The overall scale of my country's deep water channels ranks first in the world
According to data released by the Ministry of Transport, more than 90 deep-water channels of 100,000 tons and above have been built in coastal ports across the country last year, and the overall scale of my country's deep-water channels ranks first in the world.
Data shows that by the end of 2021, more than 90 deep-water channels of 100,000-ton and above have been built in coastal ports across the country, and all 10 international hub seaports have deep-water channels for 150,000-200,000-ton container ships; Dalian, Tangshan, Qingdao, Ningbo Zhoushan, Zhanjiang, Meizhou Bay and other ports already have deep water channels for navigating 400,000-ton bulk cargo ships.
After years of construction, the overall scale of my country's deep-water channels has ranked first in the world, and the smart and green level of channel construction has been continuously improved.
Zheng Qingxiu, Deputy Director of the Water Transport Bureau of the Ministry of Transport: The rapid development of deep water channels has further improved the safety and resilience of major coastal transportation channels and port hub nodes, and effectively guaranteed the stability of my country's logistics supply chain, smooth domestic and international circulation, and higher levels of transportation. Opening to the outside world has strongly supported my country's development as the world's largest trader in goods and its economic and social development.
What is the difference between airway and fairway?
In addition to the deep water channel, the construction of the deep water channel is also accelerating.
So, what's the difference between an airway and a fairway?
In simple terms, waterways refer to passages in inland waters such as inland rivers and lakes that can be used for navigation by ships, as well as passages in inland seas and territorial seas that can be constructed and maintained for navigation by ships.
The shipping route is mainly a channel for ships to travel after professional detection of water depth and analysis of navigation conditions by the maritime department and other departments by using the existing water resources.
Open up a new deep-water route for 400,000-ton ships in the Bohai Sea
In the past ten years, the construction speed and scale of Bohai Bay ports have increased rapidly. The expansion of the berthing terminals for super-large ships of 300,000 tons and above, the improvement of the tonnage level of berthing ships, and the reduction of transportation costs are the preferred choices of ports.
It is a top priority to explore the deep water route of super-large ships in the Bohai Sea.
Recently, the "Yuanjinhai" vessel carrying 390,200 tons of ore sand passed through the new shipping route in the middle of the Bohai Sea, and safely berthed at the ore terminal of Caofeidian Port in Hebei Province, marking the successful opening of the "new channel" for the 400,000-ton-class deep-water shipping route into and out of the Bohai Sea.
Wang Kesheng, Chairman of Caofeidian Port Group Co., Ltd.: It will further unleash the potential of our deep-water port, at the same time ensure the safety of the national iron ore industry chain and supply chain, and promote the high-quality development of the steel and metallurgy industry in the hinterland.
It is understood that the 400,000-ton ore carrier is known as the "big mac" at sea. Caofeidian Port, which has the only 400,000-ton ore terminal in the Bohai Bay, has no accurate water depth data for other routes, so the 400,000-ton ore carrier has been The berthing capacity of the port cannot be fully and effectively exerted due to load reduction and berthing.
Dong Jiang, Director of Tianjin Maritime Surveying and Mapping Center, Beihai Navigation Support Center: We have used a variety of sea sweeping measurement methods such as multi-beam bathymetry system, magnetometer detection system, etc., to accurately measure the water depth of the routes entering and leaving the Bohai Sea, and identify obstacles along the route. distribution, and mastered important data to meet the navigation depth of super-large ships.
Li Baodong, Director of the Caofeidian Maritime Safety Administration: According to the measures of measuring the water depth and adding precise tides, we found three key deep-water voyages in the south of the central Bohai Sea route, and further mastered the 400,000-ton super-large ships from Laotieshan Waterway to Caofeidian New The water depth characteristics and tidal rules of the route have opened up this new deep-water route.
Digital intelligent platform ensures safe navigation of super-large ships
In order to ensure the safe entry and exit of super-large ships with full loads, the maritime department has also developed an "intelligent control platform for safe navigation of super-large ships", which implements the whole process of tracking and monitoring of ships entering deep water routes to ensure the safety of ships' navigation.
The reporter saw that once a ship wants to enter the port, the platform can set the ship parameters in advance, and set the key monitoring area for the ship in the intelligent perception module. When the ship sails into the identification area, the ship's position, speed, node time, pre-arrival The time will form an instant message, which will be pushed to the intelligent control platform in real time, and it will be dynamically tracked throughout the whole process, and the situation of the ship passing through the deep water route will be grasped in real time.
At the same time, the platform uses the tide model of the ship's intelligent tide riding module to calculate the tide information in real time, and design an accurate tide riding model for the ship to safely pass through the shallowest waters of the deep water route. , and carry out long-distance transportation organization at the same time, and ask other ships to avoid in advance to ensure the smooth flow of deep water routes.
Zhang Yiqing, Deputy Director of Caofeidian Maritime Safety Administration: We accurately predict the arrival time of ships based on the stored historical data and the real-time dynamics of ships.
Relying on the ship traffic service system and the ship automatic identification system for monitoring, and using unmanned aerial vehicle cruise, sea cruise ship pilot escort, monitoring and other means, the navigation safety of super-large ships entering and leaving the Bohai deep water route is fully guaranteed.
