78997 - Development of a Response Assessment Tool for a Floating Dock System 

Docking operations of ships require the response assessment to ensure structural and personnel safety. Environmental loads and improper ballast adjustments are the main threats to the docking operations. They can cause severe structural damages and stability loss to a floating dock system which includes a floating dock and a docked vessel, even if the velocities of the dock and the vessel are very low during the docking process. Safe docking operations need to perform a reliable assessment of the floating dock system’s responses, i.e., structural strength and stability. This paper aims to provide a framework of a floating dock system’s response assessment. The stages of ship docking operations are described. The environmental and operational risks involved in those stages are analysed in detail. Then we critically review various studies on the structural strength assessment and stability analysis of floating docks. Further, we propose a framework to perform a response assessment of a floating dock system. Finally, the framework of floating dock system response assessment is provided. The language Modelica is used. Various external and internal loads concerned in dynamic modelling have been highlighted. The case studies of a single dock dynamic analysis are discussed. Future work on the development of the response assessment tool is also shown.
