Self Installing Platform Type 2 (SIP-2)

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.

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

Benefits of the SIP-2

  • 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
