Clients: Shell, BP and Woodside.

  • Pipeline Walking Restraint
  • Buckle Control
  • Increased Axial Friction
  • Flexibles and Rigids

Subcon’s Pipe Clamping Mattress (PCM) is a step-change technique for pipeline axial restraint. Through transferring 100% of the ballast directly onto the pipeline, the PCM saves up to 80% on materials, logistics and installation time compared with rock dumping and standard concrete mattresses. It is highly competitive against suction pile anchors, removing the need for costly heavy-lift T&I vessels.

PCMs are the most efficient system in the market for increasing pipeline axial friction and can be used for multiple pipeline stabilisation requirements in addition to walking mitigation.
