Abstract
In order to monitor the performance of a vessel in calm seas it is important to ensure that the operational parameters are not biased by weather conditions. This paper makes a comparison between the relationship of true wind speeds obtained from on-board anemometer measurements and hindcast MetOcean data with the wave heights obtained from the MetOcean data. The insights obtained from the correlations between wind and waves is used to make a comparison calm water model derived from ‘wind-wave’ filtering and data filtered using only the wind speed. Finally, the increase in shaft power with respect to wind speed and wave heights for discrete intervals is presented. The results presented indicate that an average decrease of 4-5% in shaft power is seen when including an additional wave filter in the calm water model. However, this discrepancy improves when a stricter wind speed filtering is used.
