In stormy weather on January 2, 1997, the Russ23ian tanker "NAKHODKA" broke up at midship into two parts in the Sea of Japan just. off the Japanese coast. The recovery operation was hampered by high waves, and the most serious problem was the lack of equipment to recover the spilled oil operable in stormy weather. In 1998, corresponding to this accident, the Association for Structural Improvement of the Shipbuilding Industry (ASIS) initiated a three-year research and development project on large-scale recovery systems to collect highly viscous oil with a minimum kinematic viscosity of 0.1m^2/s for severe sea conditions. This paper focuses on the selection of an oil skimmer system suitable for recovery of highly viscous spilled oil emulsified under rough sea-state. The oil skimmer system is composed of a float, pump, hose, oil/water separator, etc. Dynamic simulations and tank tests were performed by using several types of floats for comparative evaluation. The basic design of the oil skimming and treatment system including various devices has been completed, based on constituent technologies, which are wave-response technology, highly viscous oil suction technology (reported on first report) and highly viscous oil collection technology.
