Major construction milestone for world's largest wind farm

A major milestone has been reached on what will become the world’s largest offshore wind farm, with the export cable system installed on Hornsea One months ahead of schedule.
Featuring 467km of cable, enough to stretch from London to Newcastle, as well as a further onshore lay of 38km to connect to the national grid at the North Killingholme onshore substation, it is the longest of its type ever to be installed.
When fully operational in 2020, it will have the capacity to deliver back enough electricity for more than one million homes, from 174 turbines via three offshore substations, through a reactive compensation station, then to shore.
Duncan Clark, programme director for Hornsea One and Two, said: “This record-breaking project is a step up in scale from the offshore wind farms we have today. It will be the first offshore wind farm in the world with a capacity over 1GW, and at 120km out to sea, we are pioneering new technology and really at the forefront of scaling up clean energy infrastructure with each phase we complete.
“I’d personally like to thank our team including all of the contractors who have enabled us to reach this milestone ahead of schedule. Over 35 vessels were involved in delivering the installation, which was conducted safely and efficiently by all. An incredible feat of logistical coordination, and truly a landmark achievement for both the project and the growing offshore wind industry across the globe.”
Termination and testing is also being completed ahead of schedule, and is expected to conclude within the first months of the new year.
Well over 100 of the 174 foundations have now been installed, and turbine installation is expected to start in the new year too, with Hull's Siemens Gamesa factory manufacturing the blades and pre-assembly and load-out work of the turbines also taking place at Green Port.
Operations and maintenance will take place from Grimsby, with the first Round Three farm a game-changer in numbers, with the East Coast Hub the base for hundreds of Orsted employees and contractors.
