摘要： The present invention provides a method of protecting one or more flexible risers which can carry a riser fluid, for instance a hydrocarbon production fluid such as natural gas, to or from a floating structure and an apparatus therefor, said method comprising at least the steps of: (a) providing a floating structure (100), one or more flexible risers (10), each of said flexible risers carrying a riser fluid and having a first end (20) connected to the floating structure (100) and a second end (30) on the sea bed (500) and in fluid connection with one or more riser fluid reservoirs (250); (b) closing the fluid connection between the one or more flexible risers (10) and the one or more riser fluid reservoirs (250); (c) replacing at least a portion of the riser fluid in one or more of the flexible risers (10) with a protection fluid, wherein the density of said protection fluid is greater than the density of said riser fluid.
摘要翻译：本发明提供了一种保护一个或多个柔性立管的方法，所述柔性立管可以承载诸如天然气的烃产生流体到提升管流体或浮选结构的提升管流体和其装置，所述方法至少包括以下步骤：（a）提供浮动结构（100），一个或多个柔性提升管（10），每个所述柔性提升管承载提升流体并且具有连接到浮动结构（100）的第一端（20）和第二端（500）上并且与一个或多个立管流体储存器（250）流体连接; （b）关闭所述一个或多个柔性提升管（10）和所述一个或多个立管流体储存器（250）之间的流体连接; （c）用保护流体替换一个或多个柔性立管（10）中的提升管流体的至少一部分，其中所述保护流体的密度大于所述提升管流体的密度。
