全回转推进器应用于破冰/科考船的技术特点、现状及水下噪声控制措施研究

Technical Characteristics,State-of-Art and Underwater-Radiated Noise Control Measures for Application of Azimuth Thruster on Icebreaking/Oceanographic Research Vessel

全回转推进器在满足更低水下噪声辐射的破冰科考船上应用,仍未有工程实例,文章通过调查分析全回转推进器的技术应用特点和实船应用情况,结合DNV·GL和CCS规范中最高水下噪声要求,分析提出全回转推进器对水下噪声控制措施的建议以及吊舱最前沿的噪声模拟计算技术措施,为更高水下辐射噪声要求下的破冰船科考船装备全回转推进系统集成选配及设计提供参考。

There i no engineering case for the application of the azimuth thruster on the icebreaking oceanographic research vessel which can meet the requirements of the lower underwater-radiated noise yet.The suggestions on the control of the underwater noise for the azimuth thruster and the most up-to-date technologies for the simulation and calculation of the pod noise are proposed based on the investigation and analysis of the technical application characteristics of the azimuth thruster and the application in full-scale ships,combining with the highest underwater noise requirements in the DNV·GL and CCS rules.It provides reference for the integrated selection and the design of the azimuth propulsion system equipped on the icebreaking oceanographic research vessel under the higher requirements of the underwater-radiated noise.
