SBSS UUV
SBSS unmanned underwater vehicles (UUV)s are remotely operated vehicles (ROV)s developed in the People's Republic of China (PRC) by S.B. Submarine Systems (SBSS, 中英海底系统有限公司), a joint venture between Global Marine Group (GMG) and the China Communications Services,[1]and they are mainly used for under underwater cable laying and maintenance.[2]

- Cable burial depth: 3 meter
ST200 Sea Lion I[edit]
ST200 Sea Lion (Hai-Shi, 海狮 Chinese) I ROUV is designed to dig trenches for laying underwater cables.[6]Unlike other SBSS UUVs, ST200 Sea Lion I did not enter service for underwater cable laying, neither did it enter service for oil exploration, but instead, it entered service in 2009 as a scientific research tool onboard Chinese research ship Ocean 6 (Hai-Yang 6-Hao, 海洋六号) for geological researches.[7][8] Specification: [6]
- Maximum depth of operation: 2500 meter
- Propulsion: six 12” horizontal & four 12” vertical thrusters
