In this article are described the damage assessment and rehabilitation of the Ciudad Pemex-La Isla 24-inch sour gas pipeline managed and operated by Pemex (Petroleos Mexicanos SA). The assessment of the pipeline derived from data on the pipeline's defects gathered with MFL (magnetic flux leakage) ILI (in-line inspection) devices ('pigs') and field external nondestruction measurements. Assessment of the reduction in safety from mechanical and weld defects proceeded according to fitness-for-service procedures compiled in API Recommended Practice 579. Corrosion defects were assessed with deterministic approaches given in the modified ASME B31G code as well as through structural reliability studies. Risk analysis also established a priority scheme for the rehabilitation program.
