Project Achievements

Laboratory test of first generation device module has been conducted and the device module achieved accuracy and amplification factor as expected but performance achieved was near by 60%. Collected data and analysis of device function drew us to design a new device design.

The developed new second generation design was more compact in comparison to first generation design. We reduced the size of design to nearby 55% of its original design without compromising to its performance. Definitely this new design will reduced the raw material and the time taken to build the offshore OWC.

The device has given maximum performance with accurate double amplification factor according to plan. We tested the device for several hours. The device has shown smooth functionality without any hassle and we achieved our expected goal.

Now by analyzing the data and performance of second generation device we established the third generation conceptual design for pilot and commercial sized plants, which will perform to its optimal performance.

The one mould design will help to perform fast assembly of device by Nut-Bolt technology; further this will reduce the time to assemble the device and the manufacturing cost.

The new design will use nearby 70% of Fiber Reinforced Plastic (FRP) or similar non-corrosive material, which will reduce the manufacturing cost with compare to Marin Grad Steel and overall maintenance cost and time, further the use of Fiber Reinforced Plastic (FRP) or similar non-corrosive material will extend its life to 35-40 years until their complete overhaul is needed.

We designed the third generation device in such a way, that it will defuse the oncoming waves and reduce the drag on device in stormy weather condition also. In the event of upcoming storms, the system automatically submerses the buoyant device to the lower level of wave level, to protect the system mechanical damage.

The applied fix rudder system automatically maintains the direction and directs the buoy to the exact directions of the upcoming wave, which in turn maximizes the power production.

Considering to the turbine, it is proven that impulse turbine gives more performance than wells turbine. We have planned to put Redial-Impulse turbine in our system to extract the energy. In practical, to the inwards flow of air direction the radial-impulse turbine gives maximum performance while to the outward direction it gives very poor performance. To overcome this problem of performance we have designed the new radial-Impulse turbine in such a way, that it will maintain the same air compression ratio to its both inward and outward direction of air flow. This will give steady power output without decreasing it performance in stall state of wave’s directions in comparison to Wells turbine.

We have registered this turbine design for its patent and soon this design will undergo for its laboratory test and further modification.
