    <p>Automatic collision avoidance is of significant importance to prevent maritime collisions. Although many studies have been conducted in recent years, autonomous system has not completely replaced human captains since it is still difficult to imitate their complicated decisions. Thus, the present paper tries to investigate and imitate experienced captains' maneuver using maximum entropy inverse reinforcement learning (MaxEnt IRL). We firstly verify that MaxEnt IRL can reproduce appropriate reward function from demonstrative trajectories. Afterwards, we conduct an experiment on a simulator where well-experienced captains maneuver in congested sea and estimate reward from the trajectories. Searching the route which maximizes the obtained reward, finally, we demonstrate the optimized route can avoid collision against multiple ships in compliance with the International Regulations for Preventing Collisions at Sea (COLREGs).</p>

    Surf-riding/broaching is a dangerous event for high-speed ships running in stern quartering seas. Theoretical methods for the prediction of wave-induced forces on ships in surf-riding and broaching situations are still of the qualitative level. Therefore, an unsteady Reynolds-averaged Navier–Stokes computational fluid dynamics (CFD) solver with overset grids was applied to predict the wave-induced forces on ships in irregular stern quartering seas. To validate the CFD method, a dedicated model experiment was conducted for slender ships, and the wave-induced forces were measured to be for a direct comparison with CFD predictions using the same irregular waves encountered. The comparison results indicate good agreement between the CFD results and the experimental fluid dynamics (EFD) results except for the wave-induced roll moment.

    For providing a benchmark data for numerical codes for parametric roll prediction, a model experiment of a post-Panamax C11 class containership whose hull form is slightly modified from its original but opened for public was conducted and significant parametric rolling in irregular head waves was recorded. A 3DOF (degrees of freedom) numerical model based on the nonlinear strip theory is developed. The numerical code for time domain simulations is developed for the prediction of large amplitude of parametric roll both in regular and irregular head waves. Comparisons between the model experiment and the numerical simulations show good agreement under the consideration of dispersion due to practical non-ergodicity. By utilizing the developed numerical model, it was demonstrated that small height of the bilge keels is a major reason why significant parametric roll could happen for a C11 class post-Panamax containership in 1998.

    In this study, the characteristics of rolling in head waves for a vessel with strong nonlinear GZ-curve, which includes parametric rolling, are investigated. Rolling is measured for systematically changed wave length and height under the same forward speed, which is service speed in heavy weather. As a result, the range of Te/Tϕ (Te and Tϕ are encounter wave period and the roll natural period of the model) when oscillatory rolling occurs is wider than that of previous results by Taguchi et al. (Model Experiment on Parametric Rolling of a Post-Panamax Containership in Head Waves. Proceedings of the Ninth International Conference on Stability of Ships and Ocean Vehicles, 2006), and the range spreads out wide area of Te/Tϕ > 0.5. Especially, in the range of Te/Tϕ > 0.5, oscillatory rolling is caused by large wave height and roll amplitude becomes larger than that at Te/T = 0.5. It is supposed that the result is caused by change of roll natural period caused by nonlinear GZ-curve. In order to confirm it, numerical simulations are carried out for several variations of GZ-curve. Additionally, roll measurements in irregular waves with Pierson-Moskowitz spectrum are also carried out.
