First cable to connect wind farms at sea Borssele reaches coast

Downloads & Contact

TenneT has laid the first sea cable to connect the Alpha platform to the transformer substation in Borssele. In the morning of Friday 12 April, Boskalis started withdrawing the sea cable on land and early Saturday morning the cable reached the newly built transformer substation.

The cable-laying vessel, Giant 7, then repositioned itself in the Honte and started with the most critical part of the installation: crossing the fairway. Before crossing the channel, shipping traffic to and from the port of Antwerp was blocked until Sunday afternoon. The crossing went completely according to plan and the traffic got back on track in the course of the evening.
In the coming weeks, preparations will be made to also connect the second sea cable for the Borssele Alpha project to the transformer station.
