Prediction of underwater noise for environmental impacts: Evaluation of a commercial vessel and offshore structure

摘要

The study of the environmental impact of underwater noise has become increasingly visible. Recently, underwater noise regulation has become an international concern. Therefore, the mitigation of underwater noise emission in operation is an important factor in the design of environmentally friendly ship and offshore structures. As a shipbuilding company, in order to meet the increasing demand for an eco-friendly vessel, Samsung Heavy Industries Co., Ltd. has developed a standard procedure to estimate underwater noise in the initial design phase. This procedure can be used both to design a low-noise vessel and also to evaluate environmental impact. In this paper, the procedure employed to estimate underwater noise is presented with results from full-scale measurements.
