For decades, development of oil and gas projects on the Continental Shelf, offshore Trinidad, has involved geotechnical site investigations. A database from such investigations performed for one operator is presented for both static and dynamic soil engineering properties. Results are compared to other published databases for soils of the Gulf of Mexico and the Bay of Campeche. When coupled with site specific geological understanding and high-quality, cone penetration test data, the Trinidad database can reduce the need for collection of additional samples for similar testing for future projects in the area. Furthermore, the database can assist engineers in re-interpretation of old, low-quality geotechnical datasets used in re-assessments of ageing platforms.
