Bathoport (also a bootport , from French bateau-porte ) is a floating hydraulic lock , usually used to lock the entrance to the dock . To close the dock, the batoport is filled with water, while it sits on the bottom of the dock and presses with special protrusions to the ledges made along the contours of the batoport in the walls and bottom of the dock.
In a dry dock , as the dock is drained, the batoport more and more tightly presses its thresholds against the walls of the dock due to the difference in pressure on it outside and inside the dock and thereby blocks the access of water into the dock.
In wartime, the batoport is the most vulnerable element of the dock, since damage to the batoport results in the long-term failure of the dock [1] .
