An offshore wind turbine is a turbine that generates electricity from wind blowing across the sea. Fixed-support and floating are the two main types of offshore wind turbines.
Due to the higher wind-harnessing capability, horizontal-axis wind turbines are preferred over vertical-axis wind turbines for offshore wind harnessing.
The global operational offshore wind capacity was reported to be around 64 GW in 2022. In the coming years, offshore wind power is expected to grow significantly to meet climate and energy targets, as well as ensure energy independence.
Wind turbine makers have been adopting powerful technologies to make offshore wind turbines with larger rotors to lower risk and increase energy production for projects at sea.
Furthermore, a robust supply chain and standardized processes are enabling wind turbine companies to reduce the time to market of offshore wind turbines.
