At the heart of Twin Ocean Power is a tri-body floating structure comprising six buoyant cylinders arranged into three independent buoy sets: a central main set and two outer sets. This configuration is aligned perpendicular to the wave direction and parallel to the wave crests, optimizing energy capture across varying sea conditions.

Each buoy set includes a central unit flanked by two cylindrical housings. Two direct power take-off (PTO) converters are positioned at each end of the central unit to convert wave energy into usable power. The PTO system converts bidirectional low-speed rotation into unidirectional high-speed rotation, maximizing energy efficiency. A torque limiter controls torque transfer from the output gearing to the alternator, preventing overload and ensuring system protection.

The buoy sets are connected by length-adjustable, pivoting arms, allowing each set to move independently. This design enables the system to adapt to unbalanced wave conditions, maintaining optimal performance under varying sea states. The modular design also simplifies transportation, assembly, and maintenance.

⚙ Key Innovations

· Direct Mechanical PTO: By eliminating complex hydraulic systems, the direct mechanical PTO enhances reliability and reduces maintenance needs.

· Modular Design: The system's modular architecture allows for easy scalability and adaptability to different marine environments.

· Wave-Aligned Configuration: Aligning the device parallel to wave crests maximizes vertical motion capture, improving energy conversion efficiency.

🌱 Environmental and Economic Benefits

Twin Ocean Power's design minimizes environmental impact by using fewer complex components and avoiding hazardous materials. Its buoyant structures reduce the need for large, energy-intensive components, lowering the carbon footprint of manufacturing and maintenance. Economically, the simplified design and modular construction reduce installation and operational costs, making it a cost-effective solution for renewable energy generation.

Testing and Validation

The Twin Ocean Power system underwent rigorous testing at the O.H. Hinsdale Wave Research Laboratory, supported by TEAMER funding. The comprehensive overview of the testing process, data analysis, and validation is publicly available, including power results from seven trials, raw data, and video recordings.

The Future of Ocean Energy

Ocean energy is a promising renewable resource, offering a constant and predictable power supply. With over 70% of the Earth's surface covered by oceans, wave energy has the potential to complement other renewable sources like wind and solar. Advancements in technologies like Twin Ocean Power are making ocean energy more viable and cost-effective, contributing to a sustainable and carbon-free future.
