... Abstract Wind loads represent an important contribution to the design loads of large floating offshore structures during installation, normal operation and in extreme conditions. It impacts the intact stability of the floating structure as well as its mooring loads. In many cases the wind loads...

... Abstract This paper suggests the improved technology to predict the wind and current loads on offshore structures such as FPSO and Semi-submersible. Wind tunnel tests and CFD analysis are conducted and results and application methods are discussed. The characteristics of flow and extrapolation...
