摘要：	A prototype deep-seabed mining robot that had become uncoupled from a cable connecting it to a surface vessel has been successfully recovered from the floor of the Pacific Ocean. Patania Ⅱ - GSR's purpose-built prototype nodule collector - is currently being trialled in 4,500 m water depth in the Clarion Clipperton Zone (CCZ) of the Pacific Ocean. On its final dive in the GSR area on 25 April, a lifting point separated and Patania Ⅱ was uncoupled from the 5 km cable that connects it to the surface vessel. Following a survey by a remotely operated underwater vehicle a recovery mission was undertaken and successfully completed on 29th April. "We are taking a cautious, step-by-step approach to project development. We conduct these trials to better understand the challenges involved so we can continuously refine our technology." said Kris Van Nijen, Managing Director of GSR. "The prototype has functioned well, and learnings will be taken into the next phase of development. This is pioneering engineering work and we were prepared for multiple eventualities. Today we were able to reconnect Patania Ⅱ and we look forward to completing the mission, including further deployments of Patania Ⅱ." Prior to this incident Patania Ⅱ had successfully demonstrated its ability to drive and maneuver on the deep seabed and collect polymetallic nodules. Independent monitoring of the trial by scientists from 29 European institutes was also successfully completed.
