Grout Seals

Grout Seals, or lip seals, are cylindrical inflatable jacks that are slipped inside platform legs. Unlike the Grout Packers, these jacks are not inflatable. They have two functions:

  • solidifying the anchor pile inside each platform leg
  • and improving the platform’s anchoring at sea.

Made from high resistance rubber coated fabric with a snap seal and assembled by hot vulcanisation, our grout seals are designed to take into account: 

  • Leg ID 
  • Pile oD 
  • The grout column to a maximum pressure of 1 bar

A steel insert is vulcanized within the grout seal providing perfect tightness to the leg and eliminating the risk of the grout seal separating from the flange. No inflation line is required. 

This is a solution for your oil & gas project. 

Our teams can travel on-site to install your offshore buoyancy kits no matter where you are located !
