Semco Maritime

Semco Maritime delivered a full electrical engineering, procurement, construction and installation (EPCI) package for the offshore substation serving the Princess Amalia (Prinses Amaliawindpark) offshore wind farm in the Dutch part of the North Sea. The work was executed during 2006–2007 and related to the build and offshore installation of the wind farm’s substation topside, which had a reported topside weight of about 650 tonnes and supported the project’s 120 MW capacity. Semco Maritime’s scope covered multiple electrical and auxiliary systems disciplines required for an operational offshore high-voltage station. The referenced systems included low-voltage systems, cableways and cable pulling, HVAC, firefighting and fire detection systems, communication systems, and diesel power generation, together with overall project management. The substation enabled aggregation and export of power from the 60-turbine wind farm to the onshore grid. The customer for Semco Maritime’s contract was CS WIND (previously known as Bladt Industries), with Eneco identified as the end customer. The case reference states the project was performed on time and received positive feedback from the customer, indicating successful delivery and installation coordination for one of the Netherlands’ early offshore wind farm substations.
