FRESH WATER SUPPLY ABOARD OCEAN-GOING MERCHANT SHIPS: THE ECONOMIC MERIT OF DISTILLATION FROM THE SEA

The average annual cost of obtaining fresh water for boiler feed and domestic use by distillation from the sea is calculated for two distinct types of merchant ship and compared to the cost of carrying purchased shore water for these uses. Results are presented as annual cost differences between the alternatives as functions of voyage length, with other significant factors as parameters. These results confirm the general belief that distillation is to be preferred, even if shore water did not typically require redistillation before use. Circumstances in which shore water might nonetheless be an attractive alternative are pointed out.
