The top strake of a ship side shell plating.

A type of the floating crane.

Shell and tube heat exchangers consist of a series of tubes which contain fluid that must be either heated or cooled.

Doors in the side shell can be seen on almost every type of ship and are used for various duties. The most common ones are for passengers, pilot entry, and for bunker hoses

A plan showing the seams and butts, thickness and associated welding of all plates comprising the shell plating, framing, etc.

The plates forming the outer side and bottom skin of the hull. The shell plating is of crucial importance to the longitudinal strength of the ship structure.

A continous deck above the freeboard deck.

The MacGREGOR Sherlog is a type-approved, ultrasonic testing system for verification of tightness of hatch covers, doors, ramps and windows.

A shielded cable or screened cable is an electrical cable of one or more insulated conductors enclosed by a common conductive layer.

An arc welding process with an arc between a covered electrode and the weld pool.

Protective gas used to prevent or reduce atmospheric contamination.

Wooden planks which are used to partition holds to prevent the movement of loose bulk cargoes. They are fitted fore and aft on the centreline in the way of hatches.

Granular cargoes that adversely affect the stability. During roll, the granular material, such as grain, coal, etc., stays in place until the heel angle exceeds the angle of repose.

A thin strip of metal which is used to adjust the clearance between mating parts, e.g. the two halves of a big end bearing.

A sea-going or coastal vessel which is not propelled by oars.

The development of a new ship design is carried out in three steps.

A ship lifting system. The ship elevator includes a number of hydraulic lift/lower chain jack stations on each side of the elevator platform.

Passenger ships of 100 gt and above and cargo ships of 300 gt and above are to have an identification number (IMO number) which is to be shown on the statutory certificates.

Hydrodynamic test centres equipped with model testing tanks and propulsor testing facilities to perform experiments on hull and propulsor design.

A ship at sea moves in six degrees of motion: heave, sway, surge, roll, pitch and yaw. The first three are linear motions.
