The angle formed by the centerline of the vessel and the tangent to the design waterline at the forward perpendicular.

The ship is equipped with an electro-hydraulic combined anchor windlass/mooring winch. The windlass is a 49.5t capacity device rated at 9 m/min, and the mooring winch is 20t capacity device rated at 15 m/min with two drums and two sets.

Low-noise anchoring and mooring equipment are valued by Carnival Cruise Lines, whose 70,400gt ELATION and PARADISE feature two sets of Rauma electric combined mooring winch/windlass units on the forward mooring deck.

Rauma Brattvaag has provided anchoring and mooring systems for 140,000m3 LNG tankers built by Daewoo for Bergesen ASA.

Each windlass shall be tested under working conditions after installation on-board to demonstrate satisfactory operation. Each unit is to be independently tested for braking, clutch functioning...

A recess in the bow plating large enough to accommodate the anchor so that there is no projection outside of shell plating.

A heavy chain used for holding a vessel at anchor. The total length of chain is to be divided in approximately equal parts between the two bower anchors.

A heavy forging or casting shaped to grip the sea bottom, and by means of a cable or rope, holds a ship or other floating structure in a desired position regardless of wind and current.

Analogue components generate time-continuous outputs (volts, pressure, and so forth) to manipulate process inputs and which operate on continuous signals from instrumentation measuring process variables (position, temperature, and so forth).

The maximum displacement of a varying quantity, measured from some datums.

The ratio of output to input magnitude in a device which is designed to produce an increased value output.

Amount of unreacted ammonia emitted from a control equipment such as electrostatic precipitator, selective catalytic reduction (SCR) or selective non-catalytic reduction process.

Noxious, pungent gas, extremely soluble in water and alcohol. It is used as a refrigerant. Further Ammonia is used as feed stock in e.g. fertilizer production and several other industries.

1. A nautical term, which refers to the longitudinal centerline of a ship. 2. In ship construction amidships is in the middle of the length (L).

Environmental conditions that the crew is exposed to during periods of work, leisure or rest.

Parameters such as barometric pressure, engine room and seawater temperatures and relative humidity to be taken into account while designing ship’s machinery.

A copper aluminium alloy containing 4-11% of aluminium and other elements for particular properties. It is used for propulsors, valve fittings and other applications where corrosion resistance is important.

Brass containing up to 6% aluminium in order to improve resistance to corrosion.

Aluminium alloyed with materials such as copper, manganese, silicon or magnesium, to improve their strength.

A light metal of a good resistance to atmospheric corrosion. It is used as the base metal for light alloys.
