此次关洲水道应急疏浚工程完工后，通过优化调整航标，可将航宽提升至210米，保障宜昌中水门至松 滋跨宝山航段枯水期4.5米水深稳定运行。 中新网宜昌12月19日电 (记者 郭晓莹)记者19日从长江宜昌航道局、长江荆州航道处获悉，长江中游宜 昌段关洲水道应急维护疏浚工程、荆州段陡湖堤水道应急抢通疏浚工程均于近期完工，航宽显著提升， 通航条件得到改善。 关洲水道上至石灰窑，下至跨宝山，全长10.9千米。该水道属弯曲分汊河型，浅区航宽有限，制约航道 通过能力，且给船舶航行带来安全隐患。此前，航道部门已对关洲边滩浅区实施养护疏浚，推动局部航 道条件显著改善，但航段弯曲、浅点残留等问题仍未彻底解决，枯水期水深保障压力依然突出。 为彻底解决这一长期存在的航行安全隐患，长江荆州航道处启动陡湖堤水道应急抢通疏浚项目。经过专 项施工，该水域碍航乱石现已全部清除，枯水期适航宽度由不足150米拓宽至约200米，航道通航能力大 幅提升。(完) 陡湖堤水道杨公堤区域位于荆江中段，沿线码头分布密集，通航环境复杂，水下暗藏的乱石堆侵占下行 航道，对过往船舶安全航行构成较大威胁。近年来，受荆江河床下切、枯水期水位下降及船舶大型化趋 势等多重因 ...

Core Insights - The article highlights the launch of the "Taihu Light," an eco-friendly intelligent integrated dredging platform designed by China Communications Tianjin Navigation Bureau, which will be deployed for ecological dredging in Taihu Lake [1][2] - The platform aims to complete over 10 million cubic meters of dredging tasks in the next six years, equivalent to reducing nearly 4,000 standard swimming pools' worth of sediment from Taihu Lake [1] Company Overview - The "Taihu Light" is a mobile ecological factory specifically tailored for Taihu Lake, addressing traditional dredging challenges such as large land occupation and poor adaptability [1] - The platform consists of five vessels, including the "Taihu Dredging No. 2," "Taihu Light No. 1," "Taihu Light No. 2," "Taihu Light No. 3," and a residual water treatment vessel, creating an ecological closed-loop system for dredging, screening, dewatering, and water purification [1][2] Technological Advancements - The residual water treatment vessel can stabilize water quality to meet Class III surface water standards, allowing for direct discharge into the lake [2] - The platform employs a smart construction system utilizing big data analysis and AI models for real-time monitoring and control, achieving a daily dredging capacity of 8,000 cubic meters [2] - The platform operates on clean shore power, resulting in zero oil consumption during operations, and the dredged sludge can be repurposed for wetland restoration and mine reclamation [2] Environmental Impact - In 2024, Taihu Lake is expected to achieve a historic breakthrough, with its water quality improving to Class III for the first time in 30 years [2] - However, the presence of nutrient-rich sediment accumulated over decades remains a significant challenge to the sustained improvement of water quality [2]

Core Viewpoint - The project is a maintenance dredging operation in the inland waterways of Shanghai, specifically in the Songjiang District, aimed at enhancing navigation capacity and safety while optimizing ecological benefits [2][5]. Group 1: Project Overview - The dredging project spans a total length of 5.93 kilometers with a total volume of 101,300 cubic meters, primarily focused on removing sediment from the waterway [2]. - The North Maojing waterway has a unique geographical position and is classified as a Grade VII technical level, necessitating precise design standards to accommodate small vessel traffic [2]. Group 2: Construction Challenges and Solutions - The construction area has a dense network of underground pipelines, increasing the complexity and risk of the dredging operation [4]. - A specialized pipeline inspection team was established to conduct thorough surveys of underground pipelines, ensuring zero accidents during construction [4]. - The project team adopted self-propelled backhoe dredgers and dynamically adjusted vessel ratios to optimize the workflow, resulting in a 30-day reduction in the overall construction period [4]. Group 3: Environmental and Community Considerations - To minimize noise and pollution, the project team implemented reasonable work hour arrangements and reduced nighttime construction activities, thereby lessening the impact on local residents [4]. - An effective communication mechanism was established, including multiple coordination meetings and visits to local residents, ensuring a smooth feedback channel with the government [4]. Group 4: Project Outcomes - The completion of the project significantly improved the navigation capacity and safety of the North Maojing waterway, while also enhancing the ecological environment [5]. - The project serves as a model for Shanghai's green shipping development and high-level water environment management [5].

Core Viewpoint - The article highlights the operational capabilities and significance of the Chinese dredging vessel "Xin Hai Feng" in the expansion project of Port Klang, Malaysia, emphasizing its advanced technology and contribution to local development [1][2][3] Group 1: Vessel Operations - The "Xin Hai Feng" is a large dredging vessel with a capacity of over 16,000 cubic meters, capable of handling 100 cubic meters of seabed sand per minute, and can fill its hold in about two hours [2] - The vessel operates 24 hours a day, alternating between sand extraction during the day and dredging at night, showcasing its efficiency and continuous operation [1][2] - The vessel's construction precision can reach centimeter-level, enabled by advanced intelligent dredging systems that allow for single-operator control [2] Group 2: Project Significance - The expansion of Port Klang's West Port is crucial as it will double the container throughput capacity, reinforcing its role as a key logistics hub for Malaysia's international trade [3] - The project not only employs local Malaysian workers but also fosters good relationships with surrounding communities, highlighting the collaborative nature of the China-Malaysia partnership [3] - The introduction of advanced technology by Chinese enterprises is expected to accelerate project progress and contribute to Malaysia's development [3]
