en.Wedoany.com Reported - Recently, the Three Gorges ship lock commenced a planned 45-day maintenance period, reducing the shipping capacity of the Yangtze River and causing delays for some vessels arriving at ports. Chongqing Iron and Steel, located along the Yangtze River, faced challenges in raw material supply. The company immediately activated its emergency supply guarantee plan, identified critical materials in short supply, adjusted transportation schemes, and established an emergency supply system primarily based on "rail + water" transport via the New Land-Sea Corridor.
Chongqing Iron and Steel reduced its reliance on waterway transport and quickly activated the combined "rail + water" raw material emergency route on the New Land-Sea Corridor. The team identified 15 safeguard measures covering the entire process of receiving, transshipment, and stockpiling. To prioritize raw materials transported via the New Land-Sea Corridor, the company suspended the delivery of non-essential containers to the plant, while other types of raw materials were scheduled for balanced arrival. In the loading and unloading area, the original daily unloading capacity of 160 containers was increased by adjusting the coordinated operation of reach stackers—two units working simultaneously, one unloading and the other returning empty containers, thus accelerating the work pace. Concurrently, the sampling process for containerized coal was optimized, boosting the unloading capacity to 200 containers per day.
An on-site dispatch supervisor stated: "Sufficient vehicles are allocated so that raw materials are immediately transferred to the stockyard after unloading." The storage layout of the rear stockyard was re-coordinated to make way for raw materials from the emergency channel. The general contractor arranged dedicated personnel to work on-site, coordinating the return of empty containers and vehicle queuing issues at the receiving site. Dedicated staff liaised with the railway department to track the empty container return plan. An on-site coordinator recalled: "We had to keep a close eye on the location of every container and the schedule of every train."
During the 45-day maintenance period, Chongqing Iron and Steel received 124,900 tons of raw materials via containers through the New Land-Sea Corridor, ensuring the continuous operation of its production lines. Chongqing Iron and Steel will summarize the experience from this emergency supply guarantee, optimize logistics and transportation plans, improve a multi-channel, multi-modal transportation guarantee system, and continuously enhance the stability of multimodal transport.
