Ballast Nedam installed the last of twelve monopile foundations on the beach at the outer edge of Maasvlakte 2, Rotterdam. They are part of the Maasvlakte 2 Wind Farm.
The wind farm will feature twenty-two Vestas wind turbines. Twelve of these are placed on the soft sea wall (beach) and ten on concrete foundations on the hard sea wall.
Ballast Nedam was awarded the contract to build the foundations in November 2021. Preparatory construction activities on site started in February. Due to the location, Ballast Nedam implemented a flanged monopile foundation design for the 12 wind turbines. It is the first time that monopile foundations are being used for onshore wind turbines.
The first of the 40 m-high monopile foundations with an average 5 metre diameter was installed on the beach in May this year. The monopiles were produced by Sif. Solidd Steel Structures supplied the secondary steel work. A CAPE VLT was used to upend and drive the piles to a stable depth from a temporary platform on the beach. The piles were driven to final penetration with a S-1400 Hydrohammer. (see video)
Ballast Nedam now continues with the 10 remaining turbines on the hard sea wall.
Maasvlakte 2 Wind Farm is being realised by Eneco on behalf of Rijkswaterstaat, the Ministry of Infrastructure and Water Management. The project is planned to be completed by 2023. The 116,7 MW wind farm will then be generating approximately 416 GWh annually. Photo: Screenshot video Ballast Nedam
