Jan De Nul successfully installed two export cables of 70km across England’s most important natural habitats and linked the two offshore substations with an interconnector of 6km.

Race Bank, to be built almost 17mi off Norfolk, and will consist of 91, 6 MW wind turbines.

To execute the nearshore works across the saltmarsh in the Wash, Jan De Nul Group developed and built the award-winning low ground pressure cable installation and burial tools Sunfish and Moonfish. Both machines were deployed from Jan De Nul’s cable installation barge DN120. Offshore cable installation vessel Isaac Newton played a key role in the cable installation and jointing works as well as in the cable burial works with onboard trencher UTV1200 across the shallow Docking Shoals.

“Race Bank has challenging seabed conditions along the offshore export route and the cable installation was identified as one of the key risks to project success.  Jan De Nul rose to the challenge applying their considerable engineering capability to the problems, especially in the nearshore,” says David Summers senior project director for DONG Energy.

The company was awarded the work in March 2016.

In May, electricity was generated for the first time at Race Bank, following the installation of the initial turbines.
