BUNKERS - fuel consumed by the engines of a ship; Compartments or tanks in a ship for fuel storage. • BARGE - flat-bottomed boat designed to carry cargo on inland waterways, usually without engines or crew accommodations. Barges can be lashed together and either pushed or pulled by tugs, carrying cargo of 60,000 tons or more.
NAUTICAL MILE - distance of one minute of longitude at the equator, approximately 6,076.115 feet. The metric equivalent is 1852 meters. • KNOT - unit of speed in navigation which is the rate of nautical mile (6,080 feet or 1,852 meters) per hour. • HULL - shell or body of a ship.
QUAY - A structure attached to land to which a vessel is moored. • ABAFT - A point beyond the midpoint of a ships length, towards the rear or stern. • AFT - in, near, or toward the stern of the vessel.
ASTERN - A backward direction in the line of a vessel's fore and aft line; Behind. If a vessel moves backwards it is said to move astern; Opposite to ahead. • AT SEA - in marine insurance this phrase applies to a ship which is free from its moorings and ready to sail.

Also called breadth. • BOW - the front of a vessel. • BRIDGE - used loosely to refer to the navigating section of the vessel where the wheel house and chart room are located; Erected structure amidships or aft or very rarely fore over the main deck of a ship to accommodate the wheelhouse.
DANGEROUS CARGO - all substances of an inflammable nature which are liable to spontaneous combustion either in themselves or when stowed adjacent to other substances and, when mixed with air, are liable to generate explosive gases or produce suffocation or poisoning or tainting of foodstuffs.
Bunkering Bunker: A Container for Fuel : To Put Fuel into the Bunker
TYPE OF FUEL USED FOR MAINMACHINARIES ON BOARD A VESSEL. • MAIN ENGINE:- FO, DO. • GENERATORS (AUX. ENGINES):- DO, FO. • AUXILIARY BOILER :- DO, FO. • EMERGENCY GENERATOR / LIFE BOAT ENGINES / EMERGENCY FIRE PUMP ENGINES / EMERGENCY AIR COMPRESSOR ENGINE:- GO / DO. • When sensitive cargoes are being carried and IG generators are fitted they also use gas oil
