First turbine spins at SeaMade

In: Windfarms
The first turbine is spinning at the SeaMade offshore wind farm in the Belgian North Sea. With a 487 MW capacity, SeaMade is the largest offshore wind farm in Belgium.

Offshore construction of the SeaMade wind farm started in September 2019, with the last foundation installed in January 2020, followed by connection via subsea cables.

DEME’s DP2 offshore installation vessel
Apollo is installing the 58 Siemens Gamesa 8.4 MW turbines on the monopile foundations. It is loading wind turbine components from the Renewable Energy Base Ostend (REBO), which is used as the marshalling harbour for the project. From Ostend, Apollo transports the tower elements, nacelles and blades, with a total weight of 1,000 tons each, for installation at the SeaMade site which is about 45 km off the Belgian coast.

The vessel features an 800 ton, leg-encircling crane and an unobstructed 2,000 m² deck with a load carrying capacity of 15 t/m².

The SeaMade project is made up of two wind farms,
Mermaid and Seastar, and is located in Belgian waters approximately 40-50 km off the coast of Ostend, in water depths between 22 and 38 metres. The project is being developed by 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. Each wind turbine has a hub height of 109 metres and a rotor diameter of 167 metres, and they are expected to power around 500,000 households annually. Once constructed and operational, the project is expected to offset 700,000 tons of CO2 emissions a year.
