Assessment and analysis of hook mounted compensation methods for offshore wind turbine blade installation

During single-blade offshore wind turbine (OWT) installation, wind disturbance results in blade root motion. The sensitivity to this wind disturbance is more significant for larger blades, reducing the allowable installation weather limit. A potential solution is a Hook Mounted Compensator (HMC) between the crane and the load that can provide...

QUAD Lift Workability Analysis: Evaluating the Dynamic Interaction Between Two Dual crane Vessels using a Frequency Domain Modelling Technique

A QUAD lift is a new lifting method in which dual crane vessels combine their vessel capability to increase their offshore lift performance. The use of the Jumbo J-Class vessels in a QUAD lift creates the opportunity to increase the offshore lift capacity and to install structures with larger dimensions. When floating vessels are close to each...
