Jackets with suction pile foundations

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

Benefits of suction piles for jacket foundations

  • Proven technology with numerous suction pile founded platforms installed worldwide
  • Swift offshore installation a couple of hours for suction operation
  • 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, no noise mitigation required
  • Easy decommissioning by reversed installation
  • If buoyancy tanks are applied, no heavy lift vessel is required for installation
  • When engineering and installation by SPT Offshore, we take over installation and in-situ responsibility
  • Integrated scour protection system, hence no seabed preparations or rock dumping

Product Characteristics

  • Traditional jacket with integrated suction pile foundation
  • Water depths up to 120 meter

Platform Type 1 (SIP1)

If you’re looking for a fast-track and cost efficient platform which can be quickly installed offshore, SIP-1 is the answer. This type of platform is especially designed for minimum facilites and marginal fields and are transported and installed in one piece. If heavier topsides are required, the topsides can be lifted on the tripod substructure seperatly.

Benefits of the SIP1

  • Proven proprietary technology with 4 successful SIP-1 installations
  • Total offshore installation in less than 16 hours
  • Platform can easily be relocated, spreading CAPEX
  • 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
  • Cold commissioning can be per formed onshore
  • Engineering and installation by one party, hence SPT Offshore takes over installation and in-situ responsibility
  • If buoyancy tanks are applied, no heavy lift vessel is required for installation

Product Characteristics

  • Tripod platform founded by suction piles
  • Topsides weight up to 1,000mT
  • Water depth up to 100m
  • Up to 6 conductors protected in the main column

Platform Type 2 (SIP2)

If you’re looking for a fast-track, cost efficient and easily relocatable platform which can be quickly installed without the use of a heavy lift vessel, SIP-2 is the answer. This type of platform is especially designed for marginal fields, with an expected field lifetime less than 10 years.

Benefits of the SIP2

  • Proven proprietary technology with 9 successful SIP-2 installations and 3 relocations
  • Offshore installation in less less than 52 hours
  • Platform can easily be relocated, spreading CAPEX
  • No heavy lift vessel required, improving flexibility and reducing costs
  • 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
  • Cold commissioning can be per formed onshore
  • Engineering and installation by one party, hence SPT Offshore takes over installation and in-situ responsibility

Product Characteristics

  • Four legged platform founded on suction piles
  • Topsides weight up to 15,000t
  • Water depth up to 60m
  • Up to 4 conductors protected in the platform legs
