Cause of Danish wind vessel collision revealed

Collision

A ‘lack of situational awareness’ caused a wind turbine blade-carrying vessel to collide with another vessel in the Port of Esbjerg last month, Fred. Olsen Windcarrier’s parent company Bonheur has revealed.

The incident involved the Brave Tern, a wind turbine installation vessel owned by Fred. Olsen Windcarrier.

On 10 June, Brave Tern was transporting what appeared to be nine blades for Siemens Gamesa’s flagship 14MW turbines from the Port of Esbjerg in Denmark.

These blades were destined for the 1.1GW Thor offshore wind farm, which German power giant RWE is developing in Danish waters.

As the vessel manoeuvred to exit the harbour, the blades crashed into the Wind Keeper, a vessel operated by Denmark’s Cadeler. That led to Brave Tern colliding with infrastructure on the quay side, further wrecking the blades.
