Vibro Lifting Tool Drives 6.5m Monopile
CAPE Holland has recently achieved another milestone with its Vibro Lifting Tool (VLT) on the Maasvlakte 2 in Rotterdam. A large, 6.5m diameter monopile was successfully upended and driven to target penetration.
Free hanging from the Matador 3 of Bonn and Mees the VLT only needed a net driving time of 15 mins to get the 330t weighing monopile to a penetration depth of 24m. Without any other tool, gripper or installation frame the pile ended up at 0.05° verticality which was well within the set tolerance. For this project, CAPE Holland used a Tandem configuration of the CV-320 VLT-U with a total of 640kgm.
The VLT proved an ideal tool to drive the test pile of Fistuca to sufficient depth to place the 700t weighing Blue Piling Hammer on top ready for the inshore testing program.
