巴基斯坦某浮式液化天然气(LNG)码头控制系统的解决方案

为系统研究巴基斯坦某浮式LNG码头工程的控制系统设计方法,针对浮式LNG码头特殊的系泊、靠泊和作业要求,绘出适合浮式LNG码头的控制系统框架;详细阐述船岸连接系统、消防控制系统、靠泊及辅助控制系统等各子系统之间的相互关系以及各控制子系统的具体配置;根据巴基斯坦某浮式LNG码头平面布置条件,通过研究各国规范相关规定、并结合现行国内控制系统设计标准,总结出一套区别于常规LNG码头控制系统的设计思路和解决方案。结果表明,浮式LNG码头在常规LNG码头搭建控制系统框架的基础上,在数据传输通道、线缆合理布局以及主控对象选择等方面,有进一步优化提升的空间。

Solution to control system of floating LNG terminal in Pakistan

In order to systematically study the design method of the control system of a floating LNG terminal project in Pakistan,we focus on the special requirements of mooring,berthing,and operation for floating LNG terminals,draw the suitable control system framework,and introduce the relationship and configuration of subsystems including ship-shore linkage system,fire control system and auxiliary berthing system. Based on the layout condition of a floating LNG terminal in Pakistan,we study the relevant provisions of national standards and combine them with the current domestic control system design standard,and summarize an idea and solution for a control system different from normal LNG terminals. The results show that compared with control system establishment for normal LNG terminal,there are further optimizations space in data transmission,reasonable cable arrangement,and control object selection for floating LNG terminal.
