LNG船液货装卸系统分析软件平台研究

提出了一种基于VC＋＋平台和数据库技术的LNG船液货装卸系统设计及分析的软件平台系统,详细介绍了其内容、结构和实现方法。该系统配有与管路阻力计算相关的管道、阀件、液货舱、附件等的数据库,能够按目标船的装卸要求,直接组态设计液货装卸系统管网系统。设计人员可以在每一个模型设计完成后直接进行优化并确定液货泵的排量、压头、液货管路的管径、长度等设计信息,仿真计算装卸过程中各时间段上的的流量、节点压力、剩余舱内液体容积等各项参数。不仅简化了液货装卸系统的设计过程和计算校核的时间,而且更加方便灵活。

An analysis software platform for cargo loading/unloading system on LNG carrier

This paper presents a software platform system for design and analysis of liquid cargo loading/unloading system for LNG carrier based on the VC＋＋ platform and database technology.With the database of pipe,valve,liquid cargo tank and accessories related to pipe resistance calculation,configuration design of the liquid cargo loading/unloading pipe network system can be directly implemented to meet the loading/unloading requirement of target carrier.Designers can directly optimize the designed model,determine the displacement of liquid cargo pump,pressure head,the diameter and length of liquid cargo pipe and other design information,and simulate the flow,node pressure,volume of liquid remained and so on during loading/unloading process.The most advantage of this system is the simplification of design process,the reduction of time for calculation and verification,as well as the increase of convenience and flexibility.This paper also introduces the content,structure and implementation of the software platform.
