Vessels with hydrodynamic ducts with flow management mounted on their bow with horizontal wall sections with surface wave management

摘要

A vessel equipped with a hydrodynamic duct with flow management at the bow, the hydrodynamic duct comprising: horizontal wall sections (2) extending on each side of the centerline (CL) of the bow of the vessel (8); at least one additional horizontal wall section (1) designed to manage surface undulations and positioned above the horizontal wall section (2) in the region of the waterline; and a pair of side surfaces connected to each end of the horizontal wall parts 1 and 2 and extending upward from each side of the bow, thereby forming in association with the horizontal wall parts 1 and 2 The duct, which is circumferentially closed, by directional wall sections (5); the flow inside it is totally differentiated from the flow outside the duct, this differentiation being depleted for the reduction of wave resistances and the navigation of the vessel. This results in a reduction in the fuel used and the required rated horsepower. one additional horizontal wall section 3 , or two wall sections 3 , 4 between the horizontal wall sections 1 , 2 complementarily or in the loaded and unshipped condition of the ship Variations have been proposed to work alternatively.
