At the end of November, the ‘steel cutting’ ceremony for the Offshore High Voltage Station (OHVS) for RWE’s Thor Offshore Wind Farm took place at the HSM Offshore Energy (HSM) yard in Schiedam, the Netherlands.
Both the jacket foundation and the topside for the OHVS-station for RWE will be built here. HSM Offshore Energy, together with its key subcontractors Iv-Offshore & Energy and GE Renewable Energy, was awared the engineering, procurement, construction, installation and commissioning of the topside and jacket in 2022.
The selection was based on HSM Offshore Energy’s experience and technical know-how to create a highly efficient design. The open design of the substation, which will have a capacity of more than 1,000 megawatts (MW) and overall weight below 3000MT is a gamechanger in the offshore wind market, offering best AC power / weight ratio in the history, HSM says. This reduces the use of structural steel and the energy needed during manufacturing – with steel sourcing and fabrication in Europe.
THOR Offshore Wind Farm
RWE will build the Thor wind farm off the Danish west coast – approximately 22 km from Thorsminde on the west coast of Jutland. To connect the wind farm to the Danish grid, RWE will build two new substations – one at sea and one on land. The substation at sea is the nerve centre of the wind farm: the electricity produced by the individual wind turbines is collected here and transformed to transmission-level voltage. The green electricity will be transported through export cables to the new-build onshore substation Thor will be Denmark’s largest offshore wind farm to date and will be capable of producing enough green electricity to supply the equivalent of more than one million Danish households.
