scope:

This International Standard 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 percussive pile driving is as part of an assessment of impact on aquatic fauna required by regulatory frameworks. This standard describes a generic approach to measurements that can be applied to different regulatory requirements. This standard is suitable for measurement of percussive pile driving undertaken for offshore installation of foundations (e.g. 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 standard does not cover measurement of the sound radiated by vibropiling or sheet piling. This standard does not cover piling in water of depth less than 4 m or greater than 100 m.
