Criteria for design and requalification of platforms in the Bay of Campeche, Mexico

Risk assessment and management based hurricane and earthquake criteria have been developed for design and requalification of Petroleos Mexicano platfo rms in the Bay of Campeche. Results from recent field tests were used to ve rify the loading and capacity analytical models and to characterize the bia ses and uncertainties in these models. American Petroleum Institute wind an d wave loading and earthquake response spectra-based procedures were used t o determine the loadings associated with extreme condition hurricanes and e arthquakes. Assessment of the platform capacities included recognition of t he time-dependent loading and nonlinear platform capacity characteristics. The platform element capacities were based on current American Petroleum In stitute working stress design and load and resistance factor design procedu res. Design and requalification criteria to evaluate the platform system re serve strength ratios that resulted from the application of the risk assess ment and management are summarized in this paper. Working stress design and LRFD parameters are not detailed in this paper due to paper length limitat ions.
