海洋平台火炬臂长度影响因素分析

Analysis of Influencing Factors on Flare Arm Length of Offshore Platform

以国内某海洋平台为例,采用Flaresim、Phast软件,从热辐射、噪声及扩散等3个方面对不同角度、风速下的火炬臂长度进行系统分析。分析结果认为:热辐射是决定火炬臂长度的关键要素;火炬臂角度直接影响火炬臂长度,对于目标平台的火炬系统,决定工况点从火炬臂根部(0°~30°)变成修井机二层台面(45°~90°);当火炬臂角度为45°时,可最小化火炬臂长度,兼顾平台安全性与经济性。研究结果为火炬系统的初步设计提供参考。

Taken a domestic offshore platform as an example,the flare arm length under different flare arm angles and wind speeds is systematically analyzed from three aspects of thermal radiation,noise and diffusion by Flaresim and Phast Software.It is concluded that:the thermal radiation is the key factor to determine the flare arm length;the flare arm angle directly affects the length of the flare arm,for the flare system of the target platform,the determining operating point changes from the flare arm root(0°-30°)to the monkey board of the workover rig(45°-90°);when the flare arm angle is 45°,the flare arm length can be minimized and the safety and economy of the platform can be considered.The research results can provide reference for the preliminary design of the flare system.
