A STUDY OF WAVE-INDUCED VIBRATIONS (2ND REPORT)

As a continuation of the previous work, the study on wave-induced vibrations (springing) has been presented in this report. Model experiments in irregular waves have been carried out. Full scale experiments of springing on board large tanker have been performed. Using these results, characteristics of springing have been examined. Expressions for combined stress are shown. Short-term and long-term distributions of springing stress are also presented. It is shown that the combined stress is less than the sum of wave bending and springing stresses. The extreme value for 20 years of springing stress of 237,000 dwt tanker is estimated about 4 kg/mm sq.
