Roll-on/Roll-off (RoRo) is a method of transporting vehicles and cargo by ship. In this system, vehicles are driven directly onto the vessel using ramps, making loading and unloading efficient. RoRo ships are designed with built-in ramps that allow for easy access, which is particularly useful for transporting cars, trucks, and heavy machinery. This shipping method is commonly used in international trade, especially for transporting goods between continents. RoRo services are often faster and more cost-effective than traditional cargo shipping methods, as they reduce the need for cranes and other heavy equipment during loading and unloading processes.
