摘要：

讨论了一种新型浮式生产系统的开发和研究.该系统具有潜在的市场开发经济性和可行性，特别是对深海及远海石油天然气的开发.新型的浮式生产系统是一种BMFPSO系统（Buoy Moored Floating Production Storage and Offloading system)，该系统应用一个垂直的浮式圆柱取代传统的应用在FPSO上的转塔(turret)系统且仍具有风标效应.BMFPSO的船体在风、浪、流的作用下可以围绕垂直的浮式圆柱作360°的旋转.浮式圆柱可以设计在船体内(或船体外)的悬臂中.除此之外，船体还可以沿着垂直的浮式圆柱作垂向移动，从而消除了传统的转塔式FPSO纵摇和垂荡耦合运动，减小了系统在极端海况以及正常作业情况下锚泊线及立管的张力.由于BMFPSO具有以上特征，采油树布置在平台上的干式立管系统和常规的钢管悬链线立管可以在BMFPSO上得到应用，从而使得立管系统的投资和维修更加经济和方便.除此之外，BMFPSO系统也可以用来作为液化天然气终端.

Abstract:

This paper discusses the development of a novel FPSO dry tree system by using a moored column-buoy connected to a ship shaped vessel.  The new system has a potential industry market compared with the traditional turret moored FPSO for deepwater offshore development, in particular for remote and deepwater locations where other pipeline infrastructure does not exist. The novel system is a Buoy Moored Floating Production Storage and Offloading system (BMFPSO). It uses a column-buoy instead of the turret in a conventional FPSO design for both internal and external turret system.  Similar to the turret, the column-buoy allows the vessel to weather vane about the column-buoy.  In addition, the vessel can move in vertical direction relative to the column-buoy. Thus the vertical motion of the column-buoy is de-coupled from the FPSO hull motion. The buoy will have a relatively small heave motion allowing the use of proven top tensioned riser technology. The motion characteristics of the system make it operable in a wide range of environmental conditions.
