The paper presents models and results of the structural strength analysis of a roofed floating dock. Computed thickness of the roof structure walls capable of withstanding the environmental loads is 24 mm. Heavy sliding roof segments generate the dock pontoon floor plate stresses reaching 25% of the permissible stress value. The dock pontoon structure effort under the roof and docked ship weight load was minimized by seeking an optimum balancing ballast distribution. The problem was solved in two ways: analytically, by means of a simplified model of a continuous beam on elastic foundation and numerically, using the linear programming method to construct an accurate discrete FEM model.
