Placing the cooling radiator section in seawater rather than ambient air allows for the radiator to be smaller. The engine's cooling water may be used directly or indirectly for heating and cooling purposes of the ship. The Stirling engine has potential for surface-ship propulsion, as the engine's larger physical size is less of a concern.
Main engine deck of a cargo vessel Location of a ship's engine room on a bulk carrier Engine room of the Mercy Ship Caribbean Mercy in 1997. Her propulsion diesel is an MAK. EMD diesels in the engine room of the Research Vessel Davidson circa 2002. On a ship, the engine room (ER) [1] is the compartment where the machinery for marine propulsion ...
Period cutaway diagram of a triple-expansion steam engine installation, circa 1918. This particular diagram illustrates possible engine cutoff locations, after the Lusitania disaster and others made it clear that this was an important safety feature. A marine steam engine is a steam engine that is used to power a ship or boat.
The holds are topped by hatch covers, onto which more containers can be stacked. Many container ships have cargo cranes installed on them, and some have specialized systems for securing containers on board. The hull of a modern cargo ship is a complex arrangement of steel plates and strengthening beams.
Tankers generally have cofferdams forward and aft of the cargo tanks, and sometimes between individual tanks. [3] A pumproom houses all the pumps connected to a tanker's cargo lines. [1] Some larger tankers have two pumprooms. [1] A pumproom generally spans the total breadth of the ship. [1]
Therefore, a 140-short-ton (130 t) [12] vertical triple expansion steam engine, of obsolete design, was selected to power Liberty ships because it was cheaper and easier to build in the numbers required for the Liberty ship program, and because more companies could manufacture it. Eighteen different companies eventually built the engine.

Schematic showing various cargoes loaded, trim, and list. Monitoring systems that do not use computers are still often seen. The design and layout of an individual cargo control room is determined by the ship's design, owner's requirements and the capabilities of the shipyard in which the ship is built. [3]
