This report consists of 5 items. The first one is the measurement of the friction and the abrasion between materials and ice. As materials, paints, FRP and FRTP are used. The coefficient of dynamic friction and the characteristic of the abrasion are investigated experimentally. The second one is the water absorption mechanism of the composite materials and its strength change. The water absorption mechanism is examined under low temperature and under pressure. The strength changes are tested by tension and bending. The third one is the measurement of icing on the hydrophobic materials. The adhesion of icing is examined by an impact test. The forth one is the precise measurement of CO_2 solubility coexisting with CO_2 hydrate. The last is the measurement of the surface tension of oils and the interfacial tension between oil and seawater. In the case of low viscosity oils, the surface tension of oil affects oil recovery efficiency and the interfacial tension between oil and water affects oil containment on water current by barrier. The test of separating ice from oil layer on water current with net is also conducted.
