The company official from the ship operator who will be responsible for developing, maintaining and enforcing the company security policies as set out in the Ship Security Plan.

An internal space separated by bulkheads or plating.

The subdividing of the hull by transverse watertight bulkheads so that the ship may remain afloat under some conditions of flooding.

An instrument using either a magnet or a gyroscope for steering or taking navigational bearings.

The process of placing magnets and iron masses so as to neutralize the effect of magnetism existing or induced in the ship hull...

Indicates whether different goods can be safely stowed together in one cargo space or in adjacent holds.

In business, a competitive advantage is the attribute that allows an organization to outperform its competitors. A competitive advantage may include access to natural resources, such as high-grade ores or a low-cost power source, highly skilled labor, geographic location, high entry barriers, and access to new technology.

The number of officers and crew employed upon a vessel for its safe navigation and operation.

A joint root condition in a groove weld in which weld metal extends through the joint thickness.

A compliant tower is a fixed rig structure normally used for the offshore production of oil or gas.

A firetube boiler which can generate steam by oil firing or the use of diesel engine exhaust gas.

A composite material is a material which is produced from two or more constituent materials.

Compressed-air energy storage (CAES) is a way to store energy generated at one time for use at another time using compressed air.

In thermodynamics and fluid mechanics, the compressibility (also known as the coefficient of compressibility or, if the temperature is held constant, the isothermal compressibility) is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.

In mechanics, compression is the application of balanced inward ("pushing") forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions.

A steel bar fitted on hatch coaming upper plate against the seal, providing a weathertight joint.

Internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel, which is injected into the combustion chamber during the final stage of compression.

An internal cumbustion engine where air is drawn into a cylinder and in the compression cycle fuel injected into the cylinder causing the mixture to detonate.
