The problem of petroleum safety is closely related to national politics andeconomics security and becomes one of key for discussion in China. The floating oil storage systemhas been proposed as a new facility for Strategic Petroleum Reserve (SPR) in our country. There aresome differences in solving this problem. Although many of domestic research institutions arestudying the project of SPR, the research is separate, and lack of comprehensive consideration, andfails to make a complete and scientific demonstration in many aspects, such as oil storage capacity,selection of storage sites, storage facilities, technologic and economic feasibility, riskassessment, etc. Therefore, no mature and systematic petroleum reserve theories have been formed upto now. Peoples argue the issue of objective of SPR, function, mode, cost, effect, etc. There arestill many bifurcations, so, it is necessary to make more detailed demonstration, and provide somescientific decision-making strategy for the governments. In this paper, several significant problemsare solved, for instance, the option of SPR facilities, the research on the principalcharacteristics of floating oil storage vessels, the a-nalysis of mooring system for oil storagevessels, the design of breakwater and the calculation of failure probability, the risk assessment offloating oil storage system, etc. 展开更多
