On October 3, manned deep sea test team of 112 members from 19 enterprises and institutes led by Deep Sea Science and Engineering Research Institute of Chinese Academy of Sciences returned to Sanya Port after completing all sea tests of China-made Submersible Shen Hai Yong Shi.
Submersible Shen Hai Yong Shi is an important research and development project under Plan No. 863 of China’s Twelfth Five-year Plan”. In developing Submersible Shen Hai Yong Shi the research and development teams of 94 domestic entities led by Research Institute No. 702 of CSIC kept on working hard to make breakthroughs for 8 years on the basis of the research, development and application of Submersible Jiaolong. Through their efforts, China has improved its capabilities of independent creation with respect to the core technology and key components and parts for manned deep sea submersion. It has thus lowered the operation and maintenance costs and vigorously boosted the construction of families of deep sea equipment with various set functions.

SCMP says in its report “China’s deep-sea mission to mine the wealth beneath the ocean floor” on October 10, China is stepping up its activities in exploration of minerals deep at the bottom of Indian and Pacific oceans.
It says that according to Tao Chunhui, one of the country’s leading oceanographers and a researcher at the State Oceanic Administration, there are vast sulphide deposits on 3,000 meter deep seabed containing copper, zinc and precious metals gold and silver. China is conducting exploration to know where the minerals are while developing the techniques to mine the minerals.
China has developed its manned Jiaolong submersible able to go to the depth of 7,000 meters and is now developing an 11,000-meter submersible to challenge the depth of of the Mariana Trench near Guam.
SCMP quotes Tao as saying,“China has made huge progress in deep-sea technology. We went from importing and copying to making our own innovations.”
