深水半潜式生产平台噪声预报研究

On noise prediction of a semisubmersible platform

噪声预报是海洋石油平台设计建造领域中一项非常重要的研究课题。海洋石油平台在正常工作期间,平台上各个设备的正常运转所产生的振动和噪声,不仅会造成设备元件的共振和机械应力疲劳,还会对海上作业人员的身心健康造成一定的危害。文章基于VA One软件对深水半潜式生产平台进行噪声研究,分别对平台开放式区域和封闭生活工作舱室进行噪声预报分析,并对典型舱室进行降噪处理。

Noise prediction is one of the important research subjects in the design and construction of marine oil platforms.The vibration and noise generated by the normal operation of each equipment on the marine oil platform will cause the resonance of the equipment components and mechanical stress fatigue,and will adversely affect the physical and mental health of the offshore crew.This paper studies the noise of jacket platform by the VA One software.It performs the noise prediction analyses of the opening regions and the closing living compartments,and achieves the noise reduction for the typical compartments.
