Performance Analysis of Deepsea Manganese Nodule Test Miner in Inshore Tests

Abstract

: Inshore tests were performed in order to verify the design concept of deep sea manganese nodule miner at a site near Hupo at East Sea of Korea in June of 2009. Total mining tests of the test miner, named 'Minero ® ', together with flexible hose, lifting pump and lifting hose were accomplished. In this study, the performances of three subsystems of testminer (vehicle, pick-up device, and launch-and-recovery device) were analyzed for feasibility assessment of self-propelled remotely controlled miner, and also to compile basic data for designing a pilotminer. Performances of the test miner were defined based on the Functional Requirements of Axiomatic Design. The inshore tests revealed that the test miner generally satisfies the functional performances. Feasibility assessment and reflection on results are discussed within.
