A dynamic lift analysis has been performed for a new Pile Gripper. This system has been designed for heavy monopiles weighing more than 2000 ton.
The objective of this analysis is to determine the operational limits of the system.
The gripper frame is mounted on deck of the company owned jack-up installation vessel. The frame will guide the monopole during installation/piling, while hanging in the crane.
Orca offshore has modelled various stages of the pile installation to determine the effect of gripper stiffness, pile size and pile position on the workability of the system.
The system has been modelled in MOSES as a multibody dynamic model to derive the motions and internal loads of the pile, the crane block, the crane and the gripper system.
