Consumable Capacity and Price of Deep Ocean Water

Abstract

Consumable capacity and price of deep ocean water (DOW) were investigated on the assumption that the demand of the deep ocean water significantly increases in all over the world. In the first part of this paper, the limiting rate of upwelling DOW to the total flux of s ource water, which is assumed to be 3.3 % of the total flux, was determined on the basis of a natural fluctuation. The consumable capacities of DOW for several application sites were individually obtained using this limiting rate. In the second part of this paper, an economic a nalysis of a DOW distribution system, which consists of a floating-type upwelling system, three land-based storage systems and several shuttle tankers, was carried out. The results showed that the obtained break-even point price of the DOW is reasonable in comparisonw with the price of the public service water.
