Race Bank Offshore Wind Farm

For the complex cable installation project between the Race Bank wind farm and the mainland – the nature reserve The Wash on the English east coast – Jan De Nul Group deployed some of their innovative assets.

Two export cables had to bridge a 71 km distance and another 6 km interconnector between both high voltage stations at sea. The cable-laying vessel Isaac Newton was extremely suitable for the works in the deeper areas. However, the last 8 km of the cable route ran through the tidal area of the nature reserve. Therefore, Jan De Nul Group imagined, designed and built two uniquely impressive trenching machines, the Sunfish and the Moonfish. With a minimal ground pressure, they still have enough traction and ran on biodegradable oil as an extra precaution in the environmentally sensitive area. As a result, Jan De Nul Group could meet the most stringent environmental requirements and the cables were placed to depth, to client Ørsted’s total satisfaction.

The cables provide not less than 500,000 households with green power. In total, Jan De Nul Group installed 148 km export cable, meeting the strictest requirements and deadlines. Once again, proof of Jan De Nul Group’s innovative power.
