The purpose of Technology Gate 2 is to evaluate the likelihood of each team’s success in achieving the ACE threshold if they were to test a 1/20th scale model of their device in the MASK Basin. As a first step in this evaluation process, judges will consider each Qualified Team’s Model Design and Construction Plan to determine if the team exhibits a reasonable understanding of the effort, tasks, timeline and materials that will be needed to design and build a 1/20th scale model. The team will not proceed and will be eliminated from the Wave Energy Prize if the plan is deemed not credible.
If the judging panel determines that a team’s plan is credible, it will then use the following information to evaluate the likelihood of the proposed WEC technology concept in satisfying the required threshold value for ACE during the 1/20th scale testing:
- The capture width of the physical 1/50th scale model from the 1/50th testing, scaled up to full scale.
- Numerical modeling results of the 1/50th scale wave environment (at full scale) and the determination by the judging panel of how well the numerical model predictions correlate with scaled-up experimental measurements. This includes absorbed power, motions, and forces.
- Revised Technical Submission and its re-evaluation using the TPL.
- Predictions of ACE (in m/$M) that can be expected in the MASK Basin testing, as determined by the judges, with support from the National Laboratories.
The judges will score each of the above four criteria on a scale of 1 to 9. Then, they will calculate an overall combined score by computing a weighted average of the four individual scores. Qualified Teams will then be ranked from the highest overall combined score down to the lowest; up to 10 will be named Finalist Teams and up to two Alternate Teams will be identified. If the judges and/or Small-Scale Test Facilities are unable to test, measure and analyze the 1/50th scale WEC device in order to adequately determine absorbed power, the device will be eliminated from the Wave Energy Prize.
