BEIJING -- China's new underwater remotely operated vehicle (ROV), one of the world's most powerful ROVs, rolled off the production line in Shanghai, Science and Technology Daily reported Wednesday.

The subsea equipment, produced by Zhuzhou CRRC Times Electric Co., Ltd., is a work-class ROV that can be used in emergency rescue, marine salvage, and undersea engineering projects.

Weighing five tonnes and equipped with a 250 horsepower engine, the ROV can dive to a depth of 3,000 meters and lift up to four tonnes.

It can further enhance China's capabilities of carrying out deep sea operations including marine salvage and seabed construction.
