TEAMER
This is the Post Access Report for a TEAMER project conducted by Oscilla Power working with Oregon State University. Through this TEAMER work, OPI experimentally evaluated a new hull geometry for the Triton wave energy converter. The candidate geometry had been developed in collaboration with the University of Edinburgh using genetic-algorithm optimization. The preceding numerical study predicted an approximately 10% power-performance improvement in directional waves relative to the baseline hull.
The primary objective of the assistance was to validate the numerical model and hydrodynamic coefficients. Secondary objectives included identifying optimal PTO settings and examining load and power performance in short-crested seas.
Experiments were conducted in September 2021 at the Oregon State University Directional Wave Basin, with testing completed on September 24. The baseline and candidate models were tested side-by-side in the same incoming wave field, with separation reported to be sufficient to avoid interaction. Device 5 was selected to represent the baseline because it provided the best baseline data. Three representative US West Coast wave conditions were evaluated in head-on long-crested waves, 15-degree off-axis long-crested waves, and head-on short-crested waves.
The candidate hull performed worse than the baseline in all nine irregular-wave comparisons plotted in the completed-work summary. The expected numerical improvement was therefore not demonstrated experimentally. Subsequent comparison of WAMIT and NEMOH hydrodynamic results showed broad agreement but did not establish the cause of the prediction discrepancy. The robustness of the rapid white-noise AEP metric remained under investigation at the time of that summary.
The testing provided a direct experimental comparison of the optimized and baseline hulls and evidence to guide further model development. Recommended follow-on work is to reconcile the numerical fitness metric with the tank-test results before using the approach to select further geometries.
