In the port of Zeebrugge Jan De Nul NV, branch of Jan De Nul Group, is constructing 16 concrete wind turbine foundations by order of the Swedish client Eon.
The foundations were built on 2 pontoons in the inner harbour of Zeebrugge in 4 phases: concrete slab, retaining walls, central shaft and icecone. The height of these elements ranges from 15 to 25 m. The heaviest element weighs approximately 1,940 tons. What makes this project so unique is that the large and heavy foundation elements are constructed on pontoons and in a very short period of only 5 months.
The biggest pontoon departed the port successfully yesterday at 6 p.m.
The design, the construction, as well as the installation at sea are executed by Jan De Nul Group.
