Roll-on/roll-off (RORO or ro-ro) ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, trailers, and railroad cars, that are driven on and off the ship on their own wheels or using a platform vehicle, such as a self-propelled modular transporter.
A RORO ship, also known as a roll-on roll-off ship, is a type of freight or ferry vessel that is specifically designed to transport vehicles, such as cars, trucks, trailers, and all-wheeled cargo. The name “roll-on roll-off” refers to the method of loading and unloading the ship, where the vehicles drive on and off the ship via ramps.
These ships are equipped with large openings at the bow and stern, sometimes in the side, which allows for rapid loading and discharge of vehicles and other cargo. The ramps used to load and unload the cargo are typically hydraulically operated, providing easy access for vehicles to drive on and off the ship.
As said before, RORO ships are commonly used to transport vehicles and other wheeled cargo across the ocean, but they are also used for shorter ferry routes, such as between islands or across rivers.
RORO ships are considered the most efficient way of transportation for wheeled cargo, they save a lot of time and resources compared to traditional cargo ships, and they are also more environmentally friendly.
