Foundation structures for Riffgat from Belgium

G&G International will deliver 30 gigantic foundation structures for offshore wind turbines between May and July 2012. It is the largest order that the engineering and construction company has ever received, as it states.

The foundation structures (monopiles) consist of heavy steel constructions measuring 70 metres long and weighing 650 tonnes that are driven into the seabed at a depth of between 18 and 23 metres. G&G International will also manufacture 30 transition pieces to connect the foundation structures (the monopiles) to the towers. Each transition piece measures 30 metres in height and weighs 250 tonnes. They are complex constructions with several platforms and places for boat landings, electrical and mechanical equipment and access points to the towers. The constructions are sustainably designed and finished to provide at least 23 years of service in the extremely onerous and corrosive North Sea environment. They will be delivered to Vlissingen between May and July 2012 as complete units.
