DONG Tables Hornsea Project One Offshore Construction Schedule

DONG Energy is currently undertaking the necessary preparations to begin offshore works on the 1.2GW Hornsea Project One offshore wind farm which are scheduled to start in September.

Pre-installation works include activities such as boulder clearance and the inspection of potential unexploded ordnance (UXO) items.

As of July, 21 confirmed UXO targets are currently planned for removal, DONG said.

Following the completion of the boulder and UXO removal activities, DONG will start preliminary offshore export cable installation works in September.

Scour protection works are planned to start in the fourth quarter of 2017 and are expected to be completed in the fourth quarter of 2018.

Installation of the four offshore substations is scheduled to commence in the second quarter of 2018.

All other offshore works, such as the installation of foundations and inter-array cables, are currently scheduled to commence in early 2018, DONG said.

Once operational in 2020, Hornsea Project One will become the largest offshore wind farm in the world, consisting of up to 174 turbines. The Siemens 7MW turbines will be located 120km off the Yorkshire coast, covering an area of approximately 407km2.
