A novel experimental campaign for an articulated VLFS is carried out to test the performance of the platform subject to irregular sea states. Rigid and hinged connectors are utilised to analyse performance. Different numerical methods are implemented to compare their accuracy. Two potential flow solvers, namely the discrete-module-beam (DMB) method and the open source potential flow solver SEA-Stack Hydrochrono. And a CFD Openfoam framework specifically developed for articulated VLFS. We compare
