COMPARISON OF TREATMENTS OF NON-LINEAR DRAG FORCES ACTING ON FIXED OFFSHORE PLATFORMS

An analysis of the hydrodynamic responses of a fixed offshore platform is performed using a single-degree of freedom system model. Solutions are obtained using three different forms of representing the drag forces, non-linear and coupled to the structural responses, non-linear and Uncoupled, and the standard linearized form. For a harmonic sea state a solution of the non-linear coupled case was obtained through a step-by-step integration procedure. Response time histories were also obtained for a simulated random sea state.
