Studies of wave-induced vibrations (springing) have been carried out, both theoretically and experimentally, by many researchers over a number of years and numerous references to their work are given at the end of the present paper; in this paper the Authors describe model experiments carried out using a 7-m long tanker model and compare the results with theoretical calculations and full-scale tests. Using the results of the tests, the characteristics of springing were examined. Expressions for combined stress are given and short-term and long-term distributions of springing stress are presented. It was shown that the combined stress is less than the sum of wave bending and springing stresses. The extreme value of springing stress over a period of 20 years for a 237,000-dwt tanker was estimated to be about 4 kg/mm square. Order from BSRA as No. 54,545.
