PREDICTION OF SHIP RESPONSES IN LONG-CRESTED IRREGULAR WAVES (COMPUTER PROGRAM SRIW)

Current techniques for the prediction of ship motions in long-crested irregular waves are discussed. Format is provided for use of computer program SRIW which applies the method of linear superposition to regular-waves transfer functions obtained from experimental data or analytical predictions. Irregular wave spectra used are 323 point spectra measured at Station India in the North Atlantic and/or a series of mathematical spectra involving six parameters recently developed by Ochi.
