Orsted announced that the final of 174 wind turbines has been installed at the world's largest offshore wind farm Hornsea 1. 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 wind 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 a proud 190m above sea level and with its three 75m long blades, each 7MW turbine will be able to power a UK home for over a day with each single rotation.

Part of an impressive array dotted over 407 km2 of North Sea more than 100km from the Yorkshire coast, the final turbine completes the 174-strong array of turbines, which make up the world's largest offshore wind farm.

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. 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.

Mr Duncan Clark, Orsted Programme Director for Hornsea 1 said that "The milestone of this last turbine being installed only nine months after the first one was erected is just one small part of this record-breaking project. Hornsea 1 has truly paved the way for the next generation of offshore wind farms.”
