Mud Wipers

Mud Wipers are circular lip seals designed to prevent mud rising from the seafloor. Acting as an effective “anti-mud” barrier, they prevent all impurities entering the legs of offshore platforms.

These non-inflatable toric seals are used to prepare grouting operations by preventing mud from penetrating the void between the internal diameter of the platform leg and the external diameter of the anchor pile.

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