Abstract

This paper presents the methodology for construction of the most suitable system for the deep sea manganese nodule mining. The system consists of Miner, Mining Ship, Transportation Ship and Metallurgical Processing Factory. As the objective function, the period of the revulsion of capital is chosen. The reliability of the results is investigated by varying the costs of operation, the ship prices and metal prices. The optimum system for the mining and transportation is obtained, which the system includes the effect of ship motion in waves on the operation days. The period of the revulsion is mostly affected by the price of manganese nodule and the acceleration of ships.
