This paper summarizes the application of the PEP/IMP Transitory Criteria for the assessment of fixed offshore platforms located in the Bay of Campeche, Mexico. Comparisons of the Transitory Criteria with the Section 17 of API-RP2A, 20th edition are made, utilizing two sets of metocean data. Design level analysis and ultimate strength analysis results and comparisons are presented, which included the application of the Load Reduction Factors (LRF's) and calculation of the Reserve Strength Ratios (RSR's). Also, seismic assessment procedures, results and comparisons are summarized. The results of the analyses using metocean and seismic loadings were used to determine the fitness-for-purpose adequacy of 14 PEMEX platforms located in the Southwest Marine Region of the Bay of Campeche.
