GROUTING NEW SKIRT PILE GRIPPER
Trelleborg’s engineered products operation is growing its portfolio of offshore floatover solutions, with a custom designed skirt pile gripper
Add to this its grout seal, diaphragm closure and grout packer products and customers can now specify a total sub-structure leg can system from one source.
to create a temporary connection between the pile and jacket during the grouting process. With unique biting teeth for increased contact area, Trelleborg’s innovative design delivers a firmer grip. This fixing method reduces risks during platform installation, as it guarantees stable working conditions, even in inclement weather.
PRODUCT RELIABILITY JP Chia, Engineering Manager for Trelleborg’s engineered products operation, commented: “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.
UNIQUE DESIGN
The skirt pile gripper (SPG) is welded onto the upper section of a platform’s jacket skirt pile sleeves and is designed
“By growing our portfolio to offer a total leg can system solution, customers can benefit from streamlined procurement,
reliable functionality and interfacing of the entire system from purchase through to delivery from one solution provider.”
HOLDING CAPACITY
The custom-made SPGs can be designed to have a holding capacity of between 500MT and 3000MT and are compatible with all offshore oil & gas and windfarm HVDC jackets. Working at operating pressures of 200 bar and higher according to customer testing requirements, and water depths of up to 250 metres, the SPGs exceed all relevant client standards and is DNV GL certified.
DEVELOPMENT AND TESTING The SPGs are fully developed and tested in-house at the company’s facility in Singapore. Full scale testing, biting teeth friction testing and pressure holding testing are all carried out and exceed client specified standards to ensure they perform during the critical grouting process.
