BOA Offshore has completed its caisson launching scope for Princess Elisabeth Energy Island, described as the world’s first artificial energy island, located 45 km off the Belgian coast in the North Sea.
The campaign covered the launch of 23 concrete caissons, each weighing up to 22,400 tonnes. The work was carried out with the semi-submersible BOABARGE 33, which was modified for extreme stern load-out operations.
With dimensions of 140 × 57.05 × 8.54 m and 5,800 m² of deck space, BOABARGE 33 was equipped for the controlled launch of the large structures. The vessel can submerge to 21.5 m above deck, supporting safe execution during the campaign.
Alongside the barge scope, BOA Offshore also delivered project engineering and operational management for the works. The company said these services supported safe and efficient execution across the full campaign.
The completed scope closes BOA Offshore’s involvement in the Princess Elisabeth Energy Island campaign. According to the company, the project is one of Europe’s most ambitious renewable energy infrastructure developments. The island will connect offshore wind capacity from the Princess Elisabeth Zone and support the future offshore electricity grid in the North Sea.
