摘　　要：随着海洋油气资源开发的发展,海洋平台工艺处理量越来越大,需要设置的释放火炬臂尺度也更大,超出了常规尺度范围。火炬臂长度增加必然导致结构重量增加和杆件尺寸发生变化,进而带来新的设计问题,如风激振动、风谱疲劳等。文中以南海某大型海上平台90 m超长火炬臂结构设计为例,探讨超长火炬臂结构形式的特点并进行了合理化的结构设计,对结构强度和疲劳损伤进行了评估,可为今后类似的结构设计提供参考。The oil and gas processing amount on platform becomes greater along with the development of offshore oil exploitation,so that it is necessary to use the bigger flare boom exceeding the normal size.The weight and member cross-section of flare boom increases when flare boom length extends,which will lead to the new design issues,such as wind-induced vibration and wind spectrum fatigue issues.Based on one 90 meters ultralong flare boom structural design of a huge offshore platform in South China Sea,the structural type was studied and optimized,and the strength and fatigue was assessed in this paper,which can provide a reference for similar structural design in the coming days.
