Offshore wind energy (offshore wind power) is the conversion of wind's kinetic energy into electrical energy. Uniform and high speeds of wind can be harnessed in offshore environment since it accounts to nil obstruction to wind force. Multiple windmills together constitute to a wind farm. These farms are constructed in the water bodies usually oceans to harvest the energy of wind and convert it into electrical energy.
The offshore wind installations reduces the impact on real estate as in onshore installations. Moreover, wind speed is uniform and consistent in offshore installations, which increases the efficiency of electricity generation. Thus, the offshore wind energy is highly attractive and more promising in terms of power generation and grid connections.
Some of the restraining factors of offshore wind installations are wind turbines are exposed to high humidity and salt contents, which affects service life of components due to corrosion, oxidation and increased repair and maintenance costs. In general, the offshore installation costs are much higher than onshore. The repair maintenance and overhauling operations are also high cost and time consuming as it requires expensive marine operations involvement and are comparatively dangerous. The offshore wind farms operate at high speeds compared to onshore wind farms, hence offshore turbines are more susceptible to high rate of wear and tear, maintenance and repair of moving parts.
In the early 2017, Denmark has come up with new recycling process of offshore wind turbine blades, made up of fiberglass. When the wind turbine is de-commissioned, the blades may fall off to the landfill area where it may take many years to decompose. The blades can now be recycled and applied as sound barriers of vehicular traffic along major roads.
