8A4 class ROUV is a remotely operated underwater vehicle (ROUV)
various underwater tasks, ranging from oil platform service to salvage and rescue missions
Team members included the 702nd Research Institute of the China Shipbuilding Industry Corporation (CSIC), the Shipbuilding Engineering Institute of Harbin Engineering University (HEU), and the Institute of Underwater Engineering of Shanghai Jiao Tong University (SHJTU)
Xu Huangnan (徐芑南), a professor of SHJTU, was named as the general designer of the 8A4 ROUV
two manipulators that could operate around half a dozen tools
Tether Management System (TMS)
first 8A4 ROUV completed sea trials in 1993, operating at a depth of up to 600 meters
with a cruising radius of up to 150 meters
Except for the first unit, all the remaining 8A4 ROUVs have had their TMS removed due to the budget cuts, resulting in a significant reduction in performance, such as reducing the maximum operational depth by more than half
The Chinese 8A4 class ROUV is a remotely operated underwater vehicle (ROUV) used to perform various underwater tasks, ranging from oil platform service to salvage and rescue missions. The 8A4 is a member of a series of related ROUVs developed by the Shenyang Institute of Automation (SIA) in the People's Republic of China (PRC). The predecessor to the 8A4 was the RECON-IV, an improved version of the American RECON-III. The 8A4 itself is an upgraded version of the American AMETEK 2006, and the 7B8 is an improved version of the 8A4.
