Grout packer
Inflatable Grout packers, or inflatable toric seals, are used in operations for concreting the void between the internal diameter of the platform leg and the external diameter of the anchor pile. They are used for:
- Solidifying the anchor pile inside each platform leg
- Improving the platform’s anchoring at sea
The grout packers provide a perfect reliable seal between the ID of the leg and the OD of the pile for grouting purposes. They are the most efficient seals for grouting operations taking into account the grout column and water depth.
Our solutions are made from high resistance rubber coated fabric. In addition, they are assembled by hot vulcanization.
This is a solution for your oil & gas project.
Inflatable packers can withstand a high grout column or water depth independent of the jacket leg dimensions. The grouting operation can be completed in one stage.
Avantages
Reliability
- Allows the trellis to be installed horizontally or vertically
- Resin is not required to fix the lip seal
- Corresponds to a small annular void between the external dimension of the pile and the internal dimension of the pile sleeve.
Safety
- Selection of materials
- Tightness testing can be implemented on request
- Can be inflated by air, water, and nitrogen
Handling
- Single-block
- Seal width can be defined by the clients’ specifications
- Ease of installation
