Swedish energy developer Vattenfall stared disaster in the face over the weekend when an oil tanker was dramatically diverted from a collision course with one of its North Sea wind farms after suffering an engine failure during a storm.

Loaded with fuel oil, the 145-meter-long Eva Schulte vessel was drifting toward the Hollandse Kust Zuid wind farm with waves reaching five meters and storm-force winds in the Dutch North Sea.

A failed anchoring attempt left the vessel just one kilometre from the wind turbines, with its crew members still on board, according to a LinkedIn post by strategic communication advisor at Vattenfall, Martin ter Braak.

“The situation was tense,” ter Braak posted. “Thanks to the swift and courageous response of the (Netherlands Coastguard and the Royal Netherlands Sea Rescue Institution), a towing connection was successfully established around 23h15, stabilising the vessel and preventing a potential disaster.”

He described the incident as is a stark reminder of the growing complexity and risks on the North Sea.

"With increasing maritime traffic, expanding offshore infrastructure, and more frequent extreme weather events, the margin for error is shrinking," according to ter Braak.

Repeated dramas

The 1.5GW Hollandse Kust Zuid wind farm has had more than its fair share of maritime drama.

Earlier this year an 11MW Siemens Gamesa offshore wind turbine was taken offline after damage sustained by a collision incident involving the Glomar Venture offshore supply vessel, reportedly leaving two crewmen injured.

The wind farm suffered a major incident in January 2022.

In that case, the bulk carrier Julietta D ran adrift during a major storm, narrowly missed a gas platform, rammed another vessel and then hit a wind turbine foundation on Hollandse Kust Zuid.

On that occasion the 18-man crew was taken to safety by the Dutch rescue services.
