A mobile off shore unit primarily intended for the installation, maintenance and repair of wind turbines in off shore and coastal waters, including pile driving, tower installation, and nacelle and blade installation.

A preventative maintenance process to enhance the operation and longevity of machinery.

A device that converts the winds knetic energy into electricity.

The disturbance of wind speed and direction due to obstacles.

Measures wind direction and communicates with the yaw drive to orient the turbine properly with respect to the wind.

In fluid dynamics, wind waves, or wind-generated waves, are water surface waves that occur on the free surface of bodies of water.

A windcatcher (wind tower, wind scoop) is a traditional architectural element used to create natural ventilation and passive cooling in buildings.

A machine designed to hoist or lower an anchor. It consist of a horizontal barrel that is fitted with gear-like projections (cable lifter) that engage the links of the anchor chain.

Each windlass is to be tested under working conditions after installation onboard.

WindMade is a global (Brussel's based) consumer label for companies, events and products using wind power in their operations or production.

Windows are not allowed to be used in superstructures or in the ship shell, but only in deckhouses. However, if the deckhouse protects an opening in the deck, deadlights are required.

Winter diesel fuel refers to diesel fuel enhanced to prevent it from gelling in cold weather conditions.

A wire is a single usually cylindrical, flexible strand or rod of metal.

Wire gauge is a measurement of wire diameter.

A ring mounted on the propeller hub in order to protect the sterntube aft seal.

Wireless power transfer or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link.

Wireless slip rings do not rely on the typical friction-based metal and carbon brush contact methods that have been employed by slip rings since their invention, such as those explored above.
