General Substations Windfarms

The first of two offshore substations for the SeaMade offshore wind farm has been in the Belgian North Sea after leaving the construction yard in Hoboken earlier this week.
The 1,200 tonne substation has four decks, is 14 metres high and has an output capacity of 235 MW. It was installed using Scaldis Salvage & Marine Contractors' heavy lift vessel Gulliver at the Mermaid concession.

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 platforms will transform 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).

The SeaMade project comprises two wind farms, Mermaid and Seastar, and is located in Belgian waters approximately 40-50 km off the coast of Ostend, Belgium, in water depths ranging between 22 metres and 38 metres. The project is being developed by project company SeaMade NV, a joint venture of the Otary group (70%), Electrabel (Engie) (17.5%), and Eneco Wind Belgium (12.5%).

The two projects will have a combined capacity of 487 MW and will consist of 58 Siemens Gamesa SG 8.0-167 DD turbines, each with an individual installed capacity of 8.4 MW mounted on monopile foundations. The wind turbines each have a hub height of 109 m and a rotor diameter of 167 m and are expected to power around 500,000 households annually. Once constructed and operational, it is expected to offset 700,000 t of CO2 emissions a year.

Installation of the project's monopile foundations was completed last month by marine contractor DEME Group, using its jack-up installation vessel DP2 Innovation.
