China's manned submersible touches record depths


BEIJING (PTI): A China-made manned submersible vessel designed to dive to a depth of 7,000 meters has successfully completed trial operations and reached over 3,700 metres, making it the fifth country in the world to develop such a technology.

The submersible, dubbed "Jiaolong", completed 17 dives in the South China Sea from May 31 to July 18, with the deepest reaching 3,759 meters.

The feat makes China the fifth country, following the United States, France, Russia and Japan, to have the technologies for a manned dive to more than 3,500 meters below sea level, the Ministry of Science and Technology and the State Oceanic Administration (SOA) said.

Three crew members were onboard in the dives, SOA said in a report.

"We went through strict selection and training procedures before we managed to get on board the submersible,"

Ye Cong, one of the crew on board told Xinhua news agency.

"The submersible is very convenient to manoeuvre and we operated it quite well under the water," he said.

"I think we've only achieved initial success in the test. The future application of the vessel will be more remarkable than this test," he said.

It also set a record by operating underwater for nine hours and three minutes, the SOA report said.

The average ocean depth is 3,682 meters below sea level.

A submersible differs from a submarine as it typically depends on another vessel or facility for support.

"As the first manned vehicle designed to reach 7,000 meters below sea level in the world, the submersible can be used in 99.8 per cent of the world's sea areas," said chief designer, Xu Qinan.

"It represents the most advanced technology in deep-sea exploration," he said.

So far, manned submersibles could only descend to 6,500 meters below sea level.

"Each part of the submersible has passed the pressure test of 7,000 meters, and their performance will be tested again in the future as we'll carry out 5,000-meter and 7,000-meter tests," Xu said.

China began to work on the ambitious ocean exploration programme in 2002. About 100 research institutes and companies were involved in the project.

The vessel would be equipped for deep-sea natural resources inspections, as well as research and tests of equipment designed for deep-sea use, the SOA said.
