    <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>

  • Mechanism of Inclination of Spar-Buoy with Ring-Fin Motion Stabilizer in Shallow Sea Caused by Tidal Currents and Waves and Avoidance of the Inclination

    Yamamoto Yusuke, Katayama Toru, Morimoto Taishi, Taniguchi Tomoki, Hashimoto Hirotada, Goto Masahiro

    Journal of the Japan Society of Naval Architects and Ocean Engineers   33   231 - 246   2021( ISSN:1880-3717

     More details

    <p>The main topics of this paper are the motion characteristics of a spar-buoy. Motion measurements for the spar-buoy with and without a ring-fin motion stabilizer in currents and waves were carried out at the circular water channel and the towing tank of Osaka Prefecture University, to investigate the characteristics of its motion. Motion amplitude of the spar-buoy with the stabilizer is much smaller than the spar-buoy without the stabilizer, however, the spar-buoy with the stabilizer causes the inclination that means a time average value of motion and the inclination becomes larger according to increase in wave height. On the other hand, from the results in currents, the inclination of the spar-buoy with the stabilizer is much smaller than the results of the spar-buoy without the stabilizer, however, it is found that there is clear possibility that it has multi-balanced-inclinations for higher current velocity than the designed current velocity. The mechanisms of these unexpected phenomena were investigated, and it is indicated that they can be avoided to optimize cross-section shape of the stabilizer to change its characteristics of hydrodynamics.</p>

    Free-running model tests were conducted using a scaled model of a large cruise ship with a damaged compartment, to investigate the effects of damage opening and floodwater on the manoeuvring performance in calm water and regular and irregular head waves. Drifting tests in regular beam waves were also performed. The experimental results indicated that the course-keeping ability in waves and turning ability became worse in the damaged condition. However, the target ship retained its manoeuvrability for safe return to the port, on its own, even in a damaged state. As it is time- and cost-consuming to conduct a free-running model experiment, a captive model test was also carried out to develop a system-based simulation model for evaluating the manoeuvrability of large cruise ships after damage.

    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.

    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.

  • Prediction of Parametric Rolling in Irregular Head Waves, Contemporary Ideas on Ship Stability -Risk of Capsizing- Reviewed

    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.
