- Cable laying – When laying off, the primary need is to control the speed and tension at which the cable departs the ship. This control is done by means of cable machines:

Installation and maintenance of a submarine cable is a complex operation requiring sophisticated tools. The primary cable handling equipment of a typical cable-layer is designed...

The cable diverter is sited aft of the cable drum engine and ensures the proper cable deflection and retainment during pick-up operations. This will ensure that the cable fleeting is maintained over 180° of the drum-fleeting ring.

Arrangement of two or more cables laid parallel and touching one another.

1. A rope or chain connecting a vessel to the anchor. 2. Wire or rope primarily used for mooring a ship.

A compartment in the accommodation area provided for a passenger or member of the ship complement. With most cabins having their own private toilets, the location of these is important.

Spaces not normally subdivided in any way and extending to either a substantial length or the entire length of the ship in which goods can be loaded and unloaded normally in a horizontal direction.

Trailer trestles, support jacks, speedlash, wheel chocks.

An equipment fitted on ro-ro vessels to ensure access and movement of vehicles on board. A typical cargo system consists of a stern ramp/door, internal ramps or elevators and flood control doors.

Abbreviation for a vessel designed to carry vehicles, so arranged that the vehicles may be loaded and unloaded by being rolled on or off on their own and/or auxiliary wheels, via ramps fitted in the sides, bow or stern of the vessel.

A hybrid vessel equipped with hatch covers and cargo access facilities characteristic for ro-ro vessels.

The main feature of the three ro-lo vessels delivered by Gdynia Shipyard is multi-access system designed by MacGREGOR.

A low-profile vessel designed for navigation in coastal waters and river/sea trading. As a consequence, a river/sea vessel features a shallow draught in loaded condition as well as low overhead clearance in ballast condition.

A conducting pipe connecting sub-sea wellheads, templates or pipelines to the equipment located on a buoyant or fixed offshore structure, (ABS).

The distance above the keel that a tangent to the bottom at or near the keel cuts the line of maximum beam amidships.

A new type of drive developed by General Dynamics Electric Boat of Groton, USA. This drive is more compact and has several features that differ significantly from other pods available today.

Built at the Merwede Shipyard in Netherlands, the SEVEN OCEANS is intended for installation of rigid pipes up to a diameter of 16’’ on the ocean floor in depths up to 3000m using the reel-lay method.

Any arrangement to control and turn away a fluid from its main flow path.

see International Convention for the Control and Management of Ship’s Ballast Water and Sediments (BWM Convention).

When the ship floating at rest in still water is inclined by an external force to a small angle fi, the centre of gravity G will remain in the same position but the centre of buoyancy moves towards the submerged side.
