SJT-class ROUVs are a series of Chinese remotely operated underwater vehicles (ROUVs) jointly developed by the Shenyang Institute of Automation of the Chinese Academy of Science and the Institute of Underwater Engineering of Shanghai Jiao Tong University (SHJTU).
The origin of SJT-class ROUV begins with HR-01 (Chinese: 海人一号; pinyin: Hai-Ren Yi-Hao; lit.
[3] Based on experience gained from HR-01, the three subsequent SJT-class ROUVs were jointly developed with a Canadian company[which?]
The aluminum-framed SJT-10 is equipped with a digitized depth gauge, compass, sonar, lowlight TV camera, and an onboard computer.
Like other SJT-class ROUVs, it is in service with both civilian and military operators, mainly in underwater maintenance work of oil platforms and other structures.
Similar to its predecessor, HR-03 is also a small ROUV[5] capable of performing additional tasks besides observation, such as sample collection and underwater construction.
[8] Specifications:[8] ST-6000 is an ROUV designed for deep-sea observation missions; it was completed in June 1995.
In addition to a drastic reduction of size and weight, it does not have a manipulator, and the maximum operational depth is reduced by half, to 100 meters.
The first customer of the JH-01 was Hai He Hydraulic Works Committee,[1][2] and its satisfactory performance led to more orders from different customers, including the People's Liberation Army Navy (PLAN), which deployed JH-01 for breakwater inspection and maintenance.
