One of the most important soil parameters required in the analyses of the piles of oil platforms subjected to lateral earthquake loading is the shear wave velocity (V S ) of the soil. Since in-situ measurements of V S is part of the scope of work of a limited amount of platform sites, there is the need to develop site specific correlations to estimate V S based on basic soil properties. To cover this need a database with in-situ measurements of V s and basic soil properties of clay has been established. Data were collected from eleven offshore geotechnical investigations performed on behalf of PEMEX for the design and installation of fixed offshore platforms in the Bay of Campeche. The database was tailored to developed empirical correlations between the shear wave velocity and undrained shear strength, effective vertical stress, water content, void ratio, overconsolidation ratio and net cone resistance, using simple regression analyses and multiple regression analyses. Three of the most prominent empirical correlations developed using multiple regression analyses are recommended to provide a mean of determining the best estimate V S in clay, along with a three step procedure to perform site response analyses in the Bay of Campeche when in-situ measurements of V S at a site are not available.
