The upscaling of floating wind turbines and the lightweight design of floating support structures make floater flexibility increasingly important for the dynamic response and load transfer of two-body floating platforms. This study investigates the influence of upper-floater flexibility on Tsemi, a previously proposed suspended-ballast two-body floating platform supporting the IEA 22 MW reference wind turbine, using a fully co...

The intensification of climate changes has led to increased tropical cyclone (TC) intensities and subsequent damage, emphasizing the critical need for accurate trajectory prediction to mitigate their impact. In this study, a graph-theory-based approach was employed for the identification of TC trajectory. Using reanalysis data, each targeted TC can be constructed as a graph during its TC lifetime. Four graph metrics are comput...

In order to study the scale effect in wave-structure interactions and the role that structure-related parameters (tension T or bending stiffness EI ) plays, riser model tests under regular waves were conducted using the model with multiple geometric scales (1:15, 1:12 and 1:9) in a wave basin. The riser model used is a novel structural design combing the outer polyvinyl chloride pipe with the core steel rod which could be simp...
