Two substations for the SeaMade offshore wind farm have been successfully installed by DEME in the Belgian North Sea.
Each with a weight of 1 200 t, the substations transform the wind energy that is produced to 225 kV, which in turn allows the electricity to be brought to shore via Elia’s Modular Offshore Grid (MOG). The export cable transmitting the electricity to shore has been installed earlier with DEME’s cable installation vessel ‘Living Stone’.
The installation of the substations was executed with heavy lift vessel ‘Gulliver’, operated by DEME’s subsidiary Scaldis which is specialised in marine heavy lifting works. Earlier DEME’s offshore installation vessel ‘Innovation’ installed all of the foundations, including those for the two substations.
The installation of 58 turbines will begin in Spring. DEME will deploy its offshore installation vessel ‘Apollo’, which recently performed the precision foundation piling operation at the Moray East offshore wind farm in Scotland. However, this will be the first turbine installation project for ‘Apollo’. This versatile vessel has had a full orderbook since its inauguration in February 2019.
In April 2020, cable installation vessel ‘Living Stone’ will start the installation of the inter array cables.
