Construction work has started on what will be the world’s largest offshore wind farm.
Ørsted says construction work on the world’s largest offshore wind farm has started.
The Danish firm announced that the first of 174 monopiles has been installed at the site of the Hornsea Project One wind farm, located 120 km off the coast of Yorkshire, northern England.
“After years of planning it is fantastic to see the initial stages of offshore construction begin,” said Duncan Clark, programme director for the project. “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.”
The installation is being carried out by GeoSea’s installation vessel, Innovation. It will carry up to four monopiles at a time, each one is 65 m long, weighs around 800 t and has a diameter of 8.1 m.
The Innovation vessel will then also be used to install some of the transition pieces for the project, and in March will be joined by A2Sea’s vessel Sea Installer to continue with transition piece installation.
Hornsea Project One is expected to start operating in 2020 and will have an installed capacity of 1200 MW. It will use Siemens Gamesa SWT-7.0-154 wind turbines.
Hornsea Project Two will have an installed capacity of 1.3 GW.
