Tubular joints are widely used in offshore structures and are prone to fatigue due to the high stress concentration. The fatigue life may be significantly reduced after the corrosion protection fails for tubular joints in a corrosive environment. The study uses the finite element method to investigate the effect of uniform and grooving corrosion on hot-spot stresses of a T-shaped tubular joint. The weld geometry is considered in the model, and the grooving corrosion is modelled, assuming that the corrosion rate of weld metal is 1.4 times that of the base metal. The results show that the Stress Concentration Factors (SCFs) increase with the corrosion depth for the cases of uniform corrosion. At the same time, the SCFs decrease with the increase of the corrosion depth for the instances of grooving corrosion. The complex stress distribution around the grooving corrosion area may invalidate the surface extrapolation method for determining hot-spot stresses.
