Abstract

Five different specimens representing different typical welded connections in ship-shaped structures were fatigue-tested by HHI in Korea. The test data from the five different specimens for one loading condition were transferred into one hot spot S-N diagram. It was observed that two of the data series plotted rather high in the S-N diagram as compared with the other three test series. The reason for this was questioned. It was decided to test a few specimens at another test laboratory for verification of the test data. The same types of specimens were fabricated by HHI and shipped to Oslo and fatigue-tested in the laboratories of DNV. The results from this fatigue testing are presented in this paper in addition to the original fatigue test data from HHI.
