Nonlinear Finite Element Analysis of the Stability of Gravity Platform

Abstract:

Gravity platform was widely used in the development of marginal oil field, but the existence of scour pit caused by the flow and wave increasing the possibility to overturn. The paper introduced the no depth contact interface element to simulate the nonlinear effect between the bucket skirt and soil, and introduced the birth-death element to simulate the increasing scour pit. The results provide guidance to prevent overturning.
