HSM Offshore Energy is a reputable EPCIC Contractor having delivered Offshore HV Substations for more than 20 years with capacity up to 1060 MW.

 The main 75.000 M2 Schiedam yard is situated in the greater Rotterdam Harbour area and features open North Sea access, deep water load out quay and large climate controlled construction and assembly halls for platform topsides and module projects, with a large open space area for the construction of substructures. 

In 2023 a second yard was secured on long term lease basis, situated 20 minutes upstream from the Schiedam yard, almost doubling our annual capacity.

Furthermore a long term MoU was established with GE Grid Solutions, specifically to add High Voltage design, grid compliance studies and provision of critical High Voltage Equipment for our range of HV Offshore Substations.

In addition it has been established to facilitate standardisation and the development of new concepts. 

JV company H2Sea was established in 2022 to facilitate the design and construction of offshore hydrogen production facilities.
