Our role in the construction of the Princess Elisabeth Energy Island (MOG2 Project), located off the coast of Belgium, has reached its final phase. Just before Christmas, the last caisson (23rd) was moved to the floating dock using our skidding system.
Since 20 March 2024, caisson production has been underway in Vlissingen, the Netherlands. These caissons form the foundation of the artificial island, which is designed to consolidate and distribute offshore wind energy.
We supplied the serial production system, consisting of a heavy-duty slipform and skidding system (IP-CCV units), enabling the base slab to be moved to the slipform station and the completed caisson to be positioned on the floating dock for launch at sea.






The Princess Elisabeth Energy Island, located 45 km off the Belgian coast, will become a central hub for offshore wind power in the North Sea, collecting electricity from wind farms and transmitting it via hybrid interconnectors to the UK and Denmark.
Built from concrete caissons placed on the seabed and protected by a high perimeter wall, the island is designed to withstand extreme marine conditions. The project is technically demanding and requires detailed maritime planning, but it will play a crucial role in Belgium’s future electricity supply.
More than infrastructure, the project is a clear symbol of the European energy transition.
We thank TM Edison, Jan De Nul and DEME for the strong partnership and look forward to continued collaboration.
