On September 11th, the vessel 'Hai Xun 1506' docked at Dalian Port, marking the completion of the Dalian Navigation Mark Office's 2026 annual routine buoy replacement operations. This operation involved the replacement and maintenance of 57 navigation buoys in the sea area surrounding Dalian. Navigation buoys, essential aids for sea vessels, require regular maintenance due to exposure to harsh marine conditions, including air, seawater, and sea bird activities. The work included the timely replacement of buoys affecting visibility, position inspections of key buoy locations, and checks for anchor chain wear, achieving the objectives of accurate positioning, proper lighting, vibrant colors, and structural integrity, thereby ensuring safe navigation for vessels.
