China's self-developed submarine 60- meter multi-purpose drilling rig "Maniau" carried out a sea trial in the deep sea of ​​the South China Sea and achieved success. For the first time, the sea trial achieved 60- meter drilling of the seabed in the deep seabed with a depth of more than 3,000 meters , marking China's ability to sample deep-sea seabed. China has become the fourth country to master this technology after the United States, Germany and Australia.
In the field of development of deep-sea drilling rig, it is 50 meters Dao Kaner. Which country has more than 50 meters deep-sea drilling depth of the equipment, we have advanced deep-sea drilling ability, exploration of seabed mineral resources to a greater depth. More to the point, in accordance with the provisions of the United Nations, who has the capacity to follow the high seas mineral resources exploration first, whoever has the priority right to develop the rules. Successful sea trial "manatee" was to enhance the technical advantages of the development of mineral resources in the high seas.
"Seabed 60 meters multi-purpose technology development and application of drill system," the State "863" project of marine technology, developed by Hunan University of Science and Technology, Chinese Academy of Sciences and the Institute of Oceanology, Guangzhou Marine Geological Survey Bureau jointly, main scientific task of Hunan University of Science and Technology bear. On May 22nd , the “Maniuu†carried out the sea test for the first time in Xiamen offshore, and realized the test of decentralization and bottoming of the offshore drilling rig, leveling of the attitude, in-situ detection of the seabed, and recovery of the rig. The communication and control systems were operating normally. test data indicators to achieve the desired effect.
The sea trial mainly includes the seabed 60m multi-purpose drilling rig body, submarine in-situ detector, deck control and distribution system, mobile subsea drilling rig supporting and retracting system, and supporting mother ship. In the sea trial, the "Manatee" was drilled for 10 hours on a 3,000- meter-deep seabed with a depth of 60 meters.
