RO-RO ships are vessels designed to carry wheeled cargo, such as cars, trucks, semi-trailer trucks, 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. RO-RO vessels have either built-in or shore-based ramps that allow the cargo to be efficiently rolled on and off the vessel when in port. Crown Navigation Co. (Pvt.)
