CETO Commercial Scale Unit

The CETO 6 design builds on the experience gained in all previous CETO generations and incorporates some important improvements.

The diameter of the buoyant actuator has the most significant influence on power output and has been increased to approximately 20m from the 7m diameter 80kW unit successfully tested at the Garden Island site in 2011 and the most recent 11m diameter, 240kW units tested in 2015 at the same site.

Apart from being larger, CETO 6 will also incorporate the power generation offshore, inside the buoy rather than onshore as with the previous CETO 5 design being deployed for the Perth Wave Energy Project. Locating the power generation within the buoy removes the need to attach pumps, accumulators and other hydraulic components to the seabed, avoiding the requirement for offshore heavy lift vessel capacity and reducing the offshore installation and maintenance time and cost. The CETO design, incorporating subsea generation and transmission of electrical power will allow Carnegie to take advantage of deeper, more distant to shore wave resources significantly increasing the size of the commercial market for CETO as well as allowing greater responsiveness in the CETO control system.
