5FUNCTIONS AND UNIQUE FEATURESHull design for safety and rational use: The minimised superstructure and enlarged main hull provide an extensive deck area and good sea-keeping quality. The buttock-ow hull with a bulbous bow reduces hydrodynamic resistance and saves energy.Unique manoeuvrability: A combination of azimuth propulsion and bow-thruster with a joystick control system enables motions such as holding a position, turning around a point and diagonal transfer. The manoeuvrability strengthened particularly at low speed increases opportunities of surveys and experiments and, consequently, enables fruitful education and researches.Electric propulsion system: Four main generators and two electric motors enable installation of an azimuth propulsion system and reduce vibration and noise in the hull, which results in comfortable accommodation areas. Low-level noise scattering into water enables tranquil hydro-acoustic surveys and experiments with less inuence to the organisms. Discharge of pollutants such as nitrogen oxide (NOx) and sulphur oxide (SOx) is reduced.All-round view bridge: The spacious bridge with all-round view serves as a navigation bridge and a control centre for sheries, oceanographic and other practices. In order to accommodate an increased number of students, a large bridge with sucient space was designed.Multi-purpose shing system: A variety of shing gear such as bottom and mid-layer trawls, surface seine and longline are systemised, while allowing monitoring their underwater behaviour. Consequently, education and researches on shing technology for the next generation is possible.Oceanographic and resource survey system: A CTD unit and other oceanographic survey equipment, such as a tension-controlled winch and a crane with disconnecting device have been installed around the centre of ship’s motion. A combination of this arrangement and her unique manoeuvrability enables safe and rational oceanographic surveys, while minimising the inuence of the ship’s motion.Mobile platform for education and research: The CTD hanger, dry and wet laboratories and extensive through deck starboard are integrally arranged considering trac lines. This ensures a safe and ecient training environment. A new concept of a mobile platform for education and research as surveys continue throughout cruising is materialised by a continuous biological sampling system.Education for traceability: High performance liquid chromatography (HPLC) and a traceability recording/analysis system permit education on seafood quality management from harvesting through to marketing (laboratory practices).Advanced information network: Integrated management of data obtained from navigation, shing operations and biological and oceanographic surveys by an advanced information network provides a system which enables sharing of data aboard and allows the utilisation of the accumulated data for subsequent education activities.Comfortable and safe living environment: Wide bilge keels along the streamline aside the hull enhance the anti-rolling character. This assures the safety of students particularly from other universities which do not provide basic on-board training and introduces a comfortable work environment, breaking a stereotype of unstable work conditions on board.Acceptability for diverse users: Bilingual signs aboard and manuals and sanitation facilities for female have been improved. Consequently, diverse users such as foreigners and female students/researchers are encouraged and the vessel contributes to realisation of a gender-equal society and international use.Reduction of running cost: Reduction of running cost was intended by piping and lining designed for easy maintenance, power management utilising the electric propulsion and equipment for maintenance for the engineering section.
