Abstract
One of the offshore structures which may be categorized as a column structure where the axial compression and lateral pressure take place is jack-up. The internal and external loads make the structure becomes deformable, leading to failure. For this reason, the structure must be analyzed for the internal and external response. In the present study, the structural response analysis of the jack-up structure during the system jacking lifting process is conducted using a nonlinear finite element method for three cases of the conditions to be analyzed for the structural response. The result obtained by nonlinear finite element is presented in terms of stress and deformation.
