Benefits of suction piles for jacket foundations

  • Proven technology with numerous suction pile founded platforms installed worldwide
  • Very swift offshore installation a couple of hours for suction operation compared to several days pile driving
  • Fabrication costs are reduced significantly, since no pile sleeves, -catchers, -centralizers, mud mats and leveling padeyes are required
  • No pile drive-, leveling- and grout spread and operation required
  • Noise free installation
  • Easy decommissioning by reversed installation
  • If buoyancy tanks are applied, no heavy lift vessel is required for installation
  • Platform can be relocated, spreading CAPEX
  • Engineering and installation by one party, hence SPT Offshore takes over installation and in-situ responsibility
  • Integrated scour protection system, hence no seabed preparations or rock dumping
