Stress and deformation analysis of a modular floating dock with a 5000-ton lifting capacity

Abstract

This study investigates the global structural behaviour of a modular floating dock with a 5000-ton lifting capacity. Using the finite element method (FEM), the research assesses stress and deformation responses under different operational conditions, namely-lightship, ballasted, and full-load, both in calm water and under wave loads. Identifying the vessel’s critical stress concentration zones, the study effectively evaluates these areas, providing targeted recommendations to optimize the vessel’s structure and improve its operational reliability.
