Discovery (Fa-xian, 发现 in Chinese) remotely operated underwater vehicle (ROUV) is a type of very little known unmanned underwater vehicle (UUV) originally built in Great Britain by British firm Specialist Machine Development (SMD) Limited for the People's Republic of China (PRC).[1][2][3][4][5][6][7][8] and the British firm was later purchased by CSR Corporation Limited in April 2015.[9]

Equipment

In order to complete its assigned missions, Discovery ROUV is equipped with seven underwater cameras, two high definition cameras, underwater positioning system, one Titan 4 and one Atlas manipulators,[2][6] each is capable of handling objects weighing up to 120 kg,[2] and when used together, objects weighing up to 300 kg can be handled.[6] In addition, there are more than thirty different kinds of scientific instruments and equipment indigenously developed in China for the ROUV after it entered service.[7]

Specification

  • Length: 3 meter
  • Width: 1.7 meter
  • Height: 2 meter
  • Payload: 300 kg[2]
  • Maximum operating depth: 6000 meter

Upgrade

Merely less than half a decade after entering service, Discovery ROV went through an upgrade that lasted more than half a year in China, from end of October 2018 thru April 2019.[7] It's reported that during this maintenance/upgrade, by incorporating more advanced technologies, the maximum operating depth is increased by a third, to the original 4,500 meters to 6,000 meter after Discovery ROV returned to service.[3][4] The mothership of Discovery ROUV has been Chinese research ship Science (Ke-Xue, 科学)[1][2][3][5][6][7][8] since the ROUV first entered service in 2014.[1][2][3][5]
