张力腿平台下浮体通风系统设计研究
Ventilation system design and research on column and pontoon of tension leg platform
摘要：
结合国内首个张力腿平台项目的前端工程设计，对下浮体通风系统的设计进行了研究。通过分析下浮体通风系统设计前提、危险区划分、各类舱室通风方式选择、通风量计算、系统运行方式等设计原则，明确了各类舱室的通风系统设计要求和风管系统的设计要点，形成了完整的张力腿平台下浮体通风系统设计方法。

Abstract：
Combined with a first front-end engineering design in China, studies the ventilation system for column and pontoon of tension leg platform. Analyses the system design principle including design premise of ventilation system, hazard area division, ventilation type selection, ventilation rate calculation, and the operation mode, clarifies the ventilation system design requirements for all kinds of tanks and main design points of air duct, and forms a complete ventilation system design method for column and pontoon of tension leg platform.
