Australian Wave Energy Atlas - Garden Island Case Study Field Program

CSIRO Oceans and Atmosphere conducted an intensive field program between Dec 2014 and Feb 2016 to assess the physical wave-current-morphodynamic response of wave energy extraction at Carnegie Clean Energy's Perth Wave Energy Project, located near Garden Island near Perth. The aim of the field program was to provide in-situ measurements of changes in incident wave spectrum and associated hydrodynamics adjacent to one or more wave energy converter devices to provide a necessary data stream for wave model verification. Five deployments were undertaken; First, instruments were deployed on a 34-m diameter ring around unit 1. This pre-deployment was aimed at investigating the non-linear interactions between the wave field and the WEC. The following four deployments were aimed at measuring the changes in the wave energy-frequency spectrum downstream of the WEC array. For the second and third deployments, all instruments were positioned in a triangular array downstream of the WEC array in the direction of the propagation of the known swell climate. The last AWAC deployment (deployment 5) occurred following the recovery of all WEC units. The AWACs were deployed in the same configuration as the previous deployment and this deployment acts as a control experiment to determine the natural variability of the wave field across the site.This work was funded by the Australian Renewable Energy Agency and CSIRO Oceans and Atmosphere, and Carnegie Clean Energy provided access to site. Lineage: Prior to each deployment, instruments were compas calibrated to ensure processed data meet manuafacturers specifications. Data were downloaded on recovery, and processed using proprietary Nortek software 'Storm'.澳大利亚联邦科学与工业研究组织海洋与大气分部（CSIRO Oceans and Atmosphere）于2014年12月至2016年2月期间开展了一项密集野外科考项目，旨在评估位于珀斯附近加登岛周边的卡内基清洁能源（Carnegie Clean Energy）珀斯波浪能项目内，波浪能提取作业所引发的物理波-流-地貌动力学响应。本次野外项目的核心目标是，对单个或多个波浪能转换器（Wave Energy Converter, WEC）装置周边的入射波谱及相关流体动力变化开展原位测量，为波浪模型验证提供不可或缺的数据流。 本次科考共完成5次仪器部署：首次部署中，科研人员在1号机组周围34米直径的环形区域布设观测仪器，该前置部署旨在探究波浪场与WEC之间的非线性相互作用。后续4次部署则用于测量WEC阵列下游的波浪能-频率谱变化。在第二次与第三次部署中，所有仪器均沿已知涌浪传播方向，以三角阵列形式布设于WEC阵列下游区域。第五次AWAC部署是在回收全部WEC机组后开展的。本次AWAC的布设配置与前一次部署完全一致，该实验作为对照试验，用于确定该研究区域内波浪场的自然变异性。 本项目由澳大利亚可再生能源署（Australian Renewable Energy Agency）与CSIRO海洋与大气分部联合资助，卡内基清洁能源公司提供了场地使用权限。 数据溯源说明：每次仪器部署前，均开展罗盘校准工作，以确保处理后的数据符合制造商技术规范。仪器回收后下载原始数据，并通过诺泰克（Nortek）专有软件《Storm》完成数据处理。
