Jacket skirt pile installation, CA-Ku project Mexico (2019)


Offshore Mexico the SINGLE CV-320-VLT-U installed a total of 9 piles with a length of more than 100m and diameters of 60 and 64 inch. The piles had to be installed through the skirts of 2 tripods in a water depth of 60m. With various types of clay the self-weight penetration of the piles didn’t allow for a conventional installation lifting the piles simply into place and disconnect from the crane as calculations were indicating pile instability. With the Vibro-Lifting-Tool this was solved and the tool was even able to install 8 out of the 9 piles to final penetration, eliminating a tool-change and reducing the installation time.
