Trelleborg’s engineered products operation has added to its portfolio of offshore floatover solutions with a custom designed skirt pile gripper (SPG).
Trelleborg’s SPGs can be designed to have a holding capacity of between 500MT and 3000MT and are compatible with all offshore oil and gas and wind farm HVDC jackets. The DNV GL-certified units can work at operating pressures of 200 bar and higher, and water depths of up to 250 meters.
The SPG is welded onto the upper section of a platform’s jacket skirt pile sleeves and is designed to create a temporary connection between the pile and jacket during the grouting process.
“Jacket installation of a substructure into the seabed is an operation that requires product reliability and on site expertise. Until the grout between pile and jacket has set and the installation is completed, the SPGs holds the jacket’s piles firmly in place to provide temporary retention of the jacket’s elevation position during levelling operations and grout setting,” JP Chia , Engineering Manager for Trelleborg’s engineered products operation, said.
With the addition of the skirt pile gripper to the existing grout seal, diaphragm closure and grout packer products, the company is now able to offer a total sub-structure leg can system.
