Offshore wind turbines are alike to onshore wind turbines and utilize significantly similar technology. The only major difference as far as power capture is concerned is that they are commonly bigger. As with onshore machinery, offshore are straight-axis wind turbines with three-bladed rotors.

Drive-trains for offshore wind turbines are undistinguishable from those utilized on the 
ground too; some utilize gearboxes and comparatively high-speed generators, while others are fortified with direct drive between the turbine rotor and the generator. 

Towers are of alike construction. Offshore wind turbine towers are usually constructed from tubular steel sections. Though, foundations for offshore wind turbines are significantly different from those used onshore.

What are the Advantages of Offshore Wind Farms?

Offshore wind rapidity has the potential to be quicker than on land. Small surges in wind speed produce huge surges in power production: a turbine in a 20-mph wind can produce twice as much power as a turbine in a 15-mph wind. Faster wind speeds offshore mean much more power can be produced.

Offshore wind speeds tend to be more solid than on the ground. A more solid supply of wind resources is a more dependable source of power.

Numerous coastal parts have very high-power requirements. Half of the United States’ populace survives in coastal zones, with concentrations in key coastal metropolises. Constructing offshore wind farms in such locations can aid to fulfill those power requirements from neighboring sources.

Offshore wind farms have numerous of the same benefits as ground-based wind farms – they offer renewable power; they do not consume water; they offer a domestic power source; they generate jobs; and they do not release environmental contaminants or GHG.

Hence, the execution of supportive government rules in several nations, enormous expenditure being made in renewable power sources, and continuous technological improvements in offshore plants, are the major factors contributing to the growth of the market.
