Roll on Roll off ( RO/RO) shipping
The roll-on / roll-off ship is one of the most successful methods of shipping operating today. Its Price, flexibility, ability to integrate with other export systems and speed of operation have made it extremely popular on many shipping routes.
RO/RO vessels have built-in ramps which allow the cargo to be efficiently rolled on and rolled off the vessel when in port. While smaller ferries that operate across rivers and other short distances still often have built-in ramps, the term RORO is generally reserved for larger ocean-going vessels. The ramps and doors may be stern-only, or bow and stern for quick loading.
One of the ro-ro shipments most important roles is as a passenger/car ferry, particularly on short-sea routes.The modern roll-on/roll-off ship can trace its origins back more than one hundred years to the early days of the steam train. Ro-ro ships also integrate well with other shipping methods, such as containers, and the use of Customs-sealed units has enabled frontiers to be crossed with the minimum of delay, thereby further increasing speed and efficiency for the shipper.
