Design of a 93-m diam x 90-m tall oil storage tank and production platform for the Norwegian North Sea required an investigation of the stability of the dense sand foundation against liquefaction from the wave induced cyclic loads on the structure. The results of special cyclic loading triaxial tests, interpretated in terms of the expected maximum storm conditions, demonstrated the adequacy of the foundation and illustrated a number of new aspects concerning the liquefaction potential of sand under cyclic loading.
