The Ministry of Transport released data, Last year, more than 90 deep-water channels of 100,000 tons or above were built in coastal ports across the country, and the overall scale of my country's deep-water channels has ranked first in the world.
data shows that as of the end of 2021, more than 90 deep-water channels of 10,000 ton and above have been built in coastal ports across the country, and all 10 international hub ports have deep-water channels for container ships that are navigable for 150,000-200,000 tons; ports such as Dalian, Tangshan , Qingdao , Ningbo Zhoushan, Zhanjiang , Meizhou Bay and other ports have deep-water channels for navigable for 400,000 tons of bulk cargo ships.
After years of construction, my country's overall scale of deep-water waterways has ranked first in the world, and the smart green level of waterway construction has been continuously improved.
Deputy Director of the Water Transport Bureau of the Ministry of Transport Zheng Qingxiu said that the rapid development of deep-water waterways has further improved the security and resilience of coastal transportation channels and port hub nodes, effectively guaranteed the stability of my country's logistics supply chain, smooth domestic and international dual circulation, and higher-level opening up, and strongly supported my country to become the world's largest country in goods trade and economic and social development. What is the difference between a route and a waterway?
In addition to deep waterways, the construction of deep waterways is also accelerating. So, what is the difference between a route and a waterway?
Simply put, the waterway refers to the channel that can be used for navigation in inland waters such as inland waters, lakes, and the channel that can be used for navigation in inland seas and territorial seas through construction and maintenance. The route mainly uses existing water resources, and then provides the passage for ships to communicate through maritime and other departments.
3 opens Bohai .4 million tons deep water new shipping route
In the past decade, the construction speed and scale of Bohai Bay ports have increased rapidly. Expanding the berthing terminal of super-large ships of 300,000 tons or above, improving the tonnage level of berthing ships, and reducing transportation costs are the priority choices for each port. Exploring the opening of deep-water routes for super-large ships in the Bohai Sea has become an urgent task.
Recently, the "Yuanjinhai" ship carrying 390,200 tons of ore sand was carried by the new route in the central Bohai Sea and safely berthed at the Caofeidian Port Ore Wharf, Hebei Province, which marked the successful opening of the "new channel" of the deep-water route of the 400,000-ton giant ship entering and leaving the Bohai Sea.
"will further release the potential of our deep-water port, while ensuring the security of the national iron ore industry chain and supply chain, and promoting the high-quality development of the hinterland steel metallurgy industry ." said Wang Kesheng, chairman of Caofeidian Port Group Co., Ltd.
It is understood that the 400,000-ton ore sand ship is called the "big master" at sea. It has the only 400,000-ton ore terminal in the Bohai Bay. Due to the lack of accurate water depth data on other routes, the 400,000-ton ore sand ship has been loaded and berthed, and the port berthing capacity is difficult to fully and effectively exert. Dong Jiang, director of Tianjin Maritime Surveying and Mapping Center of the North Sea Maritime Supply Center, introduced: "We use multiple beam depth sounding systems, magnetometer detection systems and other sea sweeping measurement methods to accurately measure the water depth of the routes entering and leaving the Bohai Sea, explore the distribution of obstacles along the route, and master important data to meet the navigation depth of super-large ships." Li Baodong, director of the Caofeidian Maritime Bureau, said: "We follow the measures of measuring the depth of water and precise tides, and take the routes in the central Bohai Sea to take the routes in the Bohai Sea. South, we found three key deep-water sections, further grasped the water depth characteristics and tidal laws of the new route of 400,000-ton super-large ships from the old Tieshan Riverway to Caofeidian, and opened up this new deep-water route. "
digital intelligent platform ensures the safe navigation of super-large ships
In order to ensure the safe entry and exit of super-large ships with full load, the maritime department has also developed the "Super-large ship safety navigation intelligent control platform", implementing full-process tracking and monitoring of ships entering deep-water routes to ensure the safety of ships.
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 recognition area, the ship's location, speed, node time, and pre-appointed time will form an instant message, which will be pushed to the intelligent control platform in real time, and dynamic tracking will be implemented throughout the process to grasp the ship's passing through deep water routes in real time.
At the same time, the platform uses the tide model of the ship's intelligent tide ride module to calculate tide information in real time, and designs an accurate tide ride model for the shallowest waters of the deep-water routes to safely pass through the ship. During the entry of the Bohai Bay, a safe speed is set to ensure the safe passage of the ship using the tide. At the same time, a long-distance transportation organization is carried out. Other ships are asked to avoid in advance to ensure the smooth flow of deep-water routes.
Deputy Director of Caofeidian Maritime Bureau Zhang Yiqing introduced: "We accurately predict the arrival time of the ship based on the stored historical data and combined with the real-time dynamics of the ship. We also rely on the ship transportation service system and the automatic ship identification system for monitoring, and use drone air cruise, maritime patrol boat pilot escort, monitoring and other means to ensure the navigation safety of super-large ships entering and leaving the Bohai Sea deep-water route."
