This article describes the patented design for a floating "flush repair dock". In plan view, the design has a U-shaped working deck which encloses a lifting pontoon for ship docking. The ship enters through the open end of the "U", and the pontoon then rises using a system of tanks and pumps until its surface is flush with the working deck. The dock has no walls, but rather, with the pontoon raised, forms a large flat repair area. The pontoon stability with respect to the working deck during raising and lowering of vessels is maintained by a system of guide rolls and mooring winches placed between pontoon and working deck. The design shows capacity for vessels of 150,000 dwt, and the dock is to be fitted with two goliath cranes of 200 ton and 400 ton capacity respectively, which run on tracks along the outer edges of the working deck. Order from BSRA as No. 52,304.
