Abstract

Mobile drilling platforms perform the majority of the world's drilling in water depths up to approximately 120 m. The installation of their large, inverted, conical spudcan footings into fine-grained silt material is considered problematic by an industry that has usually defined the conditions of installation as either undrained in 'clays' or drained in 'sands'. This is reflected in current SNAME industry guidelines. Little guidance is provided for calculating the penetration resistance of spudcans in partially drained conditions. The use of full flow-round penetrometers may provide the opportunity to directly correlate spudcan predictions with in situ measurements. Previous centrifuge testi..
