The Yangtze River estuary, the ship has a chapter to follow
The Shanghai section of the Yangtze River is connected to the Jiangsu section of the Yangtze River and the Yangtze River estuary, including the Yangtze Estuary Deepwater Channel, Nangang Channel, South Branch Channel, Baoshan Channel, etc. It is 65 nautical miles long and is the main passage for ships to enter and exit Shanghai Port and the Yangtze River. It is one of the world's most famous navigable areas. It is the only water transport channel for ships to enter and exit the Shanghai Port and the Yangtze River Basin. In recent years, with the rapid development of Shanghai's shipping economy, the number of ships sailing in the Shanghai section of the Yangtze River has increased, showing a trend of large-scale, specialized, high-speed and diversified. According to incomplete statistics, the current flow of ships in the navigational waters of the Shanghai section of the Yangtze River is increasing at a rate of about 15% per year, of which large ships account for 60%. Due to the limited navigation resources, large and small ships can usually only mix and match formations. Large ships often waste a lot of valuable time to avoid small ships that take the tide. This kind of situation can not meet the development requirements of the modern logistics industry for fast-forward and fast-moving shipping, and it is even unable to meet the people's requirements for navigation safety. On the other hand, some ships are unfamiliar with the route and disorderly navigation, which makes this water area a frequent occurrence of water traffic accidents. How to safely and quickly sail a ship is a focus of research and concern in the shipping industry.
Since 2004, the Shanghai Maritime Commission Jiang Shanghai section of the ship alignment system has carried out five sections including Liuhekou Port Line, Baosteel Luojing Wharf, Wusongkou, Yuanshasha Light Ship and Jiuduan Lightship in different tide periods. The 24-hour uninterrupted navigation flow observation and the comparison and analysis of the navigation flow photos of the two-week aerial inspection showed that the route set by the ship alignment system of the Shanghai section of the Yangtze River not only meets the water depth requirements, but also meets the water flow conditions and is also in line with the crew's habits. It is in line with the actual situation of navigation. In addition, the maritime supervision methods and capabilities have been fully demonstrated. Five maritime offices, including Wusong, Waigaoqiao, Baoshan, Chongming and Yangshan Port, have been set up in the waters of the Shanghai section of the Yangtze River to build a water system that covers the entire ship's alignment system. VTS system, CCTV monitoring system, AIS base station was set up along the coast, and a maritime GIS integrated management system based on information resources integrating AIS, VTS, CCTV and CHISREP was constructed. More than 30 law enforcement boats were established, and integrated navigation management was established. A long-term management mechanism for shipwreck search and rescue, ship supervision, and pollution prevention, and equipped with maritime management personnel with excellent business and strong capabilities, and has strong supervision and management capabilities in respect of the alignment system.
Facts have proved that the implementation of the regulations over the years, according to the Shanghai Maritime Safety Administration VTS key ship monitoring statistics, from April 2003 to December 2006, the flow of ships entering and leaving the South Trough was basically stable and gradually increased. Before the implementation of the Regulations, the average monthly rate was 2,998. After the implementation of the Regulations, the average monthly rate reached 4,570 ships, with a monthly growth rate of 1,572 ships. The average annual growth rate of ship traffic flow into and out of the North Channel Channel and the South Channel Channel of the Shanghai section of the Yangtze River was 7.38% and 38.67%, respectively. The deadweight of ships entering and leaving the north section of the Yangtze River in Shanghai is 4,1181.8 tons.
The average deadweight of ships entering and leaving the southern section of the Yangtze River Shanghai section is 2,000 tons. The implementation of the ship alignment system in the Shanghai section of the Yangtze River has better adapted to the development trend of large-scale ships. The number of ships with a draught of more than 10 meters in the Shanghai section of the Yangtze River increased slowly before 2003. However, with the dredging and digging of the Yangtze River channel and the implementation of the ship alignment system in the Shanghai section of the Yangtze River, the navigation environment of the Yangtze River was improved. The increase is obvious. Compared with the same period of the year before and after the implementation of the "Regulations", the large draft vessels that entered and exited were 1.26 times before the implementation of the "Regulations", and the Regulations increased by 2,153 ships per year after the implementation.
