Deep sea mining represents one of humanity’s most ambitious technological frontiers, targeting mineral resources at ocean depths that would have been unimaginable just decades ago. The International Seabed Authority (ISA) has granted 31 exploration licenses as of 2024, including 19 for polymetallic nodules primarily in the Clarion-Clipperton Zone (CCZ) of the Pacific Ocean, where deposits lie at depths of 4,000 to 6,000 meters below the surface [1][2]. These nodules contain economically critical metals including copper, nickel, cobalt, and manganese, with the CCZ alone estimated to hold over 21 billion metric tons of nodules. 深海采矿系统由生产支持船、深海集矿机器人、提升管道系统和最关键的脐带电缆组成。Deep sea mining systems consist of production support vessels (PSVs), subsea collector vehicles, riser and lift systems (RALS), and most critically, umbilical power cables that must transmit electrical power, control signals, and data communications across vertical distances exceeding 5,000 meters. The Chinese submersible Striver reached the Mariana Trench at 10,909 meters depth in 2020, demonstrating that engineering solutions for ultra-deep operations are technologically feasible, though commercially scaled mining operations remain in the exploratory phase [3][4].
