Abstract: The results of a pilot study investigating correlations between index tests and soil design parameters are presented for offshore clays are presented. An important objective of the study is to develop a database consisting of high quality laboratory data from tests conducted in a consistent manner. The database includes ten sites from locations in the Atlantic Ocean, the North Sea, the Norwegian Sea, the Caspian Sea and two onshore sites. Analysis of the database shows that there exists a better correlation between preconsolidation stress and liquidity index but with considerable scatter as the liquidity index decrease below 0.5. A strong linear relationships between preconsolidation stress and undrained shear strength for triaxial compression, triaxial extension, and direct simple shear test are also found. Recommendations are given for use of these relationships together with the preconsolidation stress-liquidity index correlation for estimation of in situ undrained shear strength.

Key words: offshore clay, design parameters, index properties, preconsolidation pressure, undrained shear stress, correlations
