    A fatigue analysis procedure was developed to evaluate the structural integrity of a drilling tower welded to an offshore platform. This weld is critical for fatigue and the knowledge of the probability distribution of the stress cycles on this critical point of the structure is necessary to estimate its fatigue life. The stresses on this point are given by the dynamics of the tower and the excitation of the tower is given by the dynamics of the platform (base excitation) which in turn is given by the wave loads.
