某80000载重吨半潜船压载透气系统设计研究

Design and Research of Ballast System and Venting System on 80000 DWT Semi-Submersible Vessel

针对某大型半潜船的船型特点,开展对其压载和透气系统的设计。在确定全船压载系统的基础上,明确了该船透气系统为透气总管式,并以此为研究对象,提出了避免透气总管系统造成相关舱室累计进水的具体措施,分析研究了在最恶劣破舱条件下透气系统的安全性。

The ballast system and venting system are designed for the large semi-submersible vessel according to its characteristics.Having decided upon the ballast system of the whole ship,the venting system of the ship is determined as the common venting piping system.Specifi c measures are proposed to avoid the cumulative water infl ow of the relevant tanks caused by the common venting piping system.The safety of the venting system are also analyzed under the worst damage conditions.
