Design Evolution

 
 

The latest versions of the Oceanlinx technology, greenWAVE and blueWAVE, are the culmination of more than 20 years of research and development. Oceanlinx technology is the only wave energy technology in the world to have underpinned by three different demonstrations platforms installed in the real ocean.  Each of these variations represented a logical sequence in the design evolution of the technology.

MK1, 2005

Port Kembla, New South Wales

This unit, known as the Mk1, being the first design concept, was a 500 tonne OWC chamber that sat on the seabed under its own weight and supported by anchors. It was installed at Port Kembla, about 100 km south of Sydney, Australia in 2006. The unit was subsequently decommissioned in 2007/ 2008.

The latest 'greenWAVE' design replaces this earlier version for application in nearshore shallow waters with a number of variants of the device to suit different applications.

MK2, 2007

Port Kembla, New South Wales

The next version of the technology was known as MK2. This floating unit was also installed at Port Kembla, and represented Oceanlinx’ first efforts at a floating OWC.

 

The single chamber floating unit device named 'ogwave' was also developed and designed in 2011-2012 for deployement in conjunction with offshore platforms. 

 
 

MK3PC, 2010

Port Kembla, New South Wales

In March 2010, Oceanlinx installed its MK3 (pre-commercial), also at Port Kembla. This unit was a cluster of eight floating OWCs.  

 

The unit was the first test platform to connect to the grid successfully producing high quality 100% clean electricity.

 

This design was the precursor to the blueWAVE device.

 

Evolution of the airWAVE turbine

1997 - 2012

 

1997 - 2009

The first Turbine


The first turbine addressed the problem of bi-directional flow by using a bi-directional turbine and using an active pitch control mechanism. Early experiments with this enhanced control capability revealed the potential for enhanced power extraction from an OWC.

2009 - 2012

Partial Admission Turbine

The Partial Admission Turbine used a well established single direction turbine design philosophy in a bi-directional application. This turbine highlighted the importance of correct aerodynamic design of the blades on the overall turbine efficiency.

2010 - 2017

airWAVE Turbine

The revolutionary development of the airWAVE turbine is that it forces and excites the water column motion of the OWC to extract energy from a higher density whilst working harmoniously with the OWC for the most efficient extraction of energy.
