世界最大抓斗挖泥船现身广西北部湾海域

Core Viewpoint - The world's largest grab dredger "Jin Guang" has been deployed in the Beibu Gulf of Guangxi to support the construction of the 300,000-ton navigation channel expansion project at Fangcheng Port, marking a new phase of efficient progress in the project [1][4]. Group 1: Dredger Specifications and Advantages - "Jin Guang" is equipped with two large hydraulic grabs of 200 cubic meters and 136 cubic meters, with a maximum lifting capacity of 690 tons, emphasizing its efficiency in excavation and ecological protection [1][3]. - The 136 cubic meter hydraulic grab can directly excavate strongly weathered rock, replacing traditional blasting methods, thus minimizing ecological disturbances during the dredging process [1][3]. - The dredger features an integrated "environmental protection device" that acts like a precision filter to isolate dredged materials, significantly reducing their impact on the marine environment [1][3]. Group 2: Construction Efficiency and Techniques - The dredger can fill a 2,000 cubic meter mud barge in just 40 minutes, greatly enhancing construction efficiency compared to traditional vessels, which will shorten the overall project timeline [3]. - "Jin Guang" employs a steel pile anchoring method that requires only one-twentieth of the water area needed by traditional grab dredgers, allowing for seamless construction alongside ongoing navigation [3]. - The dredger's ability to autonomously move short distances enhances its maneuverability, enabling it to operate effectively in areas with significant tidal variations [3]. Group 3: Strategic Importance of the Project - The expansion project at Fangcheng Port is a key initiative for the Beibu Gulf International Gateway Port and the Western Land-Sea New Corridor, aiming to accommodate 300,000-ton vessels and establish an efficient maritime transport route [4]. - Upon completion, the project will enhance the regional competitiveness of the Beibu Gulf International Gateway Port and strengthen Fangcheng Port's role as a hub for bulk cargo transshipment [4].
