Wind Turbine Generator (WTG) foundations

Wind Turbine Generator (WTG) foundations

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
