In several types of vessels, including those in the dredging fleet, corrosion-erosion failure is common in the sea water loop of the power plant cooling systems during operations in polluted water areas. To prevent clogging and wear and a negative impact on the ecology from the intake of fish eggs, fry and other bioorganisms, it would therefore be desirable to minimize the intake of sea water for the cooling system. The problem was dealt with when designing a 500-ton floating crane, and the system developed is described. It involves use of a marine shell heat exchanger that enables creation of a closed one-loop cooling system that eliminates the sea water loop and improves equipment operating reliability. Calculations and actual test data were found to converge, making it possible to recommend use of the results in designing closed-loop systems for floating cranes, floating drilling rigs, and other craft and vessels.
