X1000 Universal Extractor - Case Study
X1000 Universal Pile Extractor Job Example –
Easington, England (2005)
Main contractor Jan De Nul carried out construction works for a gas pipeline landfall at Easington. The offshore pipeline runs for over 1200 km, making it the worlds longest.
The steel piling included several beach cofferdams and two parallel lines running out to sea. All the piles required extraction after the pipe was laid; the longest were AZ36-630 crimped pairs at 24m, driven to refusal with a Dawson HPH 6500 impact hammer.
The X1000 operated for several months, its ability to apply up to 1000t of static pull force ensured it successfully extracted all the required piles, even where a PTC 100HD vibrator (2630kN centrifugal force) failed.
