Abstract

Fatigue crack growth tests have been performed on specimens extracted from S355 welded plates to characterise the crack growth behaviour in monopile welded structures in air and seawater. All tests were performed under the load ratio of R = 0.1 and maximum load of Pmax = 10kN. The obtained data from these tests have been compared with the fatigue crack growth trends recommended by BS7910 for welded joints. In addition, the corrosion damage effects on the crack growth behaviour of the material have been examined. The test data obtained from this study have shown that the BS7910 simplified Paris-law trend provides an acceptable estimate of the fatigue crack growth behaviour in the weld metal.
