A reference jacket support structure to be adapted for different water depths is developed. These constraints result in extensive temporary steel and earth platforms for facilitating the foundation construction and the excavation and lateral support works with a complex construction sequence. As structures reach their design service lives, the fatigue life should be reassessed. Then, a static and a dynamic fatigue analysis for the offshore jacket-type structure under consideration are evaluated and compared.
