Outline of Final Research Achievements

In this study, onboard measuring of ship performances has been implemented for six years to know the slow down patterns in rough seas. Here, following parameters are focused to analyze the voluntary speed loss, such as the vertical acceleration, roll angle, probabilities of deck wetness and slamming, etc. Furthermore, various parameters are also being monitored in the engine room. This point is researched on the nationwide questionnaire for shipping companies, and measured parameters related on main engine. New parameters to evaluate the voluntary speed loss are summarized.
