Core Viewpoint - The maritime safety and navigation efficiency are prioritized as the Hainan Free Trade Port approaches its closure, with various measures being implemented to support this transition [2]. Group 1: Navigation Safety Measures - The Nanhai Navigation Guarantee Center has introduced a series of initiatives to enhance navigation safety and efficiency in Hainan's waters, particularly in light of the upcoming closure of the free trade port [2]. - A total of 73 navigation marks have been adjusted and deployed to support the operation of a 150,000-ton berth at Yangpu Port, laying the groundwork for the construction of a 200,000-ton berth and "two-way navigation" [2]. - The Hai Kou Navigation Mark Office has successfully completed the adjustment and establishment of navigation marks for over 20 locations, optimizing the distribution of key waterway navigation marks [2]. Group 2: Communication Enhancements - The Hai Kou Communication Center has improved the layout of maritime communication stations to meet the operational requirements of the Hainan Free Trade Port, significantly enhancing communication reliability and reducing signal blind spots [3]. - New high-frequency communication circuits have been added to the Sanya coastal radio station, extending communication range from approximately 200 kilometers to 900 kilometers, ensuring communication support for vessels post-closure [3]. Group 3: Digital Transformation in Maritime Services - The Guangzhou Maritime Surveying and Mapping Center has conducted extensive port channel mapping, covering over 1,300 square kilometers annually, and has implemented high-frequency updates for key ports [3]. - The center is advancing the digital transformation of the maritime system by developing new digital navigation safety service products, which have begun to establish a "data-driven, intelligent collaboration" ecosystem for maritime safety [3]. - Future initiatives will focus on enhancing the coverage of intelligent navigation marks and extending wireless broadband networks to offshore areas, while also promoting information sharing with customs and maritime police [4].
