Noise prediction and reduction scheme of cabin air noise control about offshore nuclear power platform

As higher demands for ships and offshore working platforms are required by new standards, the control and optimum design of cabin air noise have attracted more and more attentions nowadays. In this paper, the theory of statistical energy analysis and overview of the full-band cabin noise prediction software named VA One are introduced firstly, and then the geometric modeling and simulation calculation of the marine nuclear power platform are implemented using the software. Comparing the simulation calculation results with standard indexes, a comprehensive noise reduction scheme for cabin air noise control of offshore nuclear power platform is proposed in the design stage, which can shorten the construction period, reduce the manufacturing cost, improve the comfort and safety of offshore nuclear power platform, and may bring out great benefit both in economy and in society
