AbstractUncertainty Analysis (UA) was performed on the results of the ship experiments. The objective is to quantify the level of uncertainty in the measured data. Both systematic (fixed) and random (precision) uncertainties associated with the measured ship motions, wave impact forces, and pressures were calculated. Potential uncertainty "error" sources were identified, and all significant elemental uncertainties were calculated. Both systematic and random uncertainties were added to compute the overall uncertainty. A discussion is presented regarding the effects and the contributions of various sources to the overall uncertainty as well as the propagation of the elemental uncertainties throughout all stages of the experimental program. Conclusions are reported and recommendations for future work are indicated.
