This part of IEC 62600 provides uniform methodologies to consistently characterize the sound produced by the operation of marine energy converters that generate electricity@ including wave@ current@ and ocean thermal energy conversion. This document does not include the characterization of sound associated with installation@ maintenance@ or decommissioning of these converters@ nor does it establish thresholds for determining environmental impacts. Characterization refers to received levels of sound at particular ranges@ depths@ and orientations to a marine energy converter. Informative Annex B provides guidance on additional measurements that would be necessary to estimate source levels. The scope of this document encompasses methods and instrumentation to characterize sound near marine energy converters@ as well as the presentation of this information for use by regulatory agencies@ industry@ and researchers. Guidance is given for instrumentation calibration@ deployment methods around specific types of marine energy converters@ analysis procedures@ and reporting requirements. This document is applicable to characterization of sound from individual converters and arrays. This document primarily describes measurement procedures for individual converters@ with extension to arrays discussed in informative Annex A.
