  • Machining Center

Equipped with advanced five-axis CNC machining centers, turning-milling composite centers, lathes, boring and grinding machines, wire cutting, EDM, and welding facilities. The center provides high-precision machining and maintenance for complex components, enabling self-developed production of specialized instruments and non-standard parts.

  • Comprehensive Test Pool

Dimensions: 22 m (L) × 10 m (W) × 20 m (D) .

Main applications include:

• Underwater commissioning and demonstrations for HOVS, ROVs, AUVs, gliders, and landers

• Material corrosion resistance and sealing tests

• Mooring system, docking, and communication experiments

• ROV/HOV driver training and operational procedure testing

  • Marine Equipment Integration and Commissioning Center

Responsible for the assembly, calibration, testing, and maintenance of large-scale equipment such as unmanned and manned submersibles, providing technical and spatial support for the Research and Development of marine scientific instruments.

  • Yazhou Bay HOV Engineering Laboratory

The laboratory is located at the Nanshan Port site with a total area of approximately 880 m². It was officially inaugurated in June 2023, and currently, human-occupied vehicle (HOV)  has been officially stationed there. The facility houses the world’s first 200 MPa large-volume Deep-Sea Low-Temperature Hydrostatic Test System (Model 20/10) and is open to the public for shared use, supporting the operation, maintenance, and shore-based testing of manned/unmanned submersibles and other deep-sea scientific equipment.
