Abstract: Seakeeping tests were run with the nuclear ship OTTO HAHN in a stationary wind-generated seaway measuring the wave height and the ship’s responses speed, pitch, roll, and accelerations for course increments of about 22 degrees. The measured motion spectra are compared with theoretical ones that were calculated by a desktop computer utilizing the wave direction as inferred from the ship’s speed and the parametrized wave height spectrum as the input to transfer functions obtained from strip theory. A satisfying agreement is found for pitch and vertical acceleration at the reactor taking into account the statistical error of the measurements and the possible error of the wave spread assumed in the calculations.
