Core Viewpoint - The Heilongjiang Provincial Maritime Bureau has issued a safety warning regarding the upcoming ice formation period in major rivers, emphasizing the need for preparedness and safety measures for water traffic during this transitional phase [1][4][5]. Group 1: Weather and Ice Formation Predictions - Meteorological forecasts indicate that from late October to mid-November, the average temperature in Heilongjiang will be close to the historical average, approximately 1-1.5 degrees Celsius higher than in 2023 and 1-1.5 degrees Celsius lower than in 2024 [4]. - The expected ice formation dates for major rivers are as follows: - Heilong River (Heihe to Luobei): November 3-6 - Songhua River (Tangyuan to Tongjiang): November 18-20 - Ussuri River (Hulin to Raohe): November 16-20 - Nen River (Qiqihar to Tailai): November 15-20 - Complete freezing of all major rivers is anticipated by November 26 [4]. Group 2: Safety Risks During Ice Formation - The autumn ice formation period poses multiple threats to water traffic safety, including: - Ice impacts can damage vessels, with large floating ice blocks potentially causing hull damage or steering failures, leading to sinking risks [5]. - Ice accumulation can hinder vessel maneuverability, increasing draft and resistance, making navigation significantly more challenging [5]. Group 3: Safety Measures and Recommendations - The Heilongjiang Maritime Bureau has issued safety recommendations for vessel operators, urging them to take proactive measures to ensure water traffic safety and prepare for ice conditions [5][6]. - Construction and management units of water-related projects are advised to establish and improve emergency response plans for the ice formation period, including the preparation of emergency vessels and sufficient rescue equipment [6]. - Citizens are warned against walking, fishing, or working on ice-covered river surfaces due to unstable load-bearing capacity, and are advised to stay away from dangerous areas such as vessel mooring zones and river bends [7].
