Dredging International, GeoSea and Tideway – subsidiaries of Belgian company Dredging, Environmental and Marine Engineering (DEME), have won contracts worth €500m for the 487MW SeaMade Offshore Wind Farm in Belgium.
The project reached financial close on 3 December 2018.
SeaMade consists of a combination of two offshore wind projects in Belgium, previously known as Mermaid (235MW) and Seastar (252MW).
The project, comprising 58 wind turbines, will be located 40-50km off the coast from Ostend.
The contracts are for Foundations, turbines and inter-array cables, Substations and Export cables.
Dredging International will carry out the EPCI contract for the 58 foundations and the inter-array cables. The cables will connect each turbine to the relevant offshore substation.
The monopile foundation will have a hub height of 109m and a rotor diameter of 167m. The wind turbines will be the largest to be installed so far in the Belgian North Sea.
The Mermaid and Seastar wind farms will have their own offshore substations, which will collect electricity produced, convert it from 33kV to 220kV and export it into the grid.
GeoSea, ENGIE and Smulders will work on the SeaMade project and this partnership will be responsible for the full engineering, procurement, construction, transport, installation and commissioning of the two high-voltage substations.
Two 220kV submarine high-voltage cables will connect the two wind farms to the Belgian Modular Offshore Grid.
Tideway, in a consortium with Hellenic Cables, will be responsible for the design, manufacturing and installation operations, and for connecting the wind farms high-voltage substations to the Belgian Modular Offshore Grid.
The export cables will have a combined length of approximately 28km.
Construction has already been initiated and offshore works are expected to start in 2019. Both wind farms are expected to be operational before the end of 2020.
DEME director and CEO Alain Bernard said: “We will deploy our specialised high-tech equipment, know-how and local experience to efficiently and safely carry out the SeaMade project, as well as export this valuable experience in many projects in Europe and beyond.
“After the successful cooperation for the Rentel project we will again use the REBO site in the port of Ostend as our base for wind turbine assembly, transport and installation.”
