A member of the crew of Swire Blue Ocean jack-up Pacific Osprey, who was seriously injured when a section of a crane boom collapsed on Thursday, has been discharged from intensive care.

The vessel operator said three other crew members suffered only "minor injuries" and are no longer in hospital. A fifth individual has been treated for shock.

"Next of kin have been notified and have travelled to the location where the company is providing all necessary support," added Swire in an updated statment.

The incident occurred when the vessel (pictured) was jacked-up and undergoing crane maintenance while berthed at Eemshaven, the Netherlands.

Swire said all those injured “received prompt medical attention”. 

“The crane was undergoing maintenance at the time of the incident and the vessel has suffered significant damage as a result. There were no injuries to any third party personnel nor any damage to the port infrastructure,” the company said earlier on Friday.

Pacific Osprey had been deployed installing foundations at EnBW’s 497MW Hohe See wind farm in the German North Sea, which it had been due to complete shortly.

Swire chief executive Mikkel Gleerup added: “The safety and well-being of our people is always our first priority. All support and resources have been mobilised to assist those affected. We are managing the incident closely and cooperating fully with the local authorities.”
