Race Bank offshore wind farm


The Race Bank Offshore wind farm is located approximately 27 kilometres off the coast of North Norfolk in the UK and covers an area of 75 km2, with water depths varying from 12 m to 22 m. 
The wind farm is equipped with 91, 6 MW Siemens turbines and has a total capacity of 580 MW. The wind turbine generator foundations consist of a monopile (MP) and a grouted transition piece (TP). Prior to the foundation installation, scour protection had to be installed at 62 locations. 

Our solution


Ørsted awarded DEME Offshore the contract to install the scour protection, as well as the Transport & Installation of the foundations. The scour protection was also performed by DEME Offshore.
The outer harbour of Great Yarmouth in the UK was chosen as the designated load-out port for the foundations. The MPs were fabricated by Steelwind Nordenham in Germany, and the TPs by Bilfinger in Szczecin, Poland. Both the MPs and TPs were transported from the fabrication yards to the load-out port by DEME Offshore's own transport barges and tugs. 

In Great Yarmouth, the DEME heavy lift jack-up vessel ‘Innovation’ used its own crane to load four sets of foundation components from the barges for each trip, after which she could set sail to the field for the installation operation.
