Hydrodynamic Responses of Modular Hybrid Piers (MHP) to Passing Ships

摘要

This study explores the passing ship effects on a floating pier in typical navy waterfront environments. The goal is to observe the pier performance in the passing ship episode, identify disturbances due to the buoyancy hull of the pier to the ambient water and client ships, and assure the design capacity of the founding system for the pier. The study addresses relevant hydrodynamics with a proven simulation model replicating the hydraulic model test procedure. The results indicate that the buoyancy hull of the pier does not substantially disturb the ambient water activities. Passing ships hardly move the floating pier nor contest the design capacity of its founding system. For example, the maximum load on an individual founding shaft in the worst case passing ship scenario varies from about 8 to 40 percent of the design capacity of the fenders around the founding shaft. The variations depend primarily on the number of client ships and their layout at the pier.
