FacebookTwitterEmailLinkedin

China’s  project of “deep-sea key technology and equipment” has made new breakthroughs, as the “ship-borne unmanned submersible retractable system” developed by the country has  passed the standardized sea test acceptance.

The sea test aims to evaluate the effects and functional indicators of the unmanned submersible retractable system and its supporting retractable docking device.

During the sea test, the testers used a gantry-type lifting device equipped with a powered underwater active retractable cage, grab-type retractable cage and other retractable and docking devices, which were used for unmanned submersibles in complex sea conditions.

Commenting on the development, Jiang Yuliang, general manager of China State Shipbuilding Corporation Nanjing CSSC Oasis Zhenjiang Auxiliary Machinery, explained that this technology could effectively reduce the impact of waves and ship swaying on the deployment and recovery process of unmanned submersibles under complex sea conditions, and greatly improve unmanned submersibles.

In the future, with the development of the marine economy to the deep sea, there will be more scientific research activities such as the exploration of deep sea mineral resources and marine biological investigation.

The success of the sea test of this project also marks the further improvement of China’s application capabilities in the field of shipborne unmanned submersible retractable systems.
