LONG TERM PREDICTION OF OFFSHORE VESSEL RESPONSES FOR DESIGN AND OPERABILITY EVALUATION

This paper presents an approach to the prediction of long term responses of offshore vessels for design and operability assessments. The evaluation of the vessel responses takes account of the random variations of spectral shapes within the same sea-state due to sea/swell directionality and other oceanographic phenomena. The resulting response statistics which use this approach will not only simulate the average condition, but will also indicate the probability of the extreme conditions that may be encountered by the vessel during its mission time. The methodology is applied to offshore construction planning and transportation studies to illustrate the importance of the long term effects of ocean wave spectra in an overall design and operability assessment. A detailed mathematical development of the approach is also included in the Appendices.
