Construction has begun at Hornsea Project One, the world’s biggest offshore wind farm being developed by Orsted, off the coast of England.
According to Orsted, 174 monopiles have been installed at the site, located 120km off the Yorkshire coast.
The wind farm is expected to be operational in 2020 and produce enough power for more than one million homes.
GeoSea’s installation vessel, Innovation, is carrying out the installation. The vessel carries up to four monopiles at a time. Each monopole is 65m long, weighs around 800 tonnes and has a diameter of 8.1m.
The vessel will also be used to install some of the transition pieces for the project. A2Sea’s vessel, Sea Installer, will join Innovation in March to continue with transition piece installation.
Programme director for the project Duncan Clark said: “After years of planning, it is fantastic to see the initial stages of offshore construction begin. My thanks to the teams working day and night on this significant milestone.
“Onshore, we are continuing to construct the East Coast Hub, which will serve as an operations and maintenance base for our existing wind farms in the area and both Hornsea Project One, and Project Two which we took a final investment decision on last year.
“These wind farms will not only greatly contribute to the UK’s goal of decarbonising our energy system, they are also bringing jobs and investment to Grimsby and the North East.”
Orsted, which was formerly known as DONG Energy, is an offshore wind farm developer. The company has two operational wind farms off the east coast: Westermost Rough and Lincs.
Race Bank Wind Farm, which is nearing the end of construction, will be opened later in 2018 and Hornsea Projects One and Two will then be taken up.
The combined projects will generate enough clean electricity for over 2.3 million UK homes.
