Heerema Marine Contractors has completed the installation of both offshore substations for Ørsted’s Hornsea Two project. Following the installation of the RCS and OSS jacket foundations in October 2020, the company has now also completed the installation of the topsides. 

Both the offshore substation (OSS) and reactive compensation station (RCS) topsides were delivered to Europe from Singapore onboard Guangzhou Salvage’s 30,000 DWT semi submersible vessel Hua Hai Long.

Heerema’s Sleipnir traveled to the OSS location on October 18 and installed the 8000 metric ton OSS topside. After that, the vessel moved to the shallow water RCS location and installed the 2000 metric ton RCS topside. The job also concludes Heerema’s three-year partnership with Ørsted and their fabricator Sembcorp Marine Offshore Platforms.

Hornsea Two offshore wind farm is located approximately 89 km (55.3 miles) off the Yorkshire coast in the North Sea and adjacent to Hornsea One, the world’s largest offshore wind farm. Hornsea Two will span an offshore area of 462 square kilometres.

At 1.4 GW, Hornsea Two will overtake Hornsea One as the world’s biggest offshore wind farm. The project will use 165 Siemens Gamesa 8MW SG 8.0-167 DD turbines which will deliver 20 percent more annual output than those used for Hornsea One. Ørsted aims to have the Hornsea Two project up and running in 2022.
