1st SeaMade Offshore Substation Hits Water

The first of two offshore substations for the 487MW SeaMade offshore wind project – Belgium’s largest - has left the construction yard in Hoboken for its final destination in the Belgian North Sea.

The 1,200 tonne substation has four decks, is 14 meters high and has an output capacity of 235MW.

SeaMade originates from the merger of two offshore wind projects, previously known as Mermaid (235 MW) and Seastar (252 MW). The SeaMade wind turbines are expected to produce green energy as from mid-2020 onwards, contributing to the Belgian climate targets and the country’s future energy supply.

After a successful collaboration on previous offshore wind farm projects, ENGIE Fabricom, Tractebel, Smulders and DEME Offshore joined forces for the full EPCI scope (engineering, procurement, construction, transport, installation and commissioning) of SeaMade’s high voltage substations.

The partners have a strong track record in offering integrated solutions to the global offshore wind industry.

The high voltage substation is the beating heart of the offshore wind farm. It transforms the wind energy that is produced to 225 kV, which in turn allows the electricity to transfer to shore via Elia’s Modular Offshore Grid (MOG).

Mathias Verkest, CEO SeaMade Offshore Wind Farm said: “It is really exciting to witness the load-out of this massive 1,200 tonne steel construction at the Fabricom assembly yard. We are happy that the first out of two offshore substations is heading to the Mermaid concession area and are grateful for the tremendous hours of work spent by the combined teams to bring this to a success. Thanks to a close collaboration and the enormous commitment of a dedicated team and our contractors, we will be able to deliver green energy to 485,000 Belgian households.”

Raf Iemants, Managing Director of Smulders said: “We’re very pleased that we could participate in the construction of the new Belgian offshore windfarms Mermaid and Seastar. The substations will join the already installed substations foundations and the 58 WTG foundations, which were also supplied by Smulders. Next step is the offshore installation of the Mermaid OSS and its commissioning to enable it to provide green power to Belgian households.”

Philippe Van Troeye, CEO of ENGIE Benelux: “ENGIE’s participation in the SeaMade offshore wind farm strengthens both our position as the country’s largest green energy producer and our ambition to lead the zero carbon transition. We are proud to be involved in SeaMade on several levels. On the one hand, ENGIE has always been a partner of this important renewable energy project in Belgium, and the combined expertise of our subsidiaries ENGIE Fabricom and Tractebel have contributed to the successful construction of the high-voltage substations on the other hand.”
