    Ship Design Subarea

    Professor UMEDA Naoya   Associate Professor MAKI Atsuo
    This subarea investigates ship safety at sea. For preventing sea disasters which could result in marine pollution and/or loss of many human lives, ship manoeuvrability and stability are focused in the light of free-running model experiments, nonlinear dynamics, automatic control theories, random process theory and so on. The research results could contribute to development of manoeuvring standards against collisions, stability criteria against capsizing, and minimum propulsion power requirements against grounding in adverse weather conditions, which could upgrade future ship designs.

    Ship Structural Integrity Subarea

    Professor FUJIKUBO Masahiko   Associate Professor IIJIMA Kazuhiro   Assistant Professor TATSUMI Akira
    This subarea deals with a wide range of research topics related to strength of ships and offshore structures. The research topics include 'hydro-elastoplasticity problem of ship', 'Interaction between global (hullgirder) and local (e.g. double bottom) strength', 'behavior of structures for harnesing renewable energy under combned wind and wave loads', 'single-point-moored floating structure', 'strength analysis of deep-sea risers and drill pipes', 'aquacultural net', 'VLFS', etc. The staffs and students amounting to about 25 in number are yielding new research findings every day.

    Hull Form Design Subarea

    Professor TODA Yasuyuki   Associate Professor MATSUMURA Kiyoshige   Assistant Professor WU Ping-Chen
    The flow field and hydrodynamic forces around ships and under water vehicle are investigated using the theoretical, experimental and computational fluid dynamics to understand the relationship between the hull or vehicle form and the performance. Many ship related projects such as optimum hull form design, low drag body design and new propulsor development are carried out.

    Ocean Material Engineering Subarea

    Professor OSAWA Naoki   Associate Professor HAYASHI Shigehiro   Assistant Professor SAWAMURA Junji
    We pursue education and research on material and related technologies for asset integrity management of ships and offshore structures (fatigue and corrosion), design of ships and offshore structures in ice sea (maneuverability and structural response under ice load), fabrication technologies of large steel structures (curved plate forming, straightening). Also studied is applied mechanics theory such as non self-adjoint problems.

    Ocean Space Development Subarea

    Professor KASHIWAGI Masashi   Associate Professor MINOURA Munehiko
    With wave-body interactions set as the core theme, research on the propulsion and seakeeping performance of ships in actual seas is conducted in terms of theoretical analyses, numerical computations, and wave-basin experiments. Contribution to the university-industry collaboration is made in the development of “an analysis system for ship propulsion performance in waves” by integrating analysis tools developed so far. In addition, in conjunction with the use of ocean energy and space, we are also doing research on hydroelastic performance of a very large floating structure, wave-energy absorption, and development of a platform to be used for offshore wind-energy utilization.

    Marine Mechanical System Engineering Subarea

    Professor HASEGAWA Kazuhiko   Associate Professor SUZUKI Hiroyoshi   Assistant Professor SENGA Hidetaka
    We are conducting advanced education and research aiming at not only development of marine machines and new those functions preserving marine environment, but also disaster prevention of large scale industrial parks damaged by large scale natural hazards, based on the subjects of marine hydrodynamics, vehicle dynamics and robotics, combined with oceanology, biomechanics and disaster prevention engineering.
