Dynamics of various places 丨 Shanghai Maritime Surveying and Major Center for 10 years to help Lianyungang Port 300,000 -ton channels for comprehensive completion

Recently, the second phase of the 300,000 -ton channel of Lianyungang Port, the second phase of the Xuyu Channel of the Xuwei Channel passed the work acceptance, which marked the comprehensive completion of the 300,000 -ton channel of Lianyungang Port, and also served the 300,000 -ton level of Lianyungang Port and Hong Kong and Hong Kong, Shanghai Maritime Surveying and Mapping Center, the East China Sea Lama Conservation Center. The staged construction of the channel is a complete end.

In 2009, the National Development and Reform Commission approved the construction of a 300,000 -ton channel of Lianyungang Port. This is one of the largest coastal channel projects with the largest investment in my country. Overlooking from the air, a "human" font channel connects the main port area and the Xuyu port area.

In accordance with the principle of "one -time projects and installment implementation", Lianyungang Port was completed in 2016 and 2020, respectively, and the first phase of the project and the second phase of the project main port area. To start the work and acceptance, it is marked that the entire project is fully completed.

Entrusted by the 300,000 -ton channel construction headquarters of Lianyungang Port, as one of the channel participating units, the Shanghai Maritime Surveying and Majesty Center has continued to provide sailing services such as scan testing and positioning for the construction of 300,000 tons of channels in Lianyungang Port.

The first phase of the channel project, 250,000 tons of channels, recommended routes and anchors were officially opened in 2016.

The construction of the second phase of the channel started in September 2017. The Shanghai Maritime Surveying and Majesty Center completed the sixth anchor and connecting waters, the seventh anchor, and the eighth anchor in 2019. The route sweeping and testing was completed in 2022 to complete the channel sweeping test of the Xuwei Port District, providing a timely and efficient navigation guarantee service for the successful construction of the 300,000 -ton channel of Lianyungang Port.

In the process of serving the 300,000 -ton channel of Lianyungang and Hong Kong, the Shanghai Maritime Surveying and Maeration Center continued to promote the cultivation of the "one specialized" maritime test talent team and the development of science and technology relying on major national projects. Relying on the high -precision Beidou CORS positioning system built independently, combined with the Land and Sea vertical benchmark conversion and unified science and technology projects carried out by the East China Sea District, the high -precision surface model of the East China Sea District is used to support the new sea platform tide for 300,000 tons of channels. The station sets the control point and establishes a high -prime benchmark. Based on the self -developed East China Sea Tide Model, the high -resolution tidal mathematical model of the coastal area of ​​the northern Jiangsu area is established. While using the tide data of the tide of the tide test instrument, the method of reorganization of the remaining water level is improved. The remaining water level is to order the model forecasting position of the neighboring sea area, and it changes the traditional operating mode of the tide position to obtain the tide position at the sea. At the same time, based on the enhancement system of Beidou CORS foundation in the East China Sea, the application of offshore long -distance and high -precision differential positioning is achieved, and the RTK/PPK unparalleled moisture testing mode of the Lianyungang waters has been successfully carried out, which greatly improves the measurement efficiency of the navigation scale.

With the completion of the 300,000 -ton channel of Lianyungang and Hong Kong, Lianyungang has therefore become the only one with 300,000 -ton channel deep -water port, national railway hub and highway network, 4D airport, covered with Su Lu, Henan and Anhui inland network, etc. National comprehensive transportation hub.
