This paper describes the structural design and construction of the oscillating water column “greenWAVE Energy Converter”, constructed during 2013 and planned to be deployed in shallow water off the South Australian coast in 2014. Rated initially at 1 MW, the greenWAVE unit will be dedicated to electricity production, although an option is available to also produce desalinated seawater. The unit base is constructed from reinforced concrete designed to international maritime codes, and will be founded in approximately 10-15m of water. The upper portion of the device extends above sea level, housing the airwave turbine and electrical control systems.