The implementation of the Regulations has brought significant social and economic benefits. The improvement of the security situation has reduced the loss of people's lives and property, and protected the fundamental interests of the broad masses of the people; the improvement of the navigation environment has improved the speed of navigation of ships, and has also avoided the occurrence of major accidents, speeding up the circulation of goods at various ports and promoting The increase in cargo throughput has contributed to the rapid development of Shanghai's economy; the improvement of the navigational order and the improvement of the navigation environment have also changed the investment environment of Shanghai, making Shanghai's advantages more obvious and the port's competitiveness to be significantly improved.
Huangpu River navigation safety management regulations show social and economic benefits
After entering the 21st century, the function of Huangpu River will be adjusted according to Shanghai's overall plan and the 2010 Shanghai World Expo plan. In the future, the large ships of the Huangpu River Shuiyu will be less and less, while small ships, yachts and tourist ships will come back. The more the adjusted Huangpu River will be built into a commercial, tourism and green sightseeing area to achieve the transformation to the tertiary industry and service functions. In April 2006, the “Huangpu River Navigation Safety Management Regulations†was officially implemented. In the past year, the reform of the Huangpu River route has achieved remarkable results, the security situation has improved significantly, the ship operation efficiency has been significantly improved, the port competitiveness has been significantly enhanced, and the advantages of Shanghai Port have become more prominent. Promote the growth of economic benefits. According to statistics, before the implementation of the regulations, the average number of accidents per month was 6.63. After implementation, the average number of accidents per month was 4.08, the rate of accident reduction was 38.40%, and the number of accidents reduced by 30.56 in 12 months, reducing the actual safety after direct economic losses. The economic benefit is 2,873,600 yuan.
The implementation of the "Provisions" promoted the development of the tanker economy in Shanghai Port. The formulation and implementation of the "Huangpu River Navigation Safety Management Regulations" made the existing distribution of navigation resources more reasonable, and the landscape advantages along the Huangpu River were effectively utilized. Huangpu River The changes in the navigation environment of the ship, the improvement of navigation safety and the improvement of navigation efficiency have met the requirements of international tourism for navigation safety, which has attracted international cruise ships. More and more large luxury cruise ships are coming to Shanghai to stop. The Huangpu River shoreline function The change brought an opportunity to the Shanghai cruise economy. According to statistics, in 2005, Shanghai Port received 77,000 passengers, and the economic benefits of cruises reached US$103 million. According to the news from the border inspection department, there were 32 international luxury cruise ships berthed in 2006. Shanghai Port has a total of 114 voyages of cruise ships in and out of Shanghai Port, bringing 62,500 foreigners and employees to Shanghai. The corresponding economic benefits can reach US$124 million, an increase of US$21 million in 2005 compared with the pre-implementation. Experts predict that during the Shanghai World Expo, it is estimated that there will be 2 million Chinese and foreign guests arriving in Shanghai through the waterway, and at least four luxury cruise ships will enter and leave Shanghai at home every day. Since 2007, there have been more than 30 large-scale luxury cruise ships around the world with a schedule of coming to Shanghai during the year. A total of more than 110 flights have been made in Shanghai Port, and the number of passengers carrying passengers will exceed 100,000. It is reported that the 1,000-person "Aregra" luxury cruise ship will be the first to use Shanghai as the home port to open a cruise line flight from Shanghai - Japan Nagasaki - South Korea's Jeju Island, scheduled to be hosted on the route every year. 55,000 visitors.
Relevant experts said that the promulgation of the two "Regulations" in Shanghai will minimize the cross-over of the route and the phenomenon that the big ships and small boats will fight together and influence each other, so that the ship can be navigated; the ship alignment with the Yangtze River Jiangsu section is realized. The effective connection between the system and the Yangtze River estuary line system has opened up the “high-speed waterway†of the Yangtze River Shipping. The implementation of the "Regulations" also laid a solid foundation for the functional change and route reform of the Huangpu River in Shanghai, and provided a guarantee for the implementation of ship separation. At the same time, it will also bring significant social and economic benefits to Shanghai and the Yangtze River Delta, making Shanghai's image more prominent and the port's competitiveness more obvious, making Shanghai's mother play an increasingly important role.
