Abstract
This research and development project is aimed at development of the techniques which allow exploitation of manganese nodules occurring on deep sea bottoms (4,000 to 6,000 m deep) on a commercial scale, in order to secure stable supply of the non-ferrous metallic resource and improve general ocean development techniques. This project, established by the national project system, has been implemented cooperatively by the government, academic and industrial circles since 1981. Described herein are the interim results obtained by the FY 1984. The bases for development of the elementary techniques have been established for the comprehensive ocean tests. Bright prospects have been obtained to achieve the objectives, although there are some problems remaining to be solved. Interfaces between the sub-systems are being reviewed mainly by the persons in charge of the total system. No problem is foreseen in consistency of the individual components. The movement and exploitation functions of the test system are simulated and validated in detail, to develop the total system. It has been found by the simulations that the nodule-collecting machine shows nonlinear tracking characteristics (i.e., movement different from that of the exploitation ship), and unsteady movements (i.e., repeated movements of rapid starting and stopping).
