Nanjing four-color warning for inland navigation

The inland waterway of Nanjing has the warning of “red, orange, yellow and blue”. It is learned from the Nanjing Local Maritime Safety Administration that the “four-level color warning” system is a summary of the characteristics of the Nanjing river water traffic accident in the past 20 years, according to the inland river hydrology changes. The weather situation analysis, for the inland river water level, flood peaks, wind power, visibility, etc., which may cause water emergencies, the blue level is the level IV representative hazard, the yellow level is large (level III), and the major is orange. (Level II), especially significant red (Class I).

Recently, the Nanjing River Water Search and Rescue Center found in the monitoring room that the “Jiangsu Drag 1696” was launched when the Qinhuai Xinhe Hongmiao Bridge section was suddenly rolled, and the six vessels loaded with coal were overturned at any time.

The water level in the lower reaches of the Yangtze River has hit a new high and the water level in the river has also risen. According to the water level situation, Nanjing Inland Water Search and Rescue Center issued orange (significant, grade II) warning information to all relevant units, navigation vessels and maritime administrative agencies within the system in time, and all units are in a state of war, so that they can A quick response like this emergency. In order to earnestly fulfill the solemn promise of “one hour after maritime police reception and 95% success rate of water search and rescue”, Nanjing Local Maritime Safety Administration has established a long-term management mechanism for “four-level early warning and unified release” of water safety to divide early warning information. It is a general (blue, grade IV), large (yellow, grade III), major (orange, grade II), special (red, grade I) four-level warning hazard information, the purpose of which is to improve the safety of inland water traffic. Prevent emergency response and handling capabilities for pre-control and emergency events.

And search and rescue capabilities have been tested in actual combat.

Zheng Chunfa, director of the Office of the Inland River Water Search and Rescue Center of Nanjing, and the director of the Municipal Local Maritime Safety Administration, said: "The establishment of the 'four-level color warning' mechanism is based on the inland river hydrology changes and weather conditions, and the inland water level and flood peaks that may cause water emergencies. Early warning information such as wind, visibility, etc., according to the urgency, hazard degree and scope of impact that may cause water danger or accident, the warning information is divided into four levels of warning information: blue, yellow, orange and red, and passed '96196 'Transportation service hotline SMS group, TV monitoring system, GPS system, fax and other effective means, the Nanjing River Water Search and Rescue Center to the navigation, berthing, operation of ships, ferries, shipping companies, etc. to release a long-term management mechanism. The aim is to improve the emergency response and disposal capacity of sudden waterborne traffic incidents."
