by local marine/safety authorities, oversees all major maintenance, is required to be in the engine room during maneuvering operations, and is in charge of the engine room during emergency situations.

Second Engineer-Responsibility Supervises the daily operation of the engine room and engine department and reports directly to the Chief. Typically the busiest engineer aboard the ship Usually in charge of preparing the engine room for arrival, departure, or standby and oversees major overhauls on critical equipment.

Engine Room An engine room is where the main engine(s), generators, compressors, pumps, fuel/lubrication oil purifiers and other major machinery are located. Engine Rooms are typically towards the stern, or rear, of the boat from the crews living accommodations. On modern ships, a sound-proofed, air-conditioned engine control room (ECR) is situated next to the engine room (ER), for the ship's machinery control systems.

Main Engine Main Engine is connected to the Propeller and propels the ship. Main Engines run using Heavy Oil or Diesel Oil.

Main Engine

Auxilliary Engine Auxilliary Engines are required for Ship’s Power requirement. When Main Engines do not run (from anchorage to harbor, canal ways), auxilliary engines will operate. There would be 3,4,6,8 Auxilliary engines in a ship depending on the size of the ship Auxilliary Engines are also used in driving ballast-trim pumps, water circulating pumps, boiler feed pumps, fuel oil pumps etc.

Auxilliary Engine

Engine Cooling The engine(s) get their required cooling by means of liquid-to-liquid heat exchangers connected to fresh seawater or divertible to recirculate to tanks in the engine room which are also full of sea water. The heat exchangers are plumbed in so that oil is represented by a yellow mark on the flange of the pipes, and relies on paper type gaskets to seal the mating faces of the pipes. Sea water or brine, is represented by a green mark on the flanges and internal coolant is represented by blue marks on the flanges.

Fire Precautions Engine rooms are hot, noisy, sometimes dirty, and potentially dangerous. The presence of fuel, high voltage equipment, engines etc., means that a serious fire hazard exists in the engine room, which is monitored continuously. Engine rooms employ some means of providing air for the operation of the engines and associated ventilation

Engine Control Room

Propeller Basically a type of fan which transmits power by converting rotational motion into thrust for propulsion of ship through water. It is effected by rotating two or more twisted blades about a central shaft, in a manner analogous to rotating a screw. The blades of a propeller act as rotating wings and produce force through application Newton’s third law.

Rudder and Propeller

Rudder A rudder is a device used to steer a ship. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. In larger vessels, cables, pushrods and hydraulics may be used to link rudders to steering wheels. In typical aircraft, pedals operate rudders via mechanical linkages.

Drydock A drydock is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Drydocks are used for the construction, maintenance, and repair of ships, boats, and other watercraft.
