ANALYSIS AND INTERPRETATION OF FULL-SCALE DATA ON MIDSHIP BENDING STRESSES OF DRY CARGO SHIPS.

Abstract

Results of the analysis of stress data from full-scale measurements on two C-4 type cargo vessels are presented in the form of histograms and cumulative distributions, which together with previously analyzed full-scale data cover a total of five years of normal ship operation in the North Atlantic. Two rational techniques are given for the extrapolation of full-scale data to longer periods of time, in order to predict extreme bending stresses (or bending moments) in service. Recommendations are made for more data collection from different ships on different routes, for investigation of other statistical techniques, and for development of methods for model predictions of long-term trends.
