Suction Pile Jacket

If you’re looking for significant cost reductions in offshore jacket installation our suction piles are the solution.

Benefits of suction piles for jacket foundations

  • Proven technology with numerous suction pile founded jackets installed worldwide
  • Very 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
  • Easy decommissioning by reversed installation
  • Engineering and installation by one party, hence SPT Offshore may take over installation and in-situ responsibility
  • Integrated scour protection system, hence no seabed preparations or rock dumping

Product Characteristics

  • Water depth up to 60 meter

Tri-suction Pile Caisson (TSPC)

If you’re looking for low cost and eco-friendly suction pile foundations for offshore wind turbines, the TSPC is the solution.

Benefits of the TSPC

  • Reduced offshore lifting capacity 
  • Innovative combination of proven technology results in low risks and high predictability
  • Economical fabrication
  • Very swift offshore installation
  • Noise-free and vibration-free installation
  • Removal and decommissioning by reverse installation – Fast and without a trace

Product Characteristics

  • Combining cost efficient monopile technology with the superior foundation performance of a suction piles.
  • 30% cost saving compared to piled jackets
  • Wind turbines from 15MW
  • Water depths up to 60m
  • Suited for wide range of soils from:
    – loose to dense sands
    – soft to stiff clays
    – layered soils
    – sediments over rock
