This paper gives a brief overview on the major milestones of the deep sea mining projects in the 70's and 80's with focus on the OMI/OMCO-Consortia and the engineering milestones SEDCO 445, Hughes Glomar Explorer, Clementine II and PLA2 6000, the pilot mining tests of the AMR, the environmental study DISCOL and the joint efforts of Gemenod/Preussag. Among the most interesting and technologically challenging systems are those for deep sea mining of manganese nodules in water depths of 4,000 to 6,000 meters in the Mid-Pacific. Following the total integrated systems (TIS) approach, the technology transfer between ultra-deep water drilling and deep sea mining is outlined based on several subsystems and specified for the key components of the vertical transport system. As example for state of the art engineering and technologies recent developments of heavy-load active heave compensated drawworks, ultra-deep water riser systems, motion-compensated offshore mining drill pipes with air-lift slurry transport, remote subsea workclass-crawler ISUP and the Korean manganese nodules collector MineRo II are described. Based on the principles applied for development and engineering of systems for shallow water offshore mining and the experiences available from the pilot mining tests conducted in the past, a concept for an offshore mining system was developed by MHWirth in corporation with the German Federal Institute for Geosciences and Natural Resources (BGR). This concept will be outlined in the current paper together with the main results of an economic feasibility study. Furthermore, an overview on the current European deep sea mining research projects and a renewed German-French industrial cooperation is given. Synergies with the emerging private space industry are anticipated regarding systems engineering. Future perspectives for a new pilot mining test are discussed.
