The behaviour of a chemical tanker in extreme waves is discussed in detail by analyzing the experimental data from model tests, in terms of the rigid body heave and pitch motions, vertical bending moments amidships, green water and slamming impacts. Regular wave tests that were conducted for two wave steepness, show that the increase of wave steepness causes increasing asymmetry between hogging and sagging moments and that the green water on deck can contribute to a decrease of vertical wave bending moment. Random uncertainty analysis for statical values in irregular wave tests with different seeds shows quite small experimental uncertainties on motions and vertical bending moments and slightly higher errors in slamming pressure peaks. With a higher forward speed, experimental uncertainty on slamming pressures at the bow increases. The good performance of breather solutions of the nonlinear Schrödinger equation applied to generate tailored extreme waves of certain critical wavelengths in terms of ship response is further verified for the chemical tanker.
