Mother ship for new submersible put into service in S China

The mother ship for China’s new deep-sea submersible arrived in the southern Chinese port of Sanya on Tuesday.

The 94-meter “Tansuo-1” was delivered to its owner, the Chinese Academy of Sciences, or CAS, a day earlier.

It has a full-load displacement of 6,250 tonnes, and has an range of 10,000 nautical miles.

It’s equipped with 10 permanent research labs and two removable labs.

The ship will serve as the mother ship for a new submersible currently under development and for future CAS expeditions of sea floor trenches.

It will conduct off-shore tests in waters near Sanya.

If all goes well, the ship will sail on to the Mariana Trench in June for a research mission.

The new manned submersible that can reach a depth of 4,500 meters is likely to go through off-shore testing in the first half of next year.

China’s current manned submersible “Jiaolong” reached a depth of 7,062 meters in the Mariana Trench in June 2012.
