Good warship design incorporates redundancy for critical systems. In general, this means at least two engines, fuel tanks, pumps, compressors, air tanks, etc. with capability for each to serve either (or all) of the others. This is frequently extended to port and starboard piping systems so fuel, air, and water can be pumped to or from reservoirs and trim tanks even when battle damage to one side of the ship breaks piping. Many tanks and pumps can handle different fluids (fuel or salt water or fresh water) in emergency circumstances. Each of these capabilities requires valves to isolate alternate systems from the system in use. In addition, after battle damage, each pipe through a water-tight bulkhead is a potential source of flooding, so it is good practice to put valves on either side of such bulkheads. =AL=
