BOA has announced that it has been awarded a contract by TM Edison, a joint venture between Jan De Nul and DEME, for the launching of 23 concrete caissons for the world’s first energy Island, Princess Elisabeth Island, located in the Belgian part of the North Sea.

For the launching of these caissons with weights up to 22.400 t, BOA will provide the semi-submersible
Boa Barge 33 (140 x 57,05 x 8.54), modified to manage load-outs of extreme weights over the stern. The Boa Barge 33 has capacities of submerging up to 21, 5 m of water above deck, uniform deck strength of 31.5 t/m2 and a free deck are 5,800 m2 and can accommodate the load-out and float-off of heavy loads.

BOAs scope of work also includes project engineering and operational management. The operations are aimed to commence during spring 2024.

The Princess Elisabeth Island will be the world’s first artificial energy island that combines both direct current (HVDC) and alternating current (HVAC). The island’s high-voltage infrastructure will bundle the wind farm export cables of the Princess Elisabeth zone together, whilst also serving as a hub for future interconnectors with Great Britain (Nautilus) and Denmark (TritonLink). These are so-called ‘hybrid interconnectors’ that facilitate the exchange of electricity between countries and are also connected with offshore wind farms in the North Sea that will in due course provide energy.
