Ørsted has celebrated a construction milestone as the first turbine for Hornsea Two offshore wind farm is installed at the site.

Located 89 km off the Yorkshire coast, Ørsted’s
Hornsea Two project will surpass its predecessor, Hornsea One, and become the world's largest offshore wind farm once complete in 2022. Covering an area larger than four times the size of Manchester, it will consist of 165 Siemens Gamesa 8 MW SG 8.0-167 DD turbines and be able to generate 1.4 GW of energy.

Each turbine will stand 200 metres above sea level, with a swept diameter of 167 metres. One turbine alone will provide enough energy for 160,000 hour-long video conferences.

The first load of turbines left the port of Hull earlier this week via the installation vessel
Sea Challenger, owned by DEME Offshore. Equipped with components for four individual turbines, including the new 81 metre-long blades which have been manufactured at Siemens Gamesa Renewable Energy’s blade factory in Hull.

Patrick Harnett, Senior Programme Director for Hornsea Two at Ørsted, said: “I am incredibly proud of the way our teams have worked collaboratively during this difficult time to ensure that our plans for installation were able to go ahead as planned.

“Hornsea Two will be the world’s largest and offshore wind farm and is already paving the way for future renewable energy projects which will have a significant impact on our mission to reach Net Zero.”

After a recruitment campaign last year saw more than 1,200 people apply for positions as wind turbine technicians, the site is also gearing up to welcome their accommodation which will come in the form of a new service operations vessel (SOV). Wind of Hope, which was built in Turkey on behalf of vessel owners Louis Dreyfus Armateurs, is expected to arrive at the port in Grimsby over the coming months.
