Outline of Final Research Achievements

This study aims to evaluate the hydrodynamic performance of pusher and barge system (PB) which is unique and different from other commercial vessels and has been rarely discussed comprehensively. The resistance characteristic and maneuverability of PB were investigated by towing tank test, maneuvering simulation and CFD analysis. Especially the effect of barge loading condition on the maneuverability was interesting and the mechanism behind deterioration of the course stability in full loading condition was revealed. The resistance performance tried to be improved as well by developing the barge stern shape with focus on the wake field shed from the barge. In addition, the applicability of PB into Mahakam River in Indonesia which has been famous for coal transport by towing barge was discussed. The result of ship handling simulation indicates the navigation safety in such a serpentine and congested river would be improved by putting PB into service.
