Offshore concrete structures are today designed using the best available techniques. These include predictions of the force resultants in the structure using FE analysis with up to 1.5 million degrees of freedom, code checking of FE results using special dedicated postprocessing software, local capacity evaluations in areas where the linear FE analysis is known to be inaccurate. Further, special analyses are carried out for prediction of response from earthquake, wave induced dynamic action and geometric non-linear action. This paper addresses the finite element modeling of a large offshore structure for verification purposes, based upon the experience gained with the Draugen GBS platform for A/S Norske Shell. The paper describes the philosophy for element selection, fineness in model, incorporation of built in stresses through the construction phases and the different load cases applied on the model. The paper further describes the post-processing of the results form the finite element analysis. This includes the accuracy of integration of stresses to obtain force resultants as basis for the general design, the accuracy of extrapolation of force resultants to critical cross-sections and the limitations in the code checking in general.
