Once an offshore wind High Voltage Direct Current (HVDC) jacket is constructed, it will be transported to the offshore installation site where it will be upended and descended onto the seabed. In order to ensure that the jacket is securely fixed to the seabed, piles are driven through the jacket legs or the skirt sleeves. The annulus between the pile and the jacket leg or skirt sleeves will be sealed by a grout seal. It seals the annular gap to ensure that no leakage can occur during grouting. The grout will provide a reliable bond to keep the jacket secured and stable. The grout seal helps to keep the grouting process free from contaminants, reinforcing the integrity of the substructure.

Odin GS (Grout Seal) provides reliable and robust sealing between the inner diameter of the jacket or skirt, and the outer diameter of the pile. Odin GS can also be used as a standalone solution.

Odin GS can tolerate reverse movement and offset position in the pile. We can design and supply a total sub-structure leg can system to meet individual project requirements and specifications.

Trelleborg’s Odin jacket leg can system is designed to encompass the sealing needs during the installation of an HVDC jacket substructure.
