A valve arrangement where the liquid flows through a hole in a central plug.

The Cockcroft–Walton (CW) generator, or multiplier, is an electric circuit that generates a high DC voltage from a low-voltage AC or pulsing DC input.

Similar to the counter-current type, but the gasification agent gas flows in co-current configuration with the fuel.

In the cocurrent flow exchange mechanism, the two fluids flow in the same direction.

The CORAL PRINCESS built in 2002 at Chantier de l’Atlantique is P&O first CODAG cruise liner.

Position of container on board a ship is defined by three numbers: bay number, row number and tier number.

The Code first adopted by IMO in 1965 and updated regularly since then by the Subcommittee on Containers & Cargoes. Since 1991, the BC Code has been included in Chapter VI of the 1974 SOLAS Convention.

A factor used as a multiplier of the quantity or variable, being considered.

A ratio of useful heating (or cooling) to provide work. Higher COP's indicate higher efficiency.

Coefficients used in naval architecture: block coefficient, midship section coefficient, prismatic coefficient and waterplane coefficient.

An isolating space arranged so that compartments on each side have no common boundary; a cofferdam may be located vertically or horizontally.

A system that generates electricity and by collection of waste energy in that process can produce other energy resources, ie hot water or steam generated from the heat recovered from the engine exhaust system.

The cruise liner MILLENNIUM built by Chantier l’Atlantique for Royal Caribbean/Celebrity Cruises has pioneering machinery installation. For the first time in merchant ships for some 25 years, gas turbines are used for the primary power.

Cogging torque of electrical motors is the torque due to the interaction between the permanent magnets of the rotor and the stator slots of a Permanent Magnet (PM) machine.

A heat exchanger used to transfer energy from one source to another.

Purpose-built panels developed and patented by the Finish ship owner Langh Ship in order to accommodate steel coils on a general cargo ship.

In electrical engineering, coil winding is the manufacture of electromagnetic coils.
