    Abstract

    The theoretical background for the ship protection islands for the Great Belt suspension bridge in Denmark is presented. The islands protect two anchor blocks and five approach bridge piers of the Great Belt Suspension Bridge in Denmark. The design is a complex multi-discipline task. Besides protection of the bridge and of the grounding ships aspects like erosion of the islands and hydraulic resistance to the water flow through the belt must also be considered. The paper is focused on the design aspects related to ship grounding. It presents a theoretical model, which predicts the ship motions, the loads and the deformations during a ship grounding event on a soft sea bed. The models applied to determine the shapes of the artificial islands, which most efficiently protect the bridge from ship impact while posing minimum risk of damage to the grounding ships, requiring the least amount of building material and giving minimum resistance to the water flow through the belt.
