This paper presents the hydrodynamic coefficients obtained from forced oscillation tests of a C11 type container vessel and their comparison to strip theory. Heave and pitch added mass and damping values are investigated through scaled model testing. Three inclination angles are considered: upright, 5 degrees, and 10 degrees. Forced oscillation tests carried out on this heeled vessel with asymmetric cross-sections aim to understand how they deviate from their upright position counterparts and if strip theory is able to capture this change. The experimental setup considers two speeds, allowing the evaluation of speed effects. In addition to the speeds and inclination angles, the forced oscillation survey includes three amplitudes of motion in each heave and pitch modes to assess nonlinearities in six periods of oscillation.
