干散货船, or "bulk carriers," are specialized ships designed to transport unpackaged bulk cargo, such as coal, grain, and minerals. These vessels have large cargo holds that can accommodate significant quantities of materials, making them efficient for shipping raw goods across oceans. The design of 干散货船 allows for easy loading and unloading, often using cranes or conveyor systems. They play a crucial role in global trade, as they facilitate the movement of essential resources from producers to consumers, supporting industries and economies worldwide.
