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...

Upscaling the TetraSpar: Large-scale floating offshore wind turbines design methodology and modelling

During the past decade, the offshore wind energy industry evolved to bigger turbines, going into deeper waters and farther offshore. As bottom-fixed wind turbines are limited to shallow water depths, floating wind structures are the next frontier to unlock the vast potential of wind energy. Despite many techno-economic challenges, several full...
