Anchor Handling, Tug, Supply Vessel SIEM PEARL, based on Wärtsilä Ship Design’s VS491 CD design, was delivered in 2009 by Kleven Yard in Ulsteinvik (Norway).

Charted marks such as buoys, beacons, lights, radio beacons and the like.

According to HSB International September 2004. The sophisticated light tender RELUME was built by the Dutch shipbuilding group Damen for Middle East Navigation Aids Service (MENAS)...

The vessel specially equipped to maintain and repair navigation buoys, beacons, automatic lighthouses, etc.

An air basin is an area within a ring or partial ring of mountains that in the absence of winds holds air and smog within the area.

A pneumatic device for producing air for higher pressure work, compressed air is fed to a pressure vessel where it will be stored until used.

Air conditioning is the process of removing heat and controlling the humidity of the air within a building or vehicle, in order to achieve a more comfortable interior environment.

A typical recirculating system contains a fan to produce the airflow through the system, a cooling coil where the heat from the air is transferred to the cooling medium...

The airside of the scavenge air cooler is cleaned by a chemical fluid injected into a spray pipe arrangement. Polluted cleaning agent returns through a filter, to the chemical cleaning tank.

A heat exchanger used to cool and, therefore, increase the specific density of air prior to combustion in an engine.

Air cooling is a method of dissipating heat.

A craft with the whole or a significant part of its weight supported, whether at rest or in motion, by a continuously generated cushion of air with its effectiveness dependent on the proximity of the surface over which the craft operates.

The density of air or atmospheric density is the mass per unit volume of Earth's atmosphere.

The vertical distance from the waterline to the highest fixed part of a vessel.

A unit used to remove moisture from control air. It may use a refrigerant drier or a desiccant.

Thin-walled piping or ducting (circular or rectangular) used exclusively to conduct air.

A particulate air filter is a device composed of fibrous, or porous materials which removes solid particulates such as dust, pollen, mold, and bacteria from the air.

Air guns are devices that rapidly release compressed air into water creating the effect of explosion. To provide sufficient energy for geophysical surveys, compressors generating extremely high pressures are required.

An air handler, or air handling unit, is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.

A heat exchanger, which uses steam, water or electricity to increase the air temperature.
