Australian Wave Energy Atlas - Garden Island Case Study Numerical Wave Modelling

Brief description

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. For this study, a total of five oceanographic instrument deployments were undertaken. To support this field program, a series of numerical simulations using a phase-averaged wave model capable of including of wave energy converters (WECs).
The numerical model used is the Sandia National Laboraties SWaN model (SNL-SWAN v1.0, http://snl-waterpower.github.io/SNL-SWAN/)
Sets of model simulations are available over each instrument deployments; however these data sets are the gridded bulk statistics
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.
For deployments 1-4 bulk wave statistics significant wave height, mean wave direction, smoothed peak period and directional spreading of the waves.
This work was funded by the Australian Renewable Energy Agency and CSIRO Oceans and Atmosphere, and Carnegie Clean Energy provided access to site.
Lineage: The numerical model used is the Sandia National Laboraties SWaN model (SNL-SWAN v1.0, http://snl-waterpower.github.io/SNL-SWAN/) was used to estimate the coastal wave field with and without Wave Energy Converters (WECs) during five in situ instrument deployments.
