The new generation of universal maritime data model S-100 real ship sea trials were carried out in the Pearl River Estuary

China News Service, Guangzhou, October 17 (Guo Jun Gui Zilin) ​​The South China Sea Navigation Support Center of the Ministry of Transport of China organized a real-ship sea trial of the new generation general maritime data model (S-100) in the Tonggu Channel of the Pearl River Estuary on the 16th. Shenzhen Maritime Safety Administration, Hong Kong Marine Department and other units participated to jointly promote the implementation of the S-100 standard in the Guangdong-Hong Kong-Macao Greater Bay Area.

S-100 is a new generation of universal marine data model standard proposed by the International Hydrographic Organization (IHO). It is the basis for realizing intelligent navigation at sea. Compared with the S-57 standard, which only supports static electronic charts, S-100 can superimpose information layers related to maritime navigation safety such as water level, water depth, navigation rules, etc. on the standard electronic chart as needed to realize linked calculations and automatic push of navigation aid information. Just like using land navigation, the crew can grasp the navigation environment and navigation aid information on one screen.

According to the schedule of the International Maritime Organization (IMO), newly installed electronic chart display and information systems (ECDIS) must meet the S-100 standard from January 1, 2029. This standard switch will bring major changes to the shipping industry. S-100 can improve navigation safety, improve navigation efficiency, optimize ship cargo capacity, and provide support for intelligent shipping and autonomous navigation. At the same time, with the help of real-time hydrological information, it can reduce fuel consumption and carbon emissions, and promote shipping to be safe, efficient, green, and intelligent.

On May 20 this year, the Pearl River Estuary Smart Aviation Insurance Service Demonstration Zone was approved to become the International Hydrographic Organization S-100 international sea trial zone, marking an important breakthrough in China's promotion of S-100 application. The Pearl River Estuary is one of the busiest sea areas with the busiest shipping and the most complex navigation environment in the world, making it an ideal testing ground for sea trials. The South China Sea Navigation Support Center has organized 60 ships to complete a total of 63 voyages of actual ship testing.

For the sea trial held on the 16th, the "Greater Bay Area No. 2" cruise ship was selected for the first time for actual testing. It departed from the Shekou cruise home port and passed through the Longgu West Channel, White Dolphin Island, and the Hong Kong-Zhuhai-Macao Bridge. The voyage took about 3 hours. This actual test focused on testing the service efficiency and user experience in a real navigation environment. Through the new generation S-100 slipway equipment, 10 types of data products, including S-124 navigation warnings, S-127 navigation rules, and S-102 high-density water depth, were tested, with 74 items covering 12 typical navigation scenarios. The test results show that these 10 categories of products meet expectations in terms of accuracy, currentness, usability and practical application value.
