Hailong 2

"Hailong II" [Sea Dragon] has a maximum working depth of 3,500 meters, a length of 3.17 meters, a width of 1.81 meters, a height of 2.24 meters, and a weight of 3.45 tons. It is connected to the mother ship through a cable, and the remote control is supported by the operator. The submarine image from the cable remotely controls the submersible movement and manipulator operation. Its outstanding advantage is that it has long working time in the underwater, and is mainly used for deep sea exploration and scientific investigations such as deep sea hydrothermal sulfide, biology and environment.

A specialist Chinese vessel carrying unmanned submersibles Qianlong No. 1 and No. 2 set off on a 170-day scientific expedition in the southwest Indian Ocean on Wednesday. Xiangyanghong 10, on its maiden voyage on deep-sea areas, set sail on Wednesday from the port city of Sanya in south China's Hainan Province with an expedition team of 232 members. During the voyage of more than 24,000 km, the submersibles will explore metal sulfides and conduct environmental and biodiversity surveys in the Indian Ocean in accordance with a contract signed by China and the International Seabed Authority. China is being more efficient and saving resources through this new approach of carrying the two submersibles on one ship, said Li Jiabiao, a research fellow with the State Oceanic Administration.
