伴随世界经济的高速发展和能源消耗的日益增加,海洋油气开发已成为国际能源开发的主要领域。而海洋油气开发的加速发展,也使国际市场对海工装备的需求变得更为迫切。作为海上油气开发最重要的中转终端-单点系泊装置(Single point mooring system)主要用于大型油轮海上漂浮定位和原油的对外输送。同时将F P S O定位于预定海域,并输送井流,电力、通信等。单点系泊码头通常由一个能够漂浮在海面上的浮筒和铺设在海底与陆地贮藏系统连接的管道组成。浮筒漂浮在海面上,油轮上的原油通过漂浮软管进入浮筒后,从水下软管进入海底管线,输到岸上的原油储罐。本文主要基于锚链腿结构的单点系泊装置浮筒结构强度的规则进行研究,以保证系统的安全性。
With the rapid development of world economy and increasing energy consumption, offshore oil and gas development has become a major area of international energy development. The accelerated development of offshore oil and gas development, but also the international market for offshore equipment needs become more urgent. As the most important terminal for offshore oil and gas development, the single point mooring system is mainly used for the offshore floating positioning of large oil tankers and the outward transportation of crude oil. At the same time, F P S O is located at a predetermined sea area and transports well flow, electricity, communications and the like. A single point mooring wharf usually consists of a buoy that floats on the surface of the sea and a pipeline that connects the seabed to the onshore storage system. The buoy floats on the surface of the sea. Crude oil on the tanker enters the buoy through the floating hose and enters the submarine pipeline from the underwater hose to the crude oil storage tank on the shore. This paper mainly studies the rules of strength of buoy structure of single-point mooring device with chain-leg structure to ensure the safety of the system.
