It is these docks that the major repairs are performed on many of the ships of the Navy. The entrance closure is an integral part of a basin typedock, and the two factors governing its design are mobility and strength. It must be mobile to allow easy handling in clearing a channel for the ships to be floated in and out of the dock. Yet at the same tine it must hare sufficient strength to withstand the hydrostatic pressure of the water on the harbor side of the gate after the interior of the dock has been pumped dry. Of the several types that have proven satisfactory, the United States Navy favors the floating type of dry dock closure.
