A fishing vessel that employs a long main line supported by floats with shorter lines attached to it with baited hooks at their lower point. Shooting of the long line is done over the stern.

Fore-and-aft structural shape or plate members attached to the underside of decks, flats, or to the inner bottom, or to the inboard side of the shell plating, in association with widely-spaced transverses, in the longitudinal framing system.

A record book that the master of a ship is required to fill in during a voyage. Originally it was a book for recording readings from the log.

A device, which measures the distance travelled and the speed of a ship moving through the water.

The process of developing the size and shape of the components of the ship hull structure from the designed lines.

A region of a canal or river which can be enclosed by gates. It is then filled or emptied in order to raise or lower ships whilst afloat.

The finding of ships, aircrafts or persons in distress.

Passenger vessels over 500GT and cargo ships over 2000GT with the keel laid after July 2002 will have to be fitted with local fire protection in machinery spaces in addition to the CO2 system.

A ship at sea encounters many types of loads and forces simultaneously, such as wave-induced bending and shear torsion, impact of waves on the sides, deck and bottom, static loads from cargo and the sea, as well as sloshing.

The rate of loading of a particular type of shore-based equipment (measured in tons/hour).

The loading of cargo or ballast “over the top” through an open-ended pipe or by means of an open-ended hose entering a tank through a hatch or other deck opening, resulting in the free fall of liquid.

An instrument by means of which it can be easily and quickly ascertained that the still-water bending moments and shear forces will not exceed the specified values in any load or ballast condition.

Alternate hold loading condition, Heavy cargo, such as iron ore, is often carried in alternate cargo holds on bulk carriers.

Transfer units between ship and shore for discharge and loading oil or any liquefied gas; there are articulated all-metal arms (hard arms) or a combination of metal arms and hoses.

According to SOLAS Convention every passenger ship regardless of size and every cargo ship having a length L of 24m and upwards, must be provided with such information...

Shore-based equipment used to load the holds of a cargo ship (e.g. conveyor belt).

Ships must have a load line mark located amidships on both sides to indicate the maximum allowable draught under specified conditions (geographical and seasonal).

see International Convention on Load Lines, 1966.

Although steam turbine propulsion has served LNG tankers well for a couple of decades, this type of propulsion is relatively inefficient and expensive to operate.

Built by Hyundai Heavy Industries in Ulsan, the BRITISH EMERALD is the LNG tanker with dual-fuel diesel-electric propulsion. At 155,000 cubic metres she is one of the largest LNG carriers to date.
