The present invention provides a rapidly adjustable
nomogram slide rule for ship cabin flooding information and a method for using the same. The slide rule comprises: a
nomogram base plate for marking parameters related to damage and flooding; the
nomogram base plate has five parameter slots, namely, a slot for breach location and depth, a slot for cabin area, a slot for liquid level
rise rate, a slot for water inflow, and a slot for breach size; a stop bolt disposed on each parameter slot; and slotted slide bars disposed on the upper and lower sides of the nomogram base plate. The stop bolts pass through the upper slotted slide bar, the parameter slot, and the lower slotted slide bar, respectively. The stop bolts are provided with locking devices for locking the upper and lower slotted slide bars to the nomogram base plate. The present invention can calculate cabin flooding and submersion time, as well as breach size using a known water
inflow rate. Other parameters can be obtained using the slide rule based on any two parameters, facilitating
damage control personnel to quickly complete ship cabin damage and flooding calculations and implement anti-sinking decisions.
