On Monday 31 January, due to storm Corrie a cargo ship was cast adrift in the area where TenneT is building two transformer platforms (Hollandse Kust Zuid Alpha and Beta) for the offshore grid connection of the wind farm Hollandse Kust Zuid, that is being built by Vattenfall.

The adrift cargo ship collided with the Beta jacket (the foundation of the platform). No people were working there at the time. 

During the design and construction of our jackets, scenarios are made for a ship of limited size to collide with the jacket. Further investigation will determine the impact of this collision.

What we can see now is that the jacket has been dented and the cable deck (bordes) damaged at one corner. TenneT will now inspect the damage to the jacket, both above and under water level. We expect to have a clear picture of the exact damage to the jacket by early March, so that we can make a plan for the necessary repairs.
