Hunan University of science and technology led the research and development of China's first "Manau II" deep pressure coring drilling system with large hole in the South China Sea, successfully drilled 231 meters in the deep water of over 2000 meters, setting a new drilling depth of the world's deep-sea subsea drilling rig. The success of this deep-sea test fills in the gap of deep-sea drilling equipment with the function of pressure maintaining coring, which is more than 100 meters deep, and also marks that China has reached the world's leading level in this technical field.
