Experimental investigations were conducted on a steel catenary riser (SCR) with different stiffness seafloor models both in dry and wet conditions. The motion oscillator and cell load connect the riser model in a tank, and forced motions with different amplitudes and frequencies were studied. Model tests are conducted in air and a small scale factor (1/435) is used. This model has been built having as reference a riser prototype in 900 m water depth and the numerical analysis is carried out in time domain using the developed CABLE3D. Results demonstrate the influence of the platform in-plane motion on the dynamic response of the riser model, and both of them are consistently good. This study provides a novel and simple experimental tool developed for testing of the SCR global dynamic analysis, and discusses the results including motion response, top tension and dynamic curvature near touchdown zone.
