CCCC had completed the technical research underpinning its planned 10,000-tonne-class deep-sea engineering survey ship by October 12, 2026. The first-stage results of a BeiDou-based survey-system project passed expert review after two years of work. That was a design and research milestone—not delivery of a working vessel: construction had not begun. 6

What the expert review covered
CCCC Highway Consultants led the Phase II project, “Research, Development and Application of a BeiDou-Based Intelligent Comprehensive Deep and Far-Sea Survey System.” Reports describe a team bringing together academicians, master experts and professional researchers from inside and outside CCCC. They do not name individual team members or the review-panel experts. 6
8
The reviewed work brought together proposed ship design and survey equipment for drilling, seabed measurement, geotechnical testing, geophysical exploration, and hydrological and meteorological investigation. 6

Proposed drilling and seabed-testing systems
The planned drilling package combines a large-bore top drive designed for multiple coring methods, automated deck operations, and a traveling-block system with active–passive heave compensation. The reported design rating is a compensation stroke of ±3 meters and a load of 150 tonnes, as part of a 5,000-meter-class deepwater drilling-equipment proposal. 6
7
Heave compensation is intended to limit the effect of a vessel’s wave-driven vertical motion on suspended drilling equipment. In an active–passive system, those approaches work together to counter movement. The available reporting gives the proposed stroke and load ratings, but not enough detail to establish the system’s exact mechanics or how it performs at sea. 6
7
For in-situ ground testing, the team developed an integrated downhole static cone-penetration and bottom-hole static-pressure sampling proposal. Its reported design parameters are water depths up to 1,500 meters and a penetration force of 100 kilonewtons. 6
7
BeiDou positioning and coordinated surveys
The research established a high-precision BeiDou time–space reference and a related measurement, control and mapping system for deep- and far-sea engineering surveys. It also set out geophysical survey methods and equipment arrangements combining the main vessel with crewed and uncrewed boats. 6
7
For environmental observations, the plan specified equipment selection and integration for hydrological and meteorological surveys, alongside a data-fusion and tiered-warning management platform. These are reported design and research outputs; they should not be confused with proven capabilities of an operating ship. 6
7
The proposed vessel, named “Zhong Jiao Long” in reports, was developed around the design principles of function, aesthetics and human factors. 6
7
Reported results—and the limits of the claims
Project reporting lists two hardware-equipment items, 31 technical proposals, 14 software copyrights, 22 high-quality papers and 39 invention-patent applications. The patent total refers to applications, not confirmed grants. 10
A contemporary industry report characterized the technology as internationally advanced overall, with some elements internationally leading. That is a reported assessment, not evidence that the complete vessel or all of its systems had been independently tested in full-scale sea operations. 10
What remained ahead
The milestone was completion of technical research and the passage of the project’s first-stage results through expert review. The reports describe a proposed, integrated survey ship, but confirm that construction had not yet begun. Its design ratings are therefore plans, not demonstrated operational results. 6
