A model of an oil production floater is experimentally tested in regular and irregular waves for both fixed and free-moving structure. Measurements mainly concern the rigid body motions and the free surface elevation at 24 locations: 6 inside a moon-pool and 18 along the walls and above an immersed pontoon. Two natural periods of oscillation are experimentally identified inside the moon-pool and compared to linear diffraction and radiation computation and analytical formulas. Outside the moon-pool the wave run-up can be significant and strongly nonlinear, some modal periods are identified and compared to simplified formulation.
