SPT Offshore - Market leader in the design, fabrication and installation of suction pile foundations

SPT Offshore is a specialised contractor and market leader in the design, fabrication and installation of suction pile foundations and anchors. We applied the suction pile technology for:

  • Oil & gas platforms
  • Wellhead protectors and blow-out preventers
  • Anchors for FPSO's and buoys
  • Offshore wind turbine foundations
  • Substations.

Worldwide we installed over 450 suction piles and anchors since 1997. The technique is feasible in almost all sedimented type of soils.

We installed and relocated 14 pieces off our patented Self-Installing Platforms for small to medium sized platforms up to 10,000 tonnes like the Centrica F3FA platforms. We provide T&I services for our Self-Installing Platforms and lifted installations using sheerlegs for topsides up to 25,000 ton using our innovative technology. Furthermore, we supply and install complete moorings including hook-up to the FPSO, buoy or floating wind turbine.

In 2019 we will execute the decommissioning and relocation of the Ophir wellhead platform to the Jitang field offshore Malaysia. The relocation scope is based on a one-piece lift (topside + jacket). With this innovative relocation method, SPT Offshore is setting the new benchmark for re-usable platforms in a very demanding and environmentally orientated market.

Our staff is specialised in project management as well as geotechnical, structural, project and marine engineering. SPT operates its own suction pump spreads for the installation of suction piles and anchors from shallow (5m) to deep water (3,000m), which are operated by our offshore installation crews. Besides our pumps we have rent out suction piles for temporary start-ups or moorings.

We focus on the research and development of efficient concepts achieving flexibility and cost reductions for its customers.

We have developed an innovative scour protection system around suction piles. The umbrella-like system uses SSCS frond mats, is pre-installed onshore, and is self-deploying during installation of the suction piles.

Together with Cathie Associates and Oxford University we are involved in the development of Design Guidelines for the design of Suction Piles/Buckets as foundations for offshore wind turbines and substations for Carbon Trust. This incorporates the design for installation and capacity as well as subjects directly related to the performance of the foundations, such as scour protection and underbase filling.

Unlike the massive sound generated by the blows of underwater hammers, the installation operation of suction piles is virtually noise-free. Suction pile installation does not cause vibrations in the seabed that may disturb marine species or damage adjacent structures. At the end of its lifetime the suction piles and attached structures can be fully removed by simply reversing the operation.

Allseas Noble Leviathan: Project management and preparation of installation engineering document for two start-up piles. Provison of start-up pile and suction installation services.
Aberdeen Offshore Windfarm: The detailed design and installation of 33 suction pile foundations for the foundation of eleven (11) suction bucket jackets for the Aberdeen Offshore Wind Farm. The jackets support the world's largest 8.4MW Vestas wind turbines.
Ophir Wellhead platform: For the Ophir wellhead platform, SPT Offshore realised the detailed design of the suction pile foundation, the design supervision of the jacket and full transportation and installation (T&I) of the platform.
Wintershall L6-B Minimum Facility Platform: The L6-B platform is a minimum facility platform developed and constructed for Wintershall using the SPT Offshore's proprietary SIP-1 concept. The platform is designed for installation in one piece, which resulted in a mobilisation, installation and demobilisation in only three days. The verticality of the structure is within 0.01 degrees achieved by individual and proportional suction on each of the suction piles.
