Piling Arrangement

Piles and conductors for 30+ platforms: 150 conductors driven, piles up to 2,134 mm in diameter driven to 80 m

We install jacket piles and drive conductors for offshore platforms: drivability analysis, hammer selection, offshore transportation of piles, driving, jetting where required, welding of add-ons, position control and diving survey.

References: 32 piles of 2,134 and 1,830 mm in diameter with 85 mm wall, driven to 46–76 m for an ice-resistant platform and a living quarters platform; nine 762 mm conductors driven to 80 m; 17 piles weighing 2,796 t in total for the Grayfer ice-resistant platform.

Works are performed from a company-managed transportation and installation barge to procedures approved by an independent Marine Warranty Surveyor; driving is monitored by dynamic measurements.

Scope of work:

  • Piles driving and welding procedures development;
  • Execution of calculations for piles strength and stability during driving;
  • Drivability assessment and appropriate hammer models selection;
  • Project management;
  • Piles and conductors driving;
  • Piles extension using welding;
  • Piles hydro-swaging.

CNGS Engineering services also include provision of equipment (hammers, hydraulic grips, jackets’ levelling equipment, upending frames, followers) and a team of highly qualified specialists with many years of experience successfully performing the above mentioned works.
