Ship adrift near TenneT platforms

Downloads & Contact

On Monday 31 January, a cargo ship was cast adrift by storm Corrie in the area where TenneT is building two transformer platforms (Hollandse Kust Zuid Alpha and Beta) for the connection of the wind farm Hollandse Kust Zuid that is being built by Vattenfall. TenneT is currently working on the Hollandse Kust Zuid Alpha platform. Fortunately, the situation was safe for the 100 or so employees present and there was no need to evacuate.

Later on Monday afternoon, the adrift cargo ship collided with the Beta jacket (the foundation of the platform). No people were working here at the moment. As soon as the weather conditions allow, the situation at the jacket can be examined more closely.

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.

TenneT will send a team to inspect the Beta jacket for any damage as soon as possible. Pictures will be taken from a ship. On the basis of this visual inspection, it can be determined whether further investigation by experts on the jacket itself can be safely performed. The visible and non-visible damage above and below water level must be fully assessed to determine whether, and if so what repairs are necessary.

At this moment we can therefore not make any statements about possible damage or the consequences for the delivery of the transformer platform Hollandse Kust Zuid Beta. We expect to need approximately two weeks to analyse the damage and make a plan for any necessary repairs.
