NKK'S POLAR ICE SIMULATION TANK OPENED AT TSU LABORATORY

A tank which simulates various polar-ice conditions was recently put into full operation at the Tsu Laboratories of NKK <Nippon Kokan KK.>. This is the second such tank in Japan and the first to be built by that country's private sector. It is to be used in basic cryogenic experiments and for studies of machinery and ships necessary for the development of polar resources; ship resistance and self-propulsion tests, and the measurement of ice pressures on offshore structures, can be carried out. The article briefly describes the tank, which is designed for model scales between 1/5 and 1/80 and measures 20 by 6 m; water depth is 1.8 m. Freezing rate is 3 mm/hr, freezing temperature is -20 deg. C, and ice thickness is 30 to 100 mm. Test data are transmitted to a data collection room and analysed almost simultaneously.
