Enhancing the Life Cycle of the Jack up Structure by Applying Alternative Foundation Methodologies in Geotechnical Engineering

A jack-up structure is a bottom-mounted floating unit having an adjustable hull and movable legs. Particular structures are more susceptible to hazards under environmental loads during their operation life cycle in the ocean. Authors' attempts here enhance its sustainability shallow deep waters by correctly accessing soil behaviour predicting load carrying capacity. Here numerical analysis of substructure has been attempted. Simulation load-deformation behavior axial compression carried out for advancing research.
