Question

why was the' Ro-Ro transport stand for?​

Answer 1

To begin with the definitions, RoRo stands for Roll-on/Roll-off, while LoLo stands for Lift-on/Lift-off. As loading methods, RoRo means workers drive cargo on and off ships, while LoLo means cranes are used to lift the cargo. RoLo also exists, combining the two as cargo is driven on and lifted off, but it’s more niche and case-specific than either.

Notably, however, the terms refer to both loading methods and vessels. RoRo ships typically come with ramps or slips that allow workers to drive wheeled cargo on and off them. Conversely, LoLo ships come with on-board cranes or similar handling equipment that let them handle cargo unassisted. For this reason, LoLo ships are also often called geared vessels.

As loading methods, both RoRo and LoLo have historically seen uses for a wheeled cargo of various types. While LoLo remained prominent for car transportation during the first half of the 20th century, RoRo became a viable alternative due to carrier advancements. Both are viable options today, with distinct advantages and disadvantages that address global trade challenges differently.

RoRo vessels

The aforementioned carrier advancements have yielded many different types of RoRo vessels over the years. By definition, RoRo vessels facilitate RoRo as a loading method to various degrees and meet specific transportation needs.

ConRo

ConRo vessels are hybrid ships, hence the name; they combine the features of RoRo and Container ships. Such vessels accommodate both containerized and unitized wheeled cargo, on deck and below-deck respectively. For the purpose of transporting automobiles, internal ramp systems keep cars separated from other vehicles.

RoPax

RoPax (roll-on/roll-off passenger) vessels are RoRo vessels that facilitate both wheeled cargo transportation and passenger accommodation. This term is mostly technical, however, as vessels with both a RoRo car deck and passenger facilities are often referred to as cruise ferries.
