欧洲AQUO项目于2012年10月在欧洲研究框架的范围内启动，为期三年。最终目标是为政策制定者提供实用的指导方针和解决方案，以减少船舶噪声辐射造成的水下噪声足迹。对于正在考虑的海域，缓解方案可分为两类：第一类是减少在该区域航行的最嘈杂船只的水下噪音排放，第二类是与船舶交通管理有关的。本文件针对第一种类型，目的是评估不同缓解措施的效率，对应于AQUO项目专门的任务5.2。首先，概述了可能采取的缓解措施的全面清单。然后，定义了与参考舰船相对应的研究案例，并测试了几种缓解措施，以估计舰船源级(水下辐射噪声)的降低。为了实现这一任务，使用了不同的建模技术和来自AQUO项目先前任务的实验结果。必须特别注意内部机械和发动机辐射噪声部分的相对重要性，以及螺旋桨辐射噪声部分的相对重要性(S)。对结果的分析可以确定最有希望的解决方案。
The European AQUO project started in October 2012, in the scope of the FP7 European Research Framework, for three years duration. The final goal is to provide policy makers with practical guidelines and solutions, in order to mitigate underwater noise footprint due to noise radiation from ships. For a maritime area under consideration, mitigation solutions can be split into two categories: the first one is to reduce the underwater noise emission of the noisiest vessels sailing in the area, and the second one is related to ship traffic management. The present paper addresses the first type, and the purpose is to assess the efficiency of different mitigation measures, corresponding to the dedicated task 5.2 of AQUO Project. First, an overview of a comprehensive list of possible mitigation measures is presented. Then, study cases corresponding to reference vessels are defined and several mitigation measures are tested in order to give an estimation of the reduction of ship source level (underwater radiated noise). To achieve this task, different modeling techniques and experimental results from previous tasks of AQUO Project are used. Special care must be taken on the relative importance of the part of radiated noise due to internal machinery and engines, and the part due to propeller(s). The analysis of the result allow identifying the most promising solutions.
