As the US offshore wind sector scrambles to develop a supply chain equal to the task of building out a gigascale fleet off its coasts, a top executive at Danish turbine maker Vestas has warned that the even greater concern will be “keeping factories filled” for the decades ahead as the sector takes shape.

Vestas’ biggest apprehension looking ahead, said Josh Irwin, senior vice president for the OEM’s offshore business unit in America,“is not how do we get the factory started, but how are we going to keep it full year after year without boom and bust”.
