摘　　要：深水半潜生产平台噪声源为常年工作的主机、泵撬、压缩机、生活区的配电盘、风机和空调等振动设备,以及船体立柱内机泵舱室的泵机、液压单元和立柱顶部的空调(服务于船体控制间)等振动设备。根据统计能量分析的基本原理,通过经验公式对暖通噪声进行估算,结合有限元方法和数值解析方法对半潜平台空气噪声、板格结构的频率和暖通噪声进行模拟分析,并对总噪声值预测结果进行合成,噪声模拟结果满足现场实测规范的要求。在此基础上,给出半潜生产平台全频段的噪声分析评估结果和设计建议,为半潜生产平台噪声控制提供技术支持。The noise of deep water semi-submersible production platform is sourced from the machinery working year round including the main engine,pumps,compressors,distribution boards in the living area,fans,air-conditioners and other vibration equipment,as well as the pumps inside the pump compartment of hull columns,the hydraulic units and the airconditioners at the column top(serving the hull control room).According to the principles of statistical energy analysis,the noises of the HVAC(heating and ventilation air conditioner)are estimated based on empirical formula,while the aerodynamic noise,the frequency of the plate structure and the noise of HVAC are simulated and analyzed with the finite element method and the numerical analytical method for the semi-submersible platform.The overall noise value is thus predicted,which satisfies the on-site measurement requirement.On this basis,the full frequency domain noise analysis and evaluation results and design suggestions are produced,which provides technical support for the noise control of semisubmersible production platforms.
