Wind Energy – HKW Collaboration
Ecowende and Sif will collaborate on the construction of Ecowende’s offshore wind farm Hollandse Kust West site VI, located about 53 kilometres off the Dutch coast.
The collaboration for this project dates to February 2023 when Sif announced having taken a final investment decision on the expansion of its manufacturing facilities in Rotterdam. At that occasion Ecowende, as a launching client for the expanded factory, committed to participate in its financing through an Advance Factory Payment. T
The project was already in Sif’s order book for 70 kilotonnes but with the signature of the final contract is now firm for production in 2025.
Sif will be responsible for the manufacturing of the 52 extended monopile foundations that will have no transition pieces, but secondary steel components, and that will have a total weight of approximately 70 kilotonnes.
Transition piece-less monopiles were successfully applied by Sif in earlier projects offshore the Netherlands, also in the Hollandse Kust Noord project for Crosswind.
In this transition piece-less design, the secondary steel components like boat-landings, ladders, main access platforms and internal platforms, will be connected to the monopile foundations once these are installed at sea. The secondary steel components will also be delivered by Sif in the same contract.
