NMRI Researchers Received the Best Paper Awards and the Best Paper Award for the Youth (Inui Award) from the Japan Society of Naval Architects and Ocean Engineers
♦Best Paper Award
4 researchers, Mrs. Sakurada, Dr. Kuroda, Dr. Tsujimoto and Mr. Sogihara, developed a new correction method on ship displacement to ensure the accuracy of the estimation of fuel consumption in actual seas over a wide range of the displacement of ±20%, which is important as the analysis of ship monitoring data. The research was conducted in collaborate research with MOL Co., Ltd. The content of the new method was evaluated. Mr. Matsui and Osaka University carried out a collapse analysis of a container ship under longitudinal bending moment using FEM and clarified the collapse mechanism. After extracting the dominant factors for ultimate strength, they developed the “extended Smith’s method” considering local bending deformation of double bottom due to bottom local loads, and furthermore, expressed the effect of local bending deformation on ultimate strength in an explicit formula, which were evaluated.

♦Best Paper Award for the Youth (Inui Award)
Chief Researcher Mr.Yuzui developed a new cost-effectiveness assessment method in the IMO-based Regulation Formulation Method FSA (Formal Safety Assessment). Using this method, he conducted a FSA on the Review of Required Zone Index R, which is the Rule of Stability at Damage of Passenger Vessels, and evaluated the content of the method. Conventional FSA used to evaluate the cost-effectiveness for individual vessels, but we developed a method to evaluate the cost-effectiveness for an entire fleet, which is subject to the revision of the regulations. Inui Award awards young researchers who presented original and excellent papers to encourage the creative research of young researchers in marine engineering and ocean engineering and to encourage the development of a wide range of technologies.
