An onboard vacuum suction oil recovery system has been developed. The system employs a high-power vacuum blower to suck and transfer oil slicks from the sea surface together with large amount of water and air in the gas-liquid multiphase form. This paper mainly presents the performance test results with a large-size model in the Simulation Tank for Oil Recovery in Maritime Situations (STORMS) in PARI. The tests covered various aspects including oil recovery performance such as sensitivity to sea condition or emulsification as well as design issues such as power required for driving blowers, how to cool the blower or how to control the suction rate, etc. Throughout the whole tests, the system generally worked well. The test results have been applied to the oil skimming system mounted on ISHIZUCH--an oil recovery vessel owned and operated by MLIT, which has been fully refitted and has come back in service this spring.
