HSM Offshore Energy THOR OHVS detail

Published on 25 April 2023

HSM Offshore Energy, located in Schiedam, The Netherlands is awarded the engineering, procurement, construction, installation and commissioning of the offshore high voltage substation and its jacket foundation.

RWE will build the Thor wind farm off the Danish west coast – approximately 22 kilometres from Thorsminde on the west coast of Jutland. The wind farm will consist of 72 wind turbine generators (WTG’s).

HSM Offshore Energy together with its key subcontractors Iv-Offshore & Energy for engineering and GE Renewable Energy for the MV/ HV package are responsible for the engineering, construction, installation and offshore commissioning of the less than 3000mt Topside and 2500mt Jacket structures.

HSM Offshore Energy THOR OHVS


Based on our experience and technical know-how we created a highly efficient design for RWE’s Thor OHVS substation and jacket. This reduces the use of structural steel and the energy needed during manufacturing – with steel sourcing and fabrication in Europe.

Thor will be Denmark’s largest offshore wind farm to date. Thor would be capable of producing enough green electricity to supply the equivalent of more than one million Danish households.
