Vattenfall has cancelled and will redo tenders for foundations, transition pieces, array cables and turbine installation for its 350MW Vesterhav project in the Danish North Sea.
The Swedish developer has also requested a three-year extension of the near-shore project’s commissioning deadline to 2023.
The moves come after Vattenfall was forced by the Danish Energy Agency to prepare a supplementary environmental impact assessment for both the project’s northern and southern sectors.
The company has already selected Siemens Gamesa to supply 41 8.0-167 DD turbines to the project.
A Vattenfall spokesman confirmed that when it came to the turbine related contracts, only the installation tender had been cancelled and not the supply deal with Siemens Gamesa.
The company estimated that the new EIA process would take around 1.5 years to complete.
“We believe that our project is in line with the original environmental impact assessment,” head of offshore wind Michael Simmelsgaard said.
“Nevertheless, we have to factor in the possibility that the supplementary assessment will result in one or more turbines being moved.”
“We have therefore requested that the deadline for commissioning of the project is moved to 2023.”
Simmelsgaard said the circumstances under which Vattenfall tendered some of the main components had changed substantially, so it could no longer keep those tenders open.
“We regret having to cancel this process, but greatly appreciate the participation and understanding of all suppliers,” he said.
“These elements will have to be re-tendered at a later stage.”
