摘要：

目前我国深水海域处于开发早期阶段,较适合采用既有钻井功能又集成了采油,储油功能的浮式生产钻井储卸油装置(FDPSO),作为独立生产装置,可以大幅降低油田初期开发费用.选取一种新型的八角形FDPSO结构,基于深海环境条件和装载工况,建立整体结构数值模型,依据三维辐射绕射理论和谱分析法计算波浪载荷,确定设计波参数,将设计波载荷传递到整体结构有限元模型,最终得到了总体结构的应力分布规律.研究结果可为我国深远海油气田早期开发的FDPSO结构设计提供理论参考.

Abstract:

Nowadays, the deep water in China is in the early developing stage, and it adapts for floating drilling, production, storage and offloading structure (FDPSO), which integrates the functions of drilling, production and storage. FDPSO can reduce much expense for early development of oil field. In this paper, a new-style eight-square FDPSO is studied. Based on the complex environment in deep water and the load cases, the global structure model is built. According to the three-dimensional potential flow theory and spectra-based analysis method, the wave loads are calculated and design wave parameters are decided. By transferring the design wave loads to global structure model, the structure stress is obtained. The calculation results can provide theoretical reference for the design of FDPSO working in the oil fields of deep water.

Key words: floating drilling,production,storage and offloading structure, design wave method, finite element model, global structural strength
