Hann-Ocean delivered the world’s first wave energy converter array for small waves in Singapore
With the support of Spring Singapore’s Technology Innovation Grant and in partnership with SembCorp Marine Technology, Hann-Ocean Energy (HOE) has developed a twin-chamber wave energy convertor (WEC) “Drakoo” (Dragon King of Ocean) that allows for low cost electricity generation from all waves scales (0.2m – 5.5m) and hence very suitable for both shallow water and deep seas deployment.
The internationally patented DRAKOO transforms sea waves into a continuous water jet driving a hydro turbine generator onboard. The Drakoo has been tested successfully in national research laboratories, at sea and in deep wave flume. The performance of DRAKOO has also been validated by Narec UK for achieving a peak wave energy capturing efficiency beyond 90%. The 1st commercial model Drakoo-B0016 has an overall conversion efficiency (waves to electricity) of up to 55%.
The unique modular design and the use of highly efficient, proven hydro turbine technology out-perform all its’ competitors in the current market. Drakoo is also made to last in stormy seas with an in built pressure release mechanism. It is not only eco-friendly but also will not impose any danger to marine lives due to the filter effect of its Inlets.
Hann-Ocean Energy successfully delivered its first commercial supply of wave energy convertors Drakoo-B0004 (16kW in total) to Jurong Shipyard Pte. Ltd on 29 Nov 2012. The WEC array will be installed at the new Jurong Mega yard at Tuas View Sea, Singapore to power the shipyard’s jetty.
The Drakoo-B0004 module is the world’s first WEC that works under very small wave conditions (0.2m ~ 0.6m). Hann-Ocean is collaborating with Nanyang Technological University (NTU), Singapore to assess the wave energy resource in Singapore coastal sea. Thus, this Drakoo technology, which is fully developed in Singapore, will demonstrate the economic feasibility of generating electricity using small wave energy resources.
Hann-Ocean Energy will officially launch its first commercial product of wave energy convertor Drakoo-B0004 in World Future Energy Summit 2013 (Booth No. 9622) on 15-17 January 2013 to be held in Abu Dhabi, UAE. A technical presentation about the Drakoo Type-B technology development will be given by the inventor Mr Henry L Han at the Technology Exchange Platform located inside the WFES exhibition hall on 15th of January, 2013 at 14:00 – 14:25hrs.
