The point at which the total weight of all the items which make up a vessel total weight may be considered as concentrated.

The geometric centre of the waterplane on which a vessel floats. A vessel pitches, or rotates (about a transverse axis) through this point, when moved by an external force.

The centre of gravity of the displaced water. That is, the geometrical centre of the underwater part of the ship.

It consists of a suitably constructed tank which is maintained automatically under a vacuum by air exhausting units, with connections leading to the tank from each of the pumps concerned.

Most cooling systems are made as central cooling ones, which means that there is only one or two large plate heat exchangers equipped with titanium plates.

A control station in which the following control and indicator functions are centralized:

An established unit used for the measurement of kinematic viscosity. The accepted SI unit is m2/s and 1cSt = 10-6 m2/s.

The void space running in the midships fore and aft lines between the inner bottom and shell plating forming a space for ballast, bilge and/or fuel lines.

According to The Motor Ship May 1996 The self-loading/discharging cement carrier KEDAH CEMENT II was built by Pan-United Shipyard, Singapore.

A single-skin or double-skin bulk carrier provided with a cement loading and discharging plant.

Suspended metal ceilings are suitable for public spaces (restaurants, shops, and theatres), cabins and corridors, storage rooms and offices.

A facility used for propeller cavitation tests. This is a vertical water circuit with large diameter pipes. A parallel inflow is established.

Cavitation tests are performed in a cavitation tunnel using a dummy afterbody model and simulated full-scale wake-field or a full model.

A non-dimensional parameter for the dynamic pressure in a fluid; also to estimate the cavitation probability in a fluid.

The erosion of material, for example backside of the blades usually attributed to the collapse of cavitation bubbles.

Degradation of metal surfaces, characterized by pitting occurring when very turbulent fluids come into contact with metal surface, and associated with the formation and collapse of cavities in the liquid at solid – liquid interface.

Plastic deformation of weld and base metal surfaces by mechanical means to seal or obscure discontuities.

A narrow, raised platform or pathway used for passage to otherwise inaccessible areas on a ship permitting fore and aft passage when the main deck is awash.

The anti-fouling system based on the electrolytic principle. It consists of copper and aluminium anodes which are fed with an impressed electrical current from a control panel.

SeaFrance ro-ro passenger ferry RODIN has become the largest and fastest ferry to operate on the Dover-Calais route.
