FPSO单点系泊系统安装及回接技术

Installation and Hook-up Technology for FPSO Single Point Mooring System

单点系泊系统作为浮式生产储油卸油装置(Floating Production Storage and Offloading,FPSO)的核心组成部分,需在FPSO进入安装现场之前完成安装,随后FPSO进入安装现场进行回接。以我国南海某具体工程项目为背景,全面、系统地介绍FPSO悬链腿单点系泊系统的安装及回接方法,并采用OrcaFlex分析软件对各个施工步骤进行相关的模拟分析。该单点系泊系统的整个安装过程可分为抓地锚安装、下段锚腿铺设、锚腿张紧、上段锚腿铺设、单点浮筒拖航及就位和锚系回接单点浮筒等6个阶段。

Single Point Mooring(SPM)system is one of the core components of FPSO(Floating Production Storage and Offloading)facility,which should be installed before FPSO is towed into the field for subsequent hook-up.This paper systematically introduces the installation and hook-up methods of a SPM system for a specific project at the South China Sea,where OrcaFlex software is used for the simulation and analysis of each operation stage.The installation process ofthe SPM system consists of6stages,i.e.deployment of anchor,laying the lower part of anchor leg,preload of anchor leg,laying the upper part of anchor leg,towing and positioning of the single point buoy,and the hook-up between themooring system and the sing point buoy.
