Suction piles for Subsea structures foundations

If you’re looking for some significant cost reductions in the fabrication and offshore installation of a subsea structure, founding it with SPT Offshore’s suction piles is the solution.

Benefits of suction piles for Subsea structures foundations

  • Proven technology with numerous suction pile founded structures installed worldwide
  • Very swift and vibration free offshore installation
  • Fabrication costs are reduced significantly, since no pile sleeves, -catchers, -centralizers and mud mats are required
  • No pile drive-, leveling- and grout spread and operation required
  • Leveling of the structure < 0.25 degrees by selective suction
  • Easy decommissioning by reversed installation
  • Engineering and installation by one party, hence SPT Offshore takes over installation and in-situ responsibility

Product Characteristics

  • Integrated suction pile foundation of 3 or 4 suction piles in the subsea structure
  • Suction pump is mounted on top of the subsea structure with one hose to each individual suction pile
  • Manifold in the suction pump controls the flow to each suction pile proportionally
  • Subsea structure installations to a maximum of 3,000m water depth
