Pre-piling - Culzean, North Sea

20-07-2015

In 2015, during its first commercial application, the newly developed Vibro Lifting Tool (VLT) of CAPE Holland has successfully installed 4 piles in up to 90m water depth. This installation was part of the pre-piling project for the Culzean Wellhead Platform jacket which will be installed in 2016. The VLT was used as a stabbing tool to install all 4 piles in one sequence to stable depth through a template without any tool change. Negating the need for a tool change meant it was possible to install all 4 piles in just one 12 hour shift to the predicted penetration depths, which resulted in a significant time saving.

Reason for equipment choice

  • No separate upending lifting tool required 
  • Low self-penentration risking unstable pile in template
  • Reduction of subsea lifts
  • Subsea capabilities

 

The CV-320 VLT-U set includes:

  • CV-320 VLT with Upending option
  • 2x PU-1180 in Offshore skid
  • Cable Reel
  • Hose Reel
  • Master Control Cabin
