Boskalis' subsidiary VBMS in consortium with NKT Cables has been awarded the Borssele Alpha contract by TenneT for the installation of two export cables that will connect the Borssele offshore wind farms 1 and 2 to TenneT's onshore grid in the Netherlands.
The contract value of Boskalis' share is approximately EUR 70 million. Separately, the option has been awarded for the installation of the export cables that will connect the Borssele offshore wind farms 3 and 4 to the Dutch onshore grid (Borssele Beta), subject to financial close.
61 Km Export Cables
The grid connection of the Borssele offshore wind area in the North Sea consists of two 700 MW connections, called Alpha (for Borssele 1 and 2) and Beta (for Borssele 3 and 4). The contract for the Alpha export cabling scope entails the supply and installation of two 61-km-long export cables. The cables will be routed via the Western Skeldt estuary and will come ashore near the existing high-voltage substation at Borssele, the Netherlands.
To minimise maintenance to the cables during their operational lifetime, Boskalis will pre-sweep and dredge the shallow parts of the route, which will enable VBMS to simultaneously lay and bury the export cables at the required depth.
VBMS and NKT Cables plan to carry out the project in 2018 and 2019.
