摘要
该文以浮式钻井生产储卸装置(FDPSO)为研究对象,建立全船有限元模型,采用有限元法计算了压载和满载工况的总振动。其次利用基于统计能量法的自研软件建立了船舶舱室噪声计算模型,计算结果表明,居住区域的舱室噪声满足MSC.337(91)《船上噪声等级规则》的舱室噪声标准限值要求,但是部分舱室噪声已经接近甚至达到噪声限值。
Global vibration and cabin noise on Floating Drill Production Storage and Offloading(FDPSO)are researched in this paper.Firstly,based on finite element method,whole ship model is build to calculate global vibration.Secondly,based on statistical energy analysis theory,a numerical model is build to compute ship cabin noise.The evaluated results show that cabin noise in accommodation space is satisfied for noise limit requirement in MSC.337(91)"Code on noise levels on board ships",but there are some cabin noises approach to the upper limit.
