110m CNG运输船货舱通风系统设计分析

Design and Analysis of Ventilation System for Cargo Hold of a 110m CNG Carrier

基于美国船级社(ABS)和印尼船级社(BKI)关于压缩天然气(CNG)运输船舶规范指南和规范的要求,对CNG运输船非惰性货舱高压气瓶保护和货舱温度的控制进行研究,计算货舱通风,合理布置货舱风机、管路及阀件附件等设备,布局优化应用到货舱通风系统中。通过研究分析一种安全性高、易控制、低成本的货舱通风系统,希望可以为此类船型货舱通风系统的设计和使用提供参考。

Based on the requirements of ABS and BKI on the rules and guidelines of compressed natural gas( CNG) transport ships,the protection of high-pressure cylinders in non-inert cargo holds and the control of cargo holds temperature of CNG transport ships are studied,the ventilation of cargo holds is calculated,the ventilators,pipes and accessories of cargo holds are reasonably arranged,and the layout optimization is applied to the ventilation system of cargo holds. Through the research and analysis of a kind of cargo hold ventilation system with high safety,easy control and low cost,it is hoped that it can provide a reference for the design and use of the kind of cargo hold ventilation system.
