Abstract: Vibro-acoustic analysis methods and related software for noise analysis of offshore platforms, FPSO structures, etc. were summarized and discussed. It was elaborated that there are two paths in transmission-airborne transmission and structural borne transmission, and both of them should be considered in the analysis. Moreover, it was indicated that the fast multi-pole boundary element method would play an important role in vibro-acoustic analysis in the future.

Key words: acoustics, offshore platform, noise analysis, vibro-acoustic coupling, fast multi-pole BEM

摘要： 以海洋平台上动力设备产生的大量振动噪声为研究对象，阐述海洋平台和FPSO等结构物声振耦合分析的数值方法以及噪声分析的相关软件。海洋平台上的噪声传播有空气声传播和结构声传播两种传播路径，计算分析时均需要考虑。快速多极边界元法是未来噪声分析的有效方法。
