Abstract

Offshore wind power has been currently attracting attention as part of the efforts of Sustainable Development Goals, and the cumulative installed capacity worldwide has increased more than 10-fold in the last decade. As the world’s energy sources shift from fossil to renewable energy, the increase of construction of offshore structures associated with marine development will likely generate undesirable underwater noise that is harmful to marine life living near construction sites. To reduce underwater noise and improve the marine acoustic environment, this study clarifies the generation mechanism and propagation behavior of underwater noise by pile driving and discusses how to reduce such noise.
打桩过程中水下噪声产生机理的实验研究
作为可持续发展目标努力的一部分,近海风力发电目前已引起人们的关注,在过去十年中,全球累计装机容量增加了 10 倍以上。随着世界能源从化石能源向可再生能源转变,与海洋开发相关的离岸结构施工的增加很可能会产生不良的水下噪声,对施工现场附近的海洋生物造成危害。为了降低水下噪声,改善海洋声学环境,本研究阐明了打桩水下噪声的产生机制和传播行为,并探讨了如何降低此类噪声。
