Necessity to design and build a ship for winning Fe-Mn concretions from sea bed, and put it into operation, results mainly from decreasing land resources of mineral rough materials and increasing prices of metals. Main dimensions and parameters of such mining ship were determined by elaborating its main design assumptions and making use of suitable data on drilling ships considered similar from the point of view of attributed functions and spatial arrangement. In this paper a design study on preliminary concept of dimensions and spatial arrangement of a ship for winning poly-metallic concretions from sea bed, is presented. The study has been aimed at elaboration of an appropriate mathematical model to be applied for optimization of ship’s winning system.
