BUTT JOINT TRUNCATED CONE TYPE FLOATING PRODUCTION STORAGE AND OFFLOADING SYSTEM

摘要

A butt joint truncated cone type floating production storage and offloading (FPSO) system, wherein a floating body is provided with an upper structural body (2) in a truncated cone shape and a lower structural body (3) in a truncated cone shape; in a combined state, a smaller bottom surface of the upper structural body (2) is fixedly connected with a smaller bottom surface of the lower structural body (3), to form a connecting surface; and the connecting surface is a full load water plane (1) of a floating structure. On this basis, functional modules for mooring positioning, oil and gas production, storage and offloading, and the like are arranged, to form a novel FPSO system. The floating body has the characteristic of being similar to a sandglass in appearance, and can overcome defects of a conventional FPSO system in seakeeping capacity, strength fatigue, pipeline layout and the like and expand functions thereof. The system is favorable for the integration of multiple functions of large-scale oil and gas drilling, exploitation, storage, production, processing, offloading and the like in various sea areas.
