An internal combustion engine operating within the range from 250 rev/min to about 1200 rev/min.

Electric power unit equal to one million watts

Electric power unit equal to one million watts used for one hour.

A Megohmmeter or insulation resistance tester is a special type of ohmmeter used to measure the electrical resistance of insulators.

Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid.

The melting point of a substance is the temperature at which it changes state from solid to liquid.

Wärtsilä Hamworthy’s MBR technology is an advanced wastewater treatment process based on biological degradation and membrane separation.

Built in 1999 by Hanjin Heavy Industries Co Ltd, Korea, LNG tanker HANJIN MUSCAT has four cargo tanks contained in a complete double-hull structure, which includes ship sides and bottom, transverse bulkheads and upper deck trunk.

The membrane technology was developed by the naval engineering firms Gaz Transport and S.N. Technigaz for the transport of liquid methane by sea.

Built in Japan at the Namura yard, the methanol carrier MILLENNIUM EXPLORER is equipped with the world largest ship-based nitrogen generator system.

Membrane systems exploit the double hull of the ship as the supporting structure on which a cryogenic liner – performing the two functions of gas tightness and thermal insulation – is applied.

Agreements on port state control signed in several regions of the world by the coastal states ; 1982 Paris MOU for the European region, 1992 Latin America agreement, 1993 Tokyo MOU for the East Asia region, etc.

Mercury-wetted slip rings, noted for their low resistance and stable connection use a different principle which replaces the sliding brush contact with a pool of liquid metal molecularly bonded to the contacts.

The Rolls-Royce’ s podded propulsor developed by Kamewa and Alstom and available from 5 to 25MW.

Mesoscale meteorology is the study of weather systems smaller than synoptic scale systems but larger than microscale and storm-scale cumulus systems.

A light line attached to the end of a main mooring line and used to assist in heaving the mooring to the shore or to another ship.

Dinning room for officers or crew.

When a ship floating at rest in still water is inclined by an external force to a small angle fi, the centre of buoyancy shifts from B to the new position – Bfi.

The vertical distance between G and M is referred to as the metacentric height. The relative positions of vertical centre of gravity G and the initial metacentre M are extremely important with regard to their effect on the ship’s stability.

A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well.
