41 Wave-by-wave assessment of Power Production TS-100/101 Tecnalia Experience & conclusions so far - Power performance assessed using: 3 hours, 1 hour, 20 min timescales. - So far, dispersion in power performance estimation generally decreases going from 30 min to 1h & to 3h sampling durations. More data needed to assess if this is more than simply the effect of sample size. - Now examining finer timescales to help assess: the effect of phenomena such as wave groupings on power assessment; the influence of wave resource sample duration on power assessments, including the common oceanographic practice of hourly 17 minutes samples.

OPERA Preliminary results Page 15 Open Sea Operating Experience to Reduce Wave Energy Cost

45 Moorings TS10 - UEXE Experience & conclusions so far Difficult to isolate the impact of moorings on power performance: - In this case, device motions are influence by the PTO and the influence of chamber pressure. - However, there a significant number of factors that may be impacting results & none can be isolated when examining real sea data. - Currently determining if any impact can be isolated using the numerical model. - Will provide feedback on the difficulties experienced and consider the significance of different technologies when assessing the impact of moorings.
