초록
심해 망간각이나 열수광상 등 해저광물자원을 개발하기 위한 과정의 일환으로 수심 1,000 m 해역에서심해광물의 예비양광시험(pilot lifting test, PLT)이 계획될 수 있다. 본 연구에서는 PLT 수행을 위해 필요한시험선과 핸들링 장비, 양광관, 공급관, 양광펌프, 동력장치 등 양광시스템 선정과정에서 고려하여야 할 요소와제어계측 장비 등에 대한 설계요소를 제시하였다. 또한 시험선 운영 및 양광시험을 위한 시험선 이동, 장비의선적, 배열 및 설치, 양광관, 양광펌프, 수중탱크 등 수중 장비의 배열 및 회수 방안, PLT 전과정에 대한 계획을제안하였다. 본 연구결과는 향후 심해저 양광시험 수행시 유용한 지침으로 활용될 수 있을 것이다.
Abstract
A pilot lifting test(PLT) at a 1,000 m deep sea can be planned as the middle stage of developing the mining technology of the deep-sea mineral resources such as manganese pavement and seafloor hydrothermal deposit. In this paper, the fundamental factors including the test ship and the lifting system comprized of handling equipment, lifting and supply pipes, lifting pump, buffer tank, and power system required for the PLT, have been investigated. And the basic design of the control and monitoring for PLT has been suggested. The operation and the mob and demob of a test-ship, the shipping, installation, interface and unload of the equipments, the deployment and recovery of the underwater equipments such as lifting pipes, lifting pump, and tank, as well as the overall procedures of PLT have been considered and presented. The results of this study can be used as a useful guide of the deep-sea mineral lifting test in the next stage of the development.
