Ships (Cold-Iron Support). Potable water consumption
aboard ship varies according to climate, the number of personnel
on board, and the class of ship. Ship's characteristics database
(SHIPS) at http://www.efdlant.navfac.navy.mil/LANTOPS_15/home.htm and CCB contains
water consumption data for each class ship. If a particular ship
is not listed in this table, then a similar ship (size, form,
function) should be used as the best available data. Estimated
water consumption is calculated by multiplying the number of days
the ship received shore water by the ships potable water
requirement listed in the ship's characteristics database (SHIPS)
at http://www.efdlant.navfac.navy.mil/LANTOPS_15/home.htm.
