Radiant Cooling for Closed-Loop Water Containment: Exploration of Possible Application in Dry Docks

Abstract

Models based on empirical fluid flow and heat transfer data combined with basic principle analysis provide data for estimating the cost of implementing a closed-loop radiant cooling system for ships in dry docks. Depending of the material used, pipe lengths from 300m to 3000m with diameters ranging from 10in to 24in all cooled a design load of 8 F degrees =4.bar(44) K above ambient temperature when that temperature was assumed to be 300 K. From the cost analysis performed, $12 million would be the maximum initial investment for the system that moves 26 million gallons per day (approximately 18000gpm). This leaves $30 million to pay for the other aspects of implementing this system.
