Session: Foundations V / Fondations V

ABSTRACT: Part of the proposed transition of the German energy market to renewable energy will be based on the large-scale development of offshore wind farms. Due to large pile diameters and distinct cyclic loading effects from wind and waves, new challenges arise for the pile design of the foundations. This contribution gives an overview of the specific cyclic pile design aspects with a focus on offshore wind farm installations in the German sector of the North Sea. Three methods are presented: An interaction diagram, an analytical and a numerical approach.

RÉSUMÉ: Une part de la transition proposée, du marché allemand, développement à grande échelle de parcs éoliens en mer. En raison du grand diamètre des pieux, ainsi que des actions cycliques résultantes du vent et des vagues, de nouveaux défis sont apparus quant au dimensionnement des pieux de du Nord. Trois
