During foundation works at the Triton Knoll offshore wind farm an accident occurred involving the Seaway Strashnov which left five people injured.  

According to 4C Offshore's source, the accident was the result of the transition piece lifting gear aboard the
Seaway Strashnov not being fully detached from one of the foundations. As the vessel was moving away, the transition piece subsequently heeled and collided with the vessel while there was people on the foundation platform.

4C contacted Seaway 7, operators of the
Seaway Strashnov , who issued the following statement: "Seaway 7 can confirm that five people have been injured following an incident on board Seaway Strashnov, a heavy lift vessel conducting operations on the Triton Knoll offshore windfarm which is located 20 miles off the coast of Lincolnshire, UK.

"All five were transferred to hospital onshore for further assessment and medical treatment following the incident, which happened at approximately midnight on Friday, May 8. Three of the injured were discharged on Saturday, 9 May, with two persons recovering in hospital. The remaining crew are safe on board and returned to port on Sunday, May 10.

"At the time, we mobilised our emergency response teams, who were able to monitor and respond to the situation.

"Our priority is to ensure the safety and wellbeing of all individuals involved.

"We are working with the relevant authorities and all other involved parties to enable a comprehensive investigation into the cause of the incident. We would like to thank the emergency services for their support throughout the incident."


Located 32 km off the coast of Lincolnshire in the east of England,
Triton Knoll is owned by innogy (59%), J-Power (25%), and Kansai Electric Power (16%) with innogy managing the construction as well as long-term operation and maintenance works, on behalf of its project partners.

A spokesperson from Triton Knoll commented: "An investigation is being carried out into the cause of an accident which happened overnight on Friday 8 May, involving five people who were working on the Seaway Strashnov for Triton Knoll Offshore Wind Farm.


"At the time, all five were airlifted to hospital for assessment and treatment. Three were discharged the next day and a fourth a few days later, while one person remains recovering in hospital.


"The Strashnov and its crew have returned to port while the investigation is underway. Our priority remains the safety and wellbeing of all those involved, and to support the investigation team and the implementation of their findings."


The vessel is currently berthed in Rotterdam. Both parties declined to provide any information regarding damage to the vessel or the foundation at
Triton Knoll.

Foundation installation at
Triton Knoll started in January 2020. Each foundation consists of a steel monopile which weighs on average 600 tonnes and measures around 54 metres long as well as a transition piece.

The wind farm will feature 90
V164-9.5 MW turbines mounted on monopile foundations connected by over 100 km of cabling. It is expected to produce first power in 2021. Once fully operational, it will be capable of generating enough renewable energy to power the equivalent of over 800,000 typical UK households.
