55米级货船首“穿”蜀山船闸，杭甬运河宁波段通航实现新突破

Core Viewpoint - The successful passage of the cargo ship "浙余杭货03102" through the Shushan Ship Lock marks a significant increase in the navigation capacity of the Hangzhou-Ningbo Canal, following a policy adjustment that allows larger vessels to transit through the lock [1][2][5]. Group 1: Navigation Capacity Enhancement - The Shushan Ship Lock has officially raised the maximum dimensions for vessels, now allowing ships up to 55 meters in length and 2.4 meters in draft, compared to the previous limits of 45 meters and 2.2 meters [5]. - This adjustment is a response to the growing demand for inland shipping and aims to improve logistics efficiency along the canal [6]. Group 2: Economic Impact - The new regulations are expected to significantly reduce logistics costs; for instance, a logistics company estimates that using larger vessels will decrease the number of trips needed from 660 to 420, saving approximately 800,000 yuan annually [8]. - Since the full opening of the Hangzhou-Ningbo Canal in 2013, the total cargo volume has exceeded 35 million tons, indicating the canal's importance in regional logistics [8]. Group 3: Strategic Importance - The Hangzhou-Ningbo Canal is a crucial part of the national high-grade waterway network and serves as an important transport channel for the Ningbo-Zhoushan Port, facilitating sea-river intermodal transport [6]. - The enhancement of the Shushan Ship Lock's capacity is a key initiative in the "Shipping Zhejiang" development plan and supports the high-quality development of inland shipping in Zhejiang province [8].
