This is a study of the effects of cyclic loadings from storm waves on the axial capacity of piles driven in cohesive soils and supporting offshore platforms. The study developed an advanced analytical procedure to estimate pile penetrations and to evaluate the pile performance when a platform is subjected to intense cyclic loadings. The procedure is illustrated with application to a platform located in a water depth of 1.000 ft in the Gulf of Mexico. It was found that the limited numbers of cycles of intense design storm result in a significant strength degradation in the upper two-thrds of the pile length. The bottom one-third of the pile provides the margin of safety for loadings that could exceed those of the design storm. The details of the study are described, and the findings are discussed.
