4 TAPERED PIN PILES FOR JACKET FOUNDATION

In 2017, the CAPE VLT-320 was used to upend and install four pin piles with a 84 inch bottom and 60 inch top diameter and a length of 77 meters in a waterdepth of 85 meters for a jacket foundation for the ZOHR WHP in Egyptian waters.

By driving the piles to a stable depth, any risk of the template falling over as there is with the traditional installation method is mitigated.

This way, even in places with low self-penetration, all piles can be placed in position without tool changes, before the impact hammer is deployed once, to drive all piles to final penetration in a single lift.
