The deadline for submitting requests to participate in the tender is set for 3 April, with the construction work expected to take two years.

The installation of the caissons will resume this spring, alongside continued works to prepare the island’s interior, according to Jan De Nul , which recently completed construction of the remaining concrete structures for the Princess Elisabeth Energy Island at the Vlissingen site in the Netherlands.
Located 45 kilometres off the Belgian coast, the artificial island will serve as a key connection point for transporting at least 2.1 GW of offshore wind energy generated in the Princess Elisabeth Zone to the mainland.
