Definition

A RO-RO (Roll On-Roll Off) ship is a type of cargo ship specially 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. This method allows for efficient handling of a wide variety of cargo types and significantly reduces docking times.

Examples

  1. Car Carriers: RO-RO ships are commonly used to transport newly manufactured cars from production plants to markets around the world.
  2. Trailer Transport: Companies might use RO-RO vessels to transport trailers loaded with goods, streamlining the transfer process between road and sea.
  3. Military Equipment: Armed forces use RO-RO ships to quickly deploy vehicles and machinery to operational locations.

FAQs

Q1: What distinguishes RO-RO ships from LO-LO (Lift On-Lift Off) ships? A1: Unlike LO-LO ships, which require cranes to lift cargo, RO-RO ships allow cargo to be driven directly onto and off the vessel. This reduces loading and unloading time and labor costs.

Q2: Do RO-RO ships accommodate non-wheeled cargo? A2: Yes, RO-RO ships can also carry non-wheeled cargo on modular flatbeds designed to be rolled on and off the ship.

Q3: What are the key benefits of using RO-RO ships? A3: Benefits include rapid loading/unloading, less manual labor, improved time efficiency, and better utilization of ship capacity.

Q4: Are there different types of RO-RO ships? A4: Yes, there are different types of RO-RO vessels, including PCC (Pure Car Carrier), PCTC (Pure Car and Truck Carrier), and RoPax (a combination of RO-RO and passenger ferry).

Q5: What is a RO-RO ferry? A5: A RO-RO ferry is a ship designed to transport both passengers and their vehicles across short distances, offering services where road networks may be interrupted by water bodies.

  • LO-LO (Lift On-Lift Off): A type of vessel where cargo is loaded and unloaded using cranes.
  • RoPax (Roll On-Roll Off and Passenger): Combines the features of a RO-RO cargo ship and a passenger ferry.
  • Self-Propelled Modular Transporter (SPMT): A platform vehicle used to transport large and heavy loads, often used in conjunction with RO-RO operations.
  • Car Carrier: A specialized RO-RO vessel designed specifically for the transport of vehicles.
