Mammoet Van Oord's Jumping Jack

Mammoet Van Oord's jack-up barge "Jumping Jack" in the River Yare at Gorleston / Great Yarmouth.

 

Jumping Jack was used to insert the piles for the Scroby Sands wind farm. Each of the 30 wind turbines at Scroby Sands has a monopile (single pile) foundation. The 200ft long cylindrical steel tubes are 4m in diameter and up to 50m long. The piles were installed by Mammoet Van Oord. The 'Jumping Jack' installation vessel hammered the piles about 30m into the sea bed using a hydraulic ram.
