The magnetic field-producing component of an electrical machine.

The metal or alloy added in making a welded, brazed, or soldered joint.

A rounded corner created at an inside angle of a structure or casting.

Continuous coating made by the application of one or more coats onto the surface. A “wet film” is the one that has just been applied, before solvent evaporates.

Photographic film used to measure exposure to ionizing radiation for purposes of personnel monitoring.

The thickness of the paint or paint system.

A device used for mechanical separation of solid contaminants from a liquid or a gas. Fine mesh filters are used to remove the smallest particles of dirt from oil before the oil enters the finely machined engine parts.

A filter with an automatic cleaning function. Back flashing is carried out by reversing the fuel flow to remove contaminants from the surface of the filter.

Filtration can be defined as the process of collecting solid particles from a fluid by passing the fluid through a filter medium where the particles are retained.

A small part of a large continuous structure which is investigated with regards to its loading. Displacements, stresses and strains can be determined at the nodes where the various elements meet and the whole structure is thus analysed.

The method of analysis of ship structures developed in 1960s. This allows to apply loads in the most realistic way and to analyse stresses with sufficient accuracy even in very complex structures.

Fire is the result of a combination of three factors; a substance that burns, an ignition source, and a supply of oxygen.

A plan providing crucial information for rapid and efficient action of the vessel’s crew during a fire.

A device which can detect a fire, and provide a signal to an alarm circuit. Fire detectors can be operated by smoke, flames, and heat, or any combination of these factors.

“A” class divisions – Bulkheads and decks constructed of steel or other equivalent material, suitably stiffened, and designed to withstand and prevent the passage of smoke and flame for the duration of the one-hour standard fire test.

A sea water supply system for fire hydrants. It consists of sea inlets, suction piping, fire pumps and a distributed piping system supplying fire hydrants, hoses and nozzles located throughout the vessel.

Fixed foam/powder/water cannon shooting fire-extinguishing agents on the tank deck, manifold etc.

An inspection through the vessel carried out by a crewmember on the watch at certain intervals so that an outbreak of fire may be promptly detected; mandatory in vessels carrying more than 36 passengers.

The fire point of a fuel is the lowest temperature at which the vapour of that fuel will continue to burn for at least five seconds after ignition by an open flame of standard dimension.

Usually centrifugal pumps with flat or very shallow head/capacity curves.
