With steelwork fabrication about to start, designers for the world’s largest offshore wind farm are scrambling to redesign the first 175 turbine foundations. A generic foundation fault at several European wind farms is the latest squall the U.K.’s 1,000-MW London Array must navigate.
“We have been asked to change the design,” says Jasper Jacobsen, project director at ABJV, the development’s construction joint venture. The team includes Denmark’s Per Aarsleff A/S, Aabyhoej, and Bilfinger Berger A.G., Mannheim, Germany. “It's a challenge, but it can be done,” he says.
