Abstract: Crude oil inloading and offloading system is the most important and complicated units in Floating Storage and Offloading (FSO).Its selection,composition,arrangement,and operation process including stern infloading equipment,offloading mooring equipment,and stem single point mooring equipment were introduced briefly in this paper.Meanwhile,the characteristics and key points of stern infloading system and stem offloading system design was analyzed.The stern vertical reel type inloading equipment and stem turret single point mooring equipment selected in this paper had a worldclass level in the aspects of operation,maintenance,and security,which can provide references for the equipment selection in the FSO modification design.
Keywords: FSO; crude oil transfer system; inloading units; offloading units
浮式储油卸油船(Floating Storage and Offloading,FSO)是集内输、存储和转驳为一体的海上原油中转站,具有适应水深范围广、移动灵活和储油量大等特点,是海洋石油开发中非常重要的工程设备之一[1].与浮式生产储卸油装置(Floating Produciton Storage and Offloading,FPSO)不同的是,FSO上没有生产模块,不能对开采出的油进行处理.近年来随着原油价格下跌,散货及油轮市场越发不景气,大量大龄油轮又面临新的规范规则限制,亟待改装或报废.与此同时,海上油田开发突飞猛进,船舶改装技术日益进步.选用先进的、适用的技术与设备,将废旧超大型油轮(VLCC)改装为FSO/FPSO,具有更高的性价比,有利于降低初始投入,提高运营效益,能早日收回成本[2].因此,探讨对FSO原油输储驳系统内输与存储、浮筒外驳、油船转驳三大关键工艺流程及其相应的关键设施和适用设备的选用……
