Design of a Flexible Hoses of Lifting System in Deep Sea Mineral Resources

Abstract

The flexible hose, connected from the buffer system to the collector, is a kind of transfer pipe and plays a role of transferring mineral resources with seawater from the collector in deep sea lifting system. The flexible hose should be designed to consider various complex factors such as environmental condition, risk assessment, function, and operation. This study discussed the constituting facilities, dangerousness evaluation factors, function, materials, operation, deployment and retrievement related to flexible hose essentially.
