Hurricane Roxanne is marked in the history of Bay of Campeche as one of the most severe storms that hit the zone during this century, and therefore questioned the validity of the design criteria applied at that time. As a consequence, a newborn own risk based criteria was developed for design and assessment of submarine pipelines and platforms in Bay of Campeche. Petróleos Mexicanos (PEMEX) and Instituto Mexicano del Petróleo (IMP) developed and issued such criteria in 1998, named Offshore Pipeline Transitory Criteria. The Transitory Criteria is based on risk assessment and management approach.

It is intended in this paper to show the result obtained so far of that development. Safety and serviceability categories for pipelines are defined. Safety factors for design and reassessment of wall thickness by internal pressure are determined based on risk approach. Practice recommendations for the design and requalification for hydrodynamic stability of submarine pipelines and risers are established. Safety factors for hydrodynamic stability are obtained following this criteria, and oceanographic characterization of the Bay of Campeche are presented in easy-reading charts for design and requalification.
