摘要
阐述了集天然气预处理、液化、储存、外输为一体的新型海上浮式装置FLNG总体设计中的几项关键技术。提出控制船体运动性能的重要性,从主尺度选择、线型设计和典型配载工况等方面入手进行分析,确定250,000m3 FLNG船体主尺度,以确保上部生产系统高效率的正常作业。针对LNG货物围护系统,提出薄膜型(双排舱)和SPB独立舱型两种货物围护系统方案,并从上部模块支墩设置和隔离舱加热等方面对这两个方案进行比较。论述FLNG冷却海水供应系统的特点及其与常规海底门取水方法的不同之处,提出舷外海水提升泵取水的可行方案。
This paper elaborates some key technology aspects in general design of FLNG, which is a floating LNG production unit together with natural gas pre-treatment, liquification, storage and offloading system. Hull’s main dimension, lines and typical loading conditions are studied, and then a FLNG with main dimension of 250,000m3 is provided to get good hull motion and assure high efficiency of topside production system. Characteristics of LNG cargo containment system for FLNG unit are described, and membrane type of tank is compared with SPB independent tank. Seawater lift submersible electric pump system is proposed as a cooling seawater supply system for topside liquification unit.
