A winch with a drum which is used for hauling in or letting the mooring wires go. A warp end is also fitted to assists in moving the ship.

The brake is the heart of the mooring winch, since the brake secures the drum and consequently the mooring line at the shipboard end.

The percentage of the minimum breaking load (MBL) of a new mooring rope or wire it carries, at which the winch brake is designed to render.

Mooring winches secure the shipboard end of mooring lines, provide for adjustment of the mooring line length and compensate for changes in draft and tide.

The power source for the winch systems can be low-pressure hydraulic, high-pressure hydraulic, frequency-converter drive or pole-change electric drive.

The LNG cargo containment system developed by Moss Rosenberg Verft. The system features self-supporting spherical tanks connected at the equator to a single cylindrical supporting skirt, the lower portion of which is welded to the ship structure.

A casing provided according to the location of the motor, e.g. flameproof, drip-proof, hose-proof.

A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up.

An electronic controller for starting a motor from rest, accelerating it up to normal running speed and also stopping it.

A motor–generator (an M–G set) is a device for converting electrical power to another form.

The maximum horizontal breadth of any frame section. The term breadth and beam are synonymous.

The perpendicular distance in a transverse plane from the top of the flat keel to the underside of deck plating at the ship side.

Lines defining the geometry of a hull as a surface without thickness; structural members are related to the moulded lines according to the standard practice, e.g. the inside surface of flush shell plating is on the moulded line.

Mixed oxide fuel, commonly referred to as MOX fuel, is nuclear fuel that contains more than one oxide of fissile material, usually consisting of plutonium blended with natural uranium, reprocessed uranium, or depleted uranium.

A coarse strainer with a straight tailpipe down to the bilge.

Also known as epicyclic gear train consists of two gears mounted so that the center of one gear revolves around the center of the other used in wind turbines.

Power plants that utilise more than one fuel source.

Vessels developed for monitoring, supporting and subsea operation services.

Multi-junction solar cells are solar cells with multiple p–n junctions made of different semiconductor materials. Each material's p-n junction will produce electric current in response to different wavelengths of light.

In the physical sciences, a multilayer or stratified medium is a stack of different thin films.
