The Princess Elisabeth Island is being realised off the Belgian coast: the world’s first artificial energy island. The island, located in the North Sea approximately 45 km off the Belgian coast, is a groundbreaking initiative in the energy transition. It will collect and transfer offshore wind energy to the mainland.
The project is being executed by the TM Edison consortium, composed of DEME, Jan De Nul and Elia. Our hydraulic Rental equipment supports the precise positioning of caissons that form the island’s concrete foundation.
Our contribution
This equipment is used to position the caissons, each weighing approximately 22,000 tons and transported 98 km across open water to their designated offshore location. The positioning requires millimetre precision and is conducted under challenging maritime conditions.
Project details
Location: North Sea, approx. 45 km off the Belgian coast
Period: 2024–2026
Partners: TM Edison consortium (DEME, Jan De Nul Group, Elia)
Objective: Create an energy island that collects and transmits offshore wind energy to the mainland
Results
The first two caissons have been successfully positioned, marking a significant milestone in the island’s construction. Our hydraulic rental equipment played a key role in ensuring both precision and operational safety during this complex marine operation.
