Offshore renewable energy

In the last 20 years, WRL has drawn on its long-standing experience in marine and coastal engineering to provide expert advice to the Australian Offshore Renewable Energy industry.

In parallel to its engineering activities, WRL has also been pursuing high-level academic research in the field of wave and tidal energy conversion, with a focus on both physical and numerical modelling. 

ORE study area

WRL can help identify the best locations for offshore renewable projects by providing clear assessments of the potential resource but also the risk associated with extreme events. Site selection and resource modelling are typically performed through a combination of field measurements and numerical modelling; providing developers, investors and operators with valuable information for design, installation and operational aspects. 

You can rely on our leading coastal engineering team to provide sound and independent advice on highly specialised aspects of offshore renewable projects such as cable routing and anchoring, device foundation and seabed scouring as well as environmental impact assessment. 

WRL’s considerable experience in physical modelling combined with our world-class testing facilities, makes it the ideal place for physical trials, from initial verification of the proof of concept, to device optimisation, survivability, and demonstration of project economics with large scale models. Test programs are specifically tailored to developer needs. Our specialist craftsman and fully equipped workshop can assist in the manufacture and calibration of fully instrumented models of marine renewable devices for scale model testing.
