A comparison of stresses calculated using the ABS/DAISY system with those measured on board the SL-7 Containership is undertaken to verify the analytical procedures used in assessing the strength of ships in a seaway. The comparisons and evaluations are performed for four different and progressively more severe technical conditions: dockside calibration, RMS stresses in head seas, instantaneous stresses in head seas and instantaneous stresses in oblique seas. The overall comparison between calculated and measured stresses for the dockside calibration is good where thermal effects were small but inconclusive elsewhere. The comparison of RMS stresses in head seas is generally satisfactory, using both the spectrum analysis approach and the equivalent regular wave approach, and the comparison of instantaneous stresses in head seas and in oblique seas is also good for the wave conditions considered.
