Hornsea Two wind farm construction commences offshore

Construction of Ørsted’s Hornsea Two offshore wind farm has hit a major milestone after the first significant piece of infrastructure was installed.

Six weeks ago, 10,000 tonnes of steel framework for the development’s pin piles, reactor compensation and offshore substation jackets set sail from Batam in Indonesia bound for the North Sea.

The first 4,800 tonne jacket has now been lifted and installed in to its final position for the site’s offshore substation.

Hornsea Two will be located around 89 kilometres off the Yorkshire coast, adjacent to the Hornsea One development which is already under construction.

The 165-turbine project, which will be the biggest in the world upon completion, will have an installed capacity of 1.4 gigawatts, enough to power 1.3 million homes in the UK.

On Monday, the Danish renewables giant confirmed that work to install monopiles and transition pieces would get underway in the coming weeks.

Patrick Harnett, Ørsted senior programme director for Hornsea Two said: ”We’re delighted to announce that we’ve now officially commenced our offshore construction for Hornsea Two with the installation of our offshore substation and reactor compensation jackets.

“Through a remarkable feat of engineering together with our partners, we’ve overcome COVID challenges and are on track for fabricating the world’s largest AC offshore substation, which will be supported by this gigantic steel structure. The ambition and capability of our teams across the world has been remarkable as we continue to overcome obstacles with safe and efficient solutions.”
