Sealien Robotics

The company's product line includes remotely operated vehicles (ROVs), trenchers, and ploughs designed for deep-sea operations such as cable and pipeline burying. Their systems are engineered for functions at depths up to 3,000 meters, with some ROVs capable of reaching 10,000 meters. A notable product is the 'Taurus' robot, which is entirely developed and produced domestically in China. In early 2025, Sealien announced it had secured a contract with a major Chinese power engineering group for a high-end subsea cable burial plough system capable of trenching up to 6 meters deep at depths of 650 meters and laying two cables simultaneously. The firm also made a sale of a deep-sea surveillance system to an undisclosed buyer in the Middle East, a key market for subsea surveillance due to extensive offshore energy facilities.

Sealien's business model encompasses manufacturing and sales, as well as a suite of services including leasing, maintenance, technical support, and component supply. The company aims to provide a full-cycle service system, from research and development to delivery and after-sales support, to clients in the offshore energy and marine engineering sectors. The company has received funding from investors including Xingzhi Capital.
