Mud Wiper Seal
Mud Wiper Seals 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. They prevent mud from penetrating the void between the internal diameter of the platform leg and the external diameter of the anchor pile.
The mud wiper seal provides a mud barrier when the jacket is set on the seabed and avoids mud rising after pile driving.
Mud wiper seals are designed according to :
- Leg ID
- Pile OD
