A dynamic lift analysis has been performed for a pile gripper design by Euro Rigging bv. This system will be used to install monopiles for the Veja Mate offshore wind farm project using the Seajacks Scylla jack-up. The objective of this analysis is to determine the operational limits of the system.
The gripper frame is mounted on deck of the jack-up installation vessel Seajacks Scylla. The frame will guide the monopile, weight 1,350 tons with a length of 90 metres during installation/piling, while hanging in the crane.
Orca offshore has modelled various stages of the of the pile installation to determine the best damping settings to achieve the best 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 and the gripper system.
