This paper presents partial results of two series of centrifuge tests that were performed on suction anchors. The first series addressed the specific conditions of the Mad Dog Cluster 2 anchors on the Sigsbee Escarpment (Berger et al 2006, Jeanjean et al 2006, and Schroeder et al 2006). Tests were performed for soil conditions, anchor geometry, attachment points, and loading angles closely matching the Mad Dog design parameters. The results provided a means of calibrating and validating the design method and failure mechanisms. The second series of tests was performed on double-wall anchors and allowed the separation of the three components of capacity: outside friction, inside friction, and reverse end bearing. Results gave insights into the failure mechanism of vertically loaded anchors and suggest that the traditional procedures for determining outside skin friction appear to be conservative.
