Effect of foundation behaviour on steel jacket offshore platform failure modes under wave loading

In this paper, the performance and failure modes of a newly designed platform have been studied numerically as a case study. In order to investigate the effects of soil condition on the behaviour and failure modes of the platform, two different soil profiles named SC1 and SC2 classified as weak and strong soils, respectively, have been investigated. Static Pushover analysis has been performed by considering wave loading as the lateral load pattern exerted on the platform. Different models in terms of different soil types and different pile sizing have been developed. A comprehensive discussion has been presented about the effect of these parameters on the modes of failure of the platform. Analysis results revealed that the strength proportionality between the foundation and the jacket part of the platform leads to a better performance of the platform in accordance with high indeterminacy of the jacket structure and helps prevent immature failure.
