BS ISO 18406:2017描述了用锤击打桩过程中产生的辐射水声测量方法、程序和测量系统。测量冲击打桩过程中辐射的声音的主要动机是作为监管框架要求的水生动物影响评估的一部分。本文件描述了适用于不同监管要求的通用测量方法。本文件适用于海上风电场、石油和天然气平台以及其他近海结构物（如桥梁基础和水上可再生能源装置）施工中使用的基础（单桩、导管架、三脚架等）海上安装的冲击打桩测量。本文件不包括振动辐射声音的测量- 打桩或板桩。本文件不包括在深度小于4 m或大于100 m的水中打桩。本文所述的程序提供了测量指南，以满足以下目标:例如，为了监管目的，在打桩期间监测水源输出；在比较不同建筑项目的打桩噪声时提供一致性；用于验证建模或预测。本文件仅涵盖冲击打桩过程中辐射声场的测量。本文件的范围不包括暴露指标的评估或暴露标准的使用。未试图规定生成声源附近声场图的方法。在本文件的规范性部分中，描述了在打桩的特定范围内测量声场的要求和程序。 在本文件的这一部分中，没有提供与声源和接收器之间的传播路径（例如声源电平）无关的声学输出度量的确定程序。理想情况下，这样的指标会有一些预测效用（例如，在计算噪声影响区和噪声地图时）。然而，附录a中提供了一些关于确定可能的声输出指标的信息。本文件仅涵盖水柱中声压的测量。该范围不包括由于传播的声波或由穿过海底的波引起的海底振动而在水柱中测量声质点速度。这种排除并不意味着这些措施不重要；事实上，它们在评估对水生生物的影响方面的重要性已经得到承认。然而，在起草时，这些数量的测量还不够成熟，无法实现标准化。 交叉引用:ISO 18405:2017 IEC 60565:2006IEC 62127-1:2007 Ed 1IEC 60500:1974IEC 61260-1:2014ISO 17208-1:2016ISO/IEC指南98-3:2008 Ed 1ANSI/ASA S12。64-2009/第1部分购买本文件时可获得的所有现行修订均包含在购买本文件中。

BS ISO 18406:2017 describes the methodologies, procedures, and measurement systems to be used for the measurement of the radiated underwater acoustic sound generated during pile driving using percussive blows with a hammer.A major motivation for undertaking measurements of the sound radiated during percussive pile driving is as part of an assessment of impact on aquatic fauna required by regulatory frameworks. This document describes a generic approach to measurements that can be applied to different regulatory requirements.This document is suitable for measurement of percussive pile driving undertaken for offshore installation of foundations (monopiles, jackets, tripods, etc.) used in construction of offshore wind farms, oil and gas platforms, and other inshore structures such as bridge foundations and aquatic renewable energy devices.This document does not cover measurement of the sound radiated by vibro-piling or sheet piling. This document does not cover piling in water of depth less than 4 m or greater than 100 m.The procedures described herein provide guidance on making measurements to satisfy the following objectives:to monitor source output during piling, for example, for regulatory purposes;to provide consistency in comparison of piling noise from different construction projects;for validation of modelling or predictions.This document covers only the measurement of the sound field radiated during percussive pile driving. The scope of this document does not include the assessment of exposure metrics, or the use of exposure criteria.No attempt is made to prescribe a methodology for generating maps of the acoustic field in the vicinity of the source.In the normative part of this document, requirements and procedures are described for measurement of the sound field at specific ranges from the pile being driven. In this part of the document, no procedure is provided for determination of an acoustic output metric that is independent of the propagation path between source and receiver (such as a source level). Ideally, such a metric would have some predictive utility (for example, in calculating noise impact zones and noise maps). However, some information on the determination of a possible acoustic output metric is provided in Annex A.This document covers only the measurement of sound pressure in the water column. The scope does not include measurement of sound particle velocity in the water column due to the propagating sound wave, or seabed vibration caused by waves propagating across the sea-floor. This exclusion does not imply that such measures are unimportant; indeed, their importance in assessing the impact on aquatic life is recognized. However, at the time of drafting, measurement of these quantities is not yet mature enough for standardization.Cross References:ISO 18405:2017 IEC 60565:2006IEC 62127-1:2007 Ed 1IEC 60500:1974IEC 61260-1:2014ISO 17208-1:2016ISO/IEC GUIDE 98-3:2008 Ed 1ANSI/ASA S12.64-2009/Part 1All current amendments available at time of purchase are included with the purchase of this document.
