BACKGROUND ON THE CONSTRUCTION OF THE OSHORO MARU
The training ship“Oshoro Maru IV” of Hokkaido University, School of Fisheries Sciences, which was built by Mitsui Engineering and Shipbuilding Co.,Ltd. in 1983, has contributed to the seamanship education and development of fisheries sciences in our country, Japan, for the last 31 years. During this period, the ocean environment and fisheries have changed significantly.
Construction of “Oshoro Maru V”, as the replacement ship of the “Oshoro Maru IV”, which is expected to cope with this change, was planned and conducted with the aim of supporting the needs of the field of fisheries sciences for the future by development of human resources who can play vital roles in the field worldwide, conservation of the ocean ecosystem, and management and securing of the seafood resources.
（Completed : July 28, 2014）
FUNCTIONS AND FEATURES
The purposes for building the training ship Oshoro-maru V are to work on training and research regarding the fisheries sciences; to nurture human resources who can play an important role in this science field; to use for interchange of personnel and international collaborative research with domestic and foreign universities and research organizations; and to contribute to the reconstruction efforts of the fisheries industry that was devastated by the 2011 Tohoku earthquake and tsunami.
For these purposes of use, the ship has been designed and constructed as “an ideal fishery training ship” that will be active for a long time and provide an environment for practice of world standard research and education. The ship is also designed to succeed the high seaworthiness of the predecessor, Oshoro-maru IV, which had high sea-keeping and maneuvering performance, and furthermore, to have more sophisticated comfortability and ability for research and training considering the environmental load reduction.
