Detailed experimental investigations have been taken up to study the corrosion fatigue behavior of steel tubular joints used in offshore structures under constant amplitude and random loading with respect to tropical seawater environment for which there is lack of data. As part of this study, corrosion fatigue tests were conducted on two unstiffened and nine internally ring stiffened welded steel tubular T and Y joints under constant amplitude axial brace loading at 0.2 Hz frequency. Seawater characteristics, corrosion rate an fatigue crack initiation and propagation were monitored during the tests. Hot spot stress range and stress ratio were varied for the specimens. The results of the study are discussed in this paper.
