Grout Packer

Once an offshore oil and gas jacket or HVDC jacket substructure is completed, it is transported to the offshore installation site, where it is upended and positioned onto the seabed. To ensure a secure and stable installation, a pile is driven through the jacket leg or skirt sleeves, and the annular space between the pile and the jacket is sealed using inflatable grout packers. These packers, when inflated with gas or liquid, create a tight seal to prevent any leakage during the grouting process, providing a strong bond that keeps the jacket firmly anchored.

Trelleborg’s jacket leg can system is expertly designed to address the specific sealing needs of oil and gas or HVDC jacket substructures. Our Grout Packers (GP), constructed from reinforced rubber, undergo rigorous quality control, including pressure testing and weld inspections, to ensure reliability and performance.

Available in various sizes to meet individual project specifications, our packers ensure precise sealing and effective slurry grout solidification. Additionally, GPs can be equipped with our Grout Seal (GS) to safeguard the grouting process from contaminants, further enhancing the substructure’s integrity and stability.
