The wet sulfuric acid process is a key gas desulfurization processes. It is an efficient process for recovering sulfur from various process gases in the form of commercial quality sulfuric acid (H2SO4), with simultaneous production of high pressure steam.

A new technology using a remotely-operated vehicle (ROV) for hull survey developed by Det Norske Veritas.

The NOx reduction technology developed by Wärtsilä. Pressurized water is added to the intake air after the turbocharger to reduce the combustion temperature and thereby the formation of NOx.

For a ship floating at a given waterline, the wetted surface is the total area of her outer surface in contact with the surrounding water.

Wetting current is the minimum electric current needing to flow through a contact to break through the surface film resistance at a contact.[1] It is typically far below the contact's nominal maximum current rating.

An enclosed space in which the main steering wheel, controls, engine room telegraph, etc., are located.

In electric power transmission, wheeling is the transportation of electric energy (megawatt-hours) from within an electrical grid to an electrical load outside the grid boundaries.

Any sound signalling appliance capable of producing the prescribed blasts.

A tin-based alloy with amounts of lead, copper and antimony. It may also be a lead- based alloy with antimony.

Clean products such as benzene, kerosene and gasoline.

Also known as an "interconnection" in the USA is a large scale power grid that spans large areas and countries that are electrically connected and operating under a synchronised frequency.

Towed seismic spread with significant lateral separation. Normally, it requires the use of paravanes.

Wide-area damping control is a class of automatic control systems used to provide stability augmentation to modern electrical power systems known as smart grids.

A machine with a drum on which a rope, cable, or chain for hauling, pulling, or hoisting can be wound.

Wind is the flow of gases on a large scale.

The strakes of side shell plating between the ballast and the deepest load waterline.

A tool used in the wind energy industry to simulate wind flow over terrain and estimate the long-term power production of wind turbines and wind farms.

Power that is generated solely from the wind energy to drive electric generators by wind turbines. Wind is a renewable energy source.

A group of wind turbines grouped together in one location for the generation of electricity.

A wind monitoring process that allows fast startup of engine driven generators in anticipation of diminishing wind strength where wind power is utilised.
