... ABSTRACT An FPSO mooring line experienced a premature chain link fracture in the top section. The subsequent examination of the failed link identified that the fracture was caused by corrosion fatigue. The fatigue crack initiated at the bottom of a corrosion groove. The groove has a W-shaped...

... ABSTRACT: Frequently, water injection pipelines do not last their design life due to corrosion problems. More often than not, the reason has been ‘channelling’ or ‘grooving’ corrosion at the bottom of the carbon steel pipeline. Once this mechanism does manifest itself within a pipeline...

... of the spindle core, the interpretation of the bronze coated flanks could be generalized to all screws, independently on the coating material. The deep circumferential grooving on threads at the middle of the screw is the main indication of the abnormal flexion of the spindle (Figure 2). Any surface mark...
