... qualification test that includes a wave basin model test. The numerical simulations can be verified and validated by the wave basin model test results. Certain behaviour or phenomena, which may not be able to be simulated by the software, can also be observed by the wave basin model tests. The whole concept...

... Verifying the robustness of an innovative mooring system poses significant challenges, particularly when design modifications are made after model tests. While initial physical model tests demonstrated feasibility and provided valuable design insights, subsequent changes necessitated...

To introduce wind in the model tests for the application of offshore wind, the present approach is to induce wind loads on the rotor hub through real-time coupling of physical and numerical simulation, also known...

... and subsequently, of the axial load re-gain due to pipe movements, have been made in a suite of centrifuge physical model tests (in O'Beirne et al., 2022a , b ). An analytical tool has been developed to capture these effects and is presented here. More specifically, the model describes the evolution, in a cycle...
