Most of the components of marine and offshore structures are subjected to cyclic loading during their service time due to action of seawater waves and the sea environment in general. Fatigue failures in these structures can take place at sites of high stress concentraction that can be classified into two major categories, that is, base material and weld jaints. However, tt is well known that a considerable amount of scatter is showen in experimental results relating to fatigue crack growth even under identical and constant amplitude cyclic loading conditions. And also, it is well known that the Flux Cored Arc Welding(FCAW) is a common practice to join the thick plate such as structural members of large scale offshore structures and very larger container ships. The objective of this study is to investigate the variability of fatigae crack growth arte (FCGR) for the FCAWed API 2W Gr. 50 steel weldment typically applied for offshore structures. In order to investigate clearly the variability of fatigue crack growth rate for the materials of three different zones WM, HAZ and BM, experimental fatigue crack growth tests for each five specimens were performed on ASTM standard compact tension (CT) specimens under constant amplitude cyclic loading. It was showen that the variability of FCGR for WM specimen was higher then those of HAZ and BM, espacially in low driving force regio, and the probability distribution of FCGR was followed well Weibull distribution.
