Abstract

Many uncertainties are encountered in the evaluation of the stability of the foundations of gravity platforms. These include variability in the properties of the sea floor material and inaccuracies in the method used to determine the shear strength and in the analytical method. The important sources of uncertainty were identified for the site of Statfjord B. Published data, when available, were used to evaluate the magnitudes of the uncertainties, and subjective opinions were used when data were inadequate. A first-order, second-moment analysis was used to evaluate the effect of the uncertainties on the reliability of the foundations. Several criteria for the determination of the undrained shear strength were studied and the corresponding reliabilities were compared. The contributions of new information on undrained shear strength and cyclic shear strength to the reduction in uncertainty were evaluated.
