Final turbine installed on world´s largest offshore wind farm
Ørsted has announced that the final wind turbine of 174 turbines has been installed at Hornsea One project in the North Sea. Once complete, the site will be the world's first offshore wind farm to be able to generate over 1GW of electricity - enough to power well over one million UK homes.
The component loadout took place at Siemens Gamesa Renewable Energy's factory in Hull, where the majority of blades were constructed, and the components were then transported 120km out to sea. The turbines were transported by two specialist vessels: The Bold Tern, owned by Fred.Olsen Windcarrier, and DEME Group's Sea Challenger. Both are installation vessels which jack up in the sea to provide a sturdy base for lifting.
Four turbines were loaded on to the vessel each time. The main components are a steel tower, three turbine blades and a nacelle which houses all generation components for the turbine. On average, it takes around 12 hours of precision working to install a turbine in full.
Standing 190m above sea level and with three 75m long blades, each 7 MW turbine will be able to power a UK home for over a day with each single rotation.
The wind farm is located in the North Sea more than 100km from the Yorkshire coast.
Now the final turbine is installed, the project will undergo a period of commissioning, and will be officially inaugurated in 2020 as the world's largest offshore wind farm.
Hornsea 1 is 50/50 joint venture between Ørsted A/S and Global Infrastructure Partners (GIP).
