On board, the engine room or ER is the ship's propulsion engine space. To improve the safety of the vessel and the possibility of surviving damage, the machinery required for operation can be separated into various spaces. The engine room is generally the largest physical compartment of the engine room. This is the main driving house of the ship, usually some variation of a hot engine - a diesel engine, a gas or steam turbine, or some combination of these (like CODAG; see Category: Marine Drive). On some vessels, the engine room may consist of more than one engine room, such as the front and rear spaces, or the engine room of the port or the right, or may be simply numbered.
On most boats, boats and boats, the engine room is located near the bottom, and behind, or behind, the end of the ship, and usually consists of several compartments. This design maximizes the cargo carrying capacity of the vessel and puts the prime mover close to the propeller, minimizing equipment costs and problems arising from the long shaft line. The engine room on some vessels may be located in the middle of the ship, especially on ships built from the 1900s to the 1960s. With the increasing use of diesel electric propulsion packages, machine spaces can be well placed forward, low or high on boats, depending on the use of the vessel.

Machine
The engine room of the motorboat usually contains several machines for different purposes. The main engine, or propulsion is used to rotate the ship's propeller and move the ship through water. They usually burn diesel or heavy fuel oil, and may be able to switch between the two. There are many propulsion settings for motor boats, some including some engines, propellers, and gearboxes.
Smaller engines, but still large propelled electric generators that provide power to the ship's electrical system. Large vessels typically have three or more synchronized generators to ensure smooth operation. The combined output of the ship generator is well above the actual power requirement to accommodate the maintenance or loss of a single generator.
On steamers, power for electricity and propulsion are provided by one or more large boilers that give rise to an alternative name boiler room . High vapor pressure from the boiler is used to drive reciprocating or turbine engines for propulsion, as well as turbo generators for electricity. In addition to propulsion and auxiliary machines, the typical engine room contains many smaller engines, including generators, air compressors, feed pumps, and fuel pumps. Currently, these machines are usually powered by small diesel engines or electric motors, but may also use low-pressure steam.
Engine cooling
The machine (s) obtain the required cooling of the liquid-to-liquid heat exchanger connected to fresh seawater or diverted for recirculation through a seawater tank in the engine room. Both inventories draw heat from the engine through the cooling and oil channels. The heat exchanger is inserted so that the oil is represented by a yellow mark on the pipe flange, and depends on the type of gasket paper to cover the mating face of the pipe. Sea water, or salt water, is represented by green markings on flanges and internal cooling is represented by blue markings on flanges.
Thrusters
In addition to this equipment is the ship's thruster system (on a modern ship equipped with this equipment), usually operated by electric motors controlled from the bridge. These propellers are mounted laterally vanes that can suck or blow water from port to right (ie left to right) or vice versa. They are usually only used in maneuvers, eg. docking operations, and are often prohibited in strict limits, eg. drydocks.
Thrusters, like the main propellers, can be reversed by hydraulic operations. The embedded small hydraulic motor rotates the propeller up to 180 degrees to reverse the direction of the thrust. The variant on this is the azipod, which is a propeller mounted in rotary pods that can rotate to direct impulse in all directions, making smooth steering easier, and allowing the vessel to move sideways to the dock, when used in conjunction with the booster arc.

Security
Fire prevention measures
The engine room is hot, noisy, sometimes dirty, and potentially dangerous. The presence of combustible fuels, high voltage electrical equipment (HV) and internal combustion engines (ICE) means that serious fire hazards exist in the engine room, continuously monitored by ship technical staff and various monitoring systems.
Ventilation
The engine room was separated from a fire-fighting chamber linked to a warship from the 1880s through the 1960s. If one is damaged by action, the engine-related chamber can get steam from another fire-fighting chamber.
