In steel offshore platforms used for drilling and production of oil and gas, failures of structural steel members can occur due to pitting corrosion and corrosion fatigue at welded nodes where the brace members are joined. These nodes are areas of high stress concentration due to the complex geometry of these locations. The purpose of this paper is the application of FEM structural analysis to a model of K-T joints of a jack-up rig leg to explore the effect of random pitting corrosion on its strength capacity. The results are presented along with those previously published for the same model for the case of uniform corrosion.
