Case of death or serious injury to a person in an accident or shipping disaster, also used about a distressed vessel.

Catalysis is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst.

A catalytic cycle is a multistep reaction mechanism that involves a catalyst.

A vessel with two hulls and a deck structure between them.

The world’s fastest ferry FRANCISCO was delivered in 2013 to the Argentinean owner Buquebus from the Australian shipbuilder Incat Tasmania Pty Ltd.

Term used in the offshore industry for a major hydrocarbon release that results from uncontrolled developments and that may lead to serious danger to personnel.

The curve produced by a uniform, flexible wire or chain when suspended by its ends. Anchor chains from a buoy or a towing wire between vessels will take this shape.

The single point mooring system. A catenary anchor leg mooring system consists of a large buoy anchored by catenary mooring lines.

An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric trains, trolleybuses or trams.

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

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.

A cathode is an electrode through which conventional current leaves an electrical device.

Cathodic protection is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.

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.

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

A method of thermal energy storage where unused mines and purpose built caverns can be used for thermal energy storage. To be economical they need to be close to industrial or community areas.

Cavitation is a phenomenon in which the static pressure of the liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid.

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.

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

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