Requirements for characteristics of a large oceanographic research vessel are extended over various fields of its design by general-purpose of running work such as getting various kinds of fundamental data about the ocean, researching works on board of the vessel by many researchers and running itself over world-wide reached polar region. And recent developments of acoustic measurements and its instruments such as multi-narrow beam etc. also require noise abatement for its design because of both of air borne and water borne noise caused by the vessel itself. Under the above circumstances, the design features and achievements of research and developments of such vessels are shown especially as general arrangement, type of power plant, hull form, maneuvering, sea keeping, noise abatement by the choice of propellers, mounting of machineries and structure, and also design and building schedule in the example case of "HAKUHO-MARU", the newest and most sophisticated research vessel for the Ocean Research Institute, the University of Tokyo, built by MHI's Shimonoseki Shipyard and Machinery Works, 1989.
