EXTRACTION FORCES FOR OFFSHORE FOUNDATIONS UNDER UNDRAINED LOADING

An experimental study is reported which used centrifuge modelng techniques to assess the large penetration installation behavior of individual jack-up spud cans in simulated uniform and stratified seabeds. Certain of the experiments invloved removal of the spud cans. The results of these experiments, which contribute to the understanding of certain aspects of the removal of jack-up spud cans and other shallow-depth, gravity based structures, are discussed. It was found that performance of simulated jack-up foundations subjected to uplift associated with removal from the seabed depends upon the previous compressive load history, and associated penetration ratio. These and other study results are discussed.
