![]() General Cargo, known as breakbulk, is usually on pallets or in bags. Smaller vessels can often discharge cargo directly into road vehicles. Cargo is usually unloaded into hopper barges, then transferred by conveyor to silos or open storage. When vessels unload using cranes and grabs, personnel and vehicles are often placed inside the holds to assist the process. Some bulk carriers are geared (usually a crane is located between each hatch) to allow the loading and unloading of cargo at berths without the need for shore equipment.įor unloading, cranes with grabs are the norm, although specialised equipment may be used for certain cargoes. In port, cargo is loaded by conveyor and spouts, or by crane and grab. These vessels are divided into several separate holds covered by hatches. ![]() Bulk Carriersįor dry cargoes with a high weight to cost ratio such as coal, grain and ore, economies of scale produced the modern bulk carrier. Such ships sometimes operated a regular service as liners between two or more ports, but could also operate in the “tramp trade” where vessels would go wherever they were required. Cargo would be stowed in different holds and the speed and effectiveness of the loading/unloading process would depend on the the ship’s crew and the port workers or “Stevedores”. Known as general cargo vessels, they would be equipped with their own cargo loading equipment, usually in the form of a derrick lifting device. Historically, dry cargo vessels were the the most common vessels in the world’s merchant fleet.
