The New Year’s bell has just sounded, and the scientific research report of the Tianjin Port Facilities Center has been frequently reported. “Study on the new technology of the Tianjin Port 250,000-ton waterway slope and the 300,000-ton berth water depth maintenance†and “Tianjin Port Sedimentation and Environmental Assessment†The project passed the appraisal of water operation industry experts organized by Tianjin Science and Technology Evaluation Center, and the two scientific research achievements have reached the international advanced level.
It is understood that the first project is aimed at the status of sedimentation and siltation of the 250,000-ton waterway. The measurement cycle of the sea-funded water depth map is encrypted once a month to twice a month. The corresponding muddy weight of the floating depth is 1.25 tons per The cubic is increased to 1.28 tons per cubic meter, which not only ensures the safety of navigation, but also increases the navigation depth of about 0.4m, which is the first in China. The “Deep Water Channel Deepener†with independent intellectual property rights is flexible and has a large working water depth. It can increase the seaworthiness of water depth by about 0.6m every time it is implemented. It is one of the effective means of Tianjin Port deep water channel emergency support. The water depth proposed by the project maintains the principle of “shallow water level segment†and adopts the maintenance of new technologies and new processes. Compared with the traditional process, the effect of reducing siltation is obvious, and it has great promotion value in the water depth maintenance market of muddy ports.
As a sub-project of the above two projects, “300,000-ton port berths, suitable for air-deepening and deep water depth maintenance new technology†passed the expert appraisal in January last year, and the achievement level reached the international advanced level. At present, the result has been transformed into productivity. Last year, the 300,000-ton full-load tanker was safely berthed 10 times, and the annual maintenance cost was about 20 million yuan.
