Uncertainty in Measurement of Ship Model Wave Profiles and Wave Pattern Resistance
Two sets of longitudinal wave cut data serve as the basis for estimating the measurement uncertainty associated with the ship model waves profiles and wave pattern resistance. The data was obtained from two similar frigate type hull forms tested over a speed range from Fn=0.25 to 0.5. Five wave probes were used simultaneously to measure wave elevations and from these measurements five parallel estimates of wave pattern resistance were obtained. The elemental bias and precision error sources which are encountered are grouped and discussed according to three categories; calibration, data acquisition and analysis.
