The jacket foundation is becoming more popular as an offshore turbine foundation. Installing these jackets requires a lot of precision and binds contractors to strict installation tolerances. That is why we at TWD have introduced the innovative retrievable jacket pile gripper. It can easily be retrieved and reused for future jacket installations.
A jacket installation consists of multiple phases. First, pre-piles are driven into the seabed. Once the pre-piles are in place, the jacket piles are positioned into the pre-piles. Finally, the voids between the pre-piles and jacket piles are filled up with grout to secure the jacket to the pre-piles. When the grout is curing, the relative motions between the jacket leg and pin pile must be maintained within strict limits. Our retrievable jacket pile gripper makes this process efficient and cost-effective thanks to its reusability.
