Wave Energy Prize - Official Finalist Team

Waveswing America seeks to demonstrate the benefits of sub-sea pressure-differential point absorber wave power generators for the production of utility scale power from offshore ocean sites. The team is building on significant past research work to deliver a device with unrivalled economics, power density and efficiency.

Update: Congratulations to Waveswing America on winning 3rd place in the Wave Energy Prize competition!

Round 1 Model Development

Working in close collaboration with AWS Ocean Energy, our engineers took the 1:50 scale model from a collection of sketches and outline dimensions through to a fully engineered physical model, ready for tank testing. Our activities included:

  • Working up concept sketches to a compact, functional design, using a combination of off-the-shelf components and bespoke parts;
  • Production of full CAD assembly in SolidWorks;
  • Specification of off-the-shelf components and materials;
  • Specification of, and supplier engagement for, air damper and magnetic displacement sensor;
  • Design of bespoke end cap and connector parts (incorporating seals and component supports) for production using rapid prototyping techniques;
  • Design and analysis of strain gauge solution for force measurement;
  • Design of air reservoir.

For Round 2, a larger and more complex model was required, incorporating a linear motor on a gimbal arrangement and a more complex bearing arrangement for low resistance in motion. Starting from concept sketches, and building the design around the dimensions and forces of the central linear motor component, we took the 1:20 scale model from concept through to a functional design. In order to meet the tight deadlines before tank testing, the model was designed as a kit which was then built up by our colleagues at 4c Design in their workshop facility. Our activities included:

  • Incorporation of learning from Waveswing America’s tank testing of the first model;
  • Working up concept sketches to a compact, functional design, using a combination of off-the-shelf components and bespoke parts;
  • Production of full CAD assembly in SolidWorks;
  • Specification of off-the-shelf components and materials;
  • Specification of load cells, magnetic displacement sensor, and inclinometer;
  • Design of bespoke end cap and connector parts (incorporating seals and component supports) for production using rapid prototyping and traditional machining techniques;
  • Production of detailed BoM and full assembly drawings to facilitate fastest possible assembly by 4c Design.
