Roll-on/roll-off (Ro-Ro) ships are enclosed maritime vessels that transport vehicles from one port to another. Unlike open-air container ships, they keep cars inside with sophisticated ventilation, security and stabilization systems.

If you need to safely ship your vehicle over water, Ro-Ro shipping may be your more efficient and cost-effective option.

What Is a Roll-On/Roll-Off Ship, and Why Is It Unique?

Roll-on/roll-off ships are designed with rolling loads in mind. Instead of loading cars into containers and lifting them with cranes, known as lift-on lift-off, workers can simply drive vehicles onboard the Ro-Ro ship and secure them in place. Inside, cars are safe from weather fluctuations while the ship completes its journey.

Each ship has one or more heavy-duty hydraulic ramps that professional drivers use to move vehicles from the dock’s paved working area or apron to the deck. Ramps can often adjust to accommodate different port heights, tidal conditions and the ship’s movement.

Many Ro-Ro ships feature multiple decks connected by internal ramps like a massive floating multistorey parking garage. Crew can adjust the decks’ heights to fit the specific number and type of vehicles awaiting transport. Drivers can easily maneuver vehicles throughout the ship using these adjustable decks and ramps.

How Does Roll-On/Roll-Off Car Shipping Work?

Vehicles begin their journey at the departure port. From there, they go through inspection, loading, securing and transportation before safely arriving at their destination port. Each of the following steps requires great care to keep the cars in excellent condition:

  1. Inspectors document the car’s initial condition: Before cars drive onto the ship, inspectors meticulously document every scratch, dent or mark. Some even use AI software to render detailed 3D models of each vehicle. This data lets workers accurately track each car’s condition mid-voyage and carefully monitor their safety.
  2. Drivers load cars onto the ship via the ramp: Traffic control systems and marked lanes guide drivers through loading, helping ensure cars sit a safe distance apart. Some newer Ro-Ro vessels use software to plan each car’s placement and guide drivers along their route for optimal weight distribution and stability.
  3. The ship’s crew secures vehicles with straps and braces: Trained crewmembers then secure each vehicle enough to withstand even the choppiest ocean conditions. Crews use wheel chocks, straps and electronic tension monitors to fix each car in place before setting sail.
  4. Drivers carefully unload cars at the destination port: Once the roll-on/roll-off ship docks in its destination port, employees begin the unloading process. Vehicles move in a coordinated sequence from ship to shore toward designated processing areas for inspection and distribution.

What Are the Advantages of Roll-On/Roll-Off Shipping?

Transporting Cars on a Ship.

Transporting your car in a Ro-Ro shipment comes with many benefits, including the following:

  • Fast, efficient loading and unloading: Vehicles board and disembark Ro-Ro ships swiftly and smartly, especially compared to container ships that need each car lifted and carefully positioned with a crane. This benefit gives Ro-Ro shipping faster turnaround times
  • Diverse vehicle accommodation: A single Ro-Ro vessel can transport up to 8,000 cars simultaneously using its multilevel adjustable deck. It can also take on different vehicle types, from cars to construction equipment.
  • Cost-effective long-distance shipping: The more vehicles that can share the journey, the lower the cost per unit. This streamlined system and superior efficiency make roll-on/roll-off ships a wise financial choice.
  • Cars stay in pristine condition: Ro-Ro vessels keep vehicles safe using temperature and humidity control, salt air protection, UV shielding, vibration dampening and air filtration. These help vehicles arrive in the same condition throughout travel.

What Are the Challenges of Roll-On/Roll-Off Shipping?

Shipping roll-on/roll-off loads come with a handful of challenges, including:

  • Limited space: Unlike container ships that simply stack same-sized blocks on the upper deck, Ro-Ro shipping requires optimized systems run by highly trained workers to best fit all the differently shaped and sized vehicles onboard safely.
  • Destination limitations based on infrastructure: Ro-Ro ships need specific port facilities to operate safely, including floating platforms, reinforced docking areas and aprons, large vehicle storage spaces, bollards that secure vessels and trained personnel. The port’s ramp systems must match different ship ramp designs and allow safe loading angles for all ship types and tides.
  • Weather-related delays: Harsh weather conditions, particularly wind, can pose significant challenges when loading vehicles onto a roll-on/roll-off ship. Many modern ships use weather modeling, positioning systems and ramp stabilization technology to safely minimize delays.

Which Vehicle Types Can Go on a Ro-Ro Shipment?

Roll-on/roll-off ships can transport virtually anything on wheels, from small personal vehicles to massive industrial equipment. There are various types of Ro-Ro ships, each best suited to different customer needs and preferences.

Container Roll-On/Roll-Off Vessels (Con-Ro)

Con-Ro ships offer an impressive carrying capacity, combining container storage on upper decks with vehicle decks below. These versatile carriers handle standard shipping containers alongside commercial trucks, construction machinery, agricultural equipment and industrial vehicles on rolling platforms.

Pure Car Carriers (PCC)

PCCs feature multiple decks exclusively for automobiles, with medium to large capacity. They primarily transport new passenger vehicles, luxury and electric cars, smaller vehicles like motorcycles, rental fleets, classic automobiles and small commercial vans. Vehicles need proper preparation for transport, including functional brakes, specific fuel levels and deactivated alarms.

Pure Car and Truck Carriers (PCTC)

PCTCs are enhanced versions of PCCs with higher decks and stronger ramps, offering larger capacity for diverse vehicle types. They accommodate standard cars, larger haulers like semi-trucks, transit buses, recreation vehicles (RVs) like motorhomes and campervans, construction equipment like excavators and bulldozers, agricultural machinery, military vehicles and emergency response units.

Roll-On/Roll-Off Passenger (Ro-Pax) Vessel

Ro-Pax vessels, or car ferries, combine vehicle transport with passenger service on shorter routes. Despite having the smallest vehicle capacity, they efficiently handle personal cars, tourist coaches, delivery vans, motorcycles, bicycles and camping vehicles while providing passenger accommodations. They’re essential for coastal and inter-island transportation.

 

How Do Ro-Ro Shipping Rates Compare to Alternative Transport Methods?

Each cross-country vehicle transport method offers distinct advantages, balancing cost, speed, protection and accessibility to serve different needs in the global logistics chain

Roll-On/Roll-Off Shipping

Ro-Ro shipping can be a highly economical maritime option for United States ports. They excel most along shipping routes where multiple vehicles need transport. This method keeps costs low through efficient loading processes and minimal handling requirements, reducing insurance rates. Ro-Ro shipping effectively serves commercial and private customers, offering reliable transportation for most vehicle types.

Rates vary among Ro-Ro vessel types based on their features. PCCs offer the most competitive rates for standard vehicles, while PCTCs command higher rates due to their reinforced decks and unique handling equipment. Con-Ro vessels typically charge premium rates as they combine container and vehicle capabilities.

Container Shipping

In the United States, container shipping costs can often exceed that of Ro-Ro, with prices varying significantly between shared and exclusive containers. Workers must load vehicles into containers and take them out at loading stations, known as “stuffing and stripping.” The containers must then wait for crane availability at each port, adding time and complexity.

Air Carriage

Air carriage is excellent for time-critical deliveries. However, shipping heavy loads by air carrier costs more than by sea, making it practical only when you need immediate delivery. While it offers the fastest shipping times, air carriage’s limited vehicle capacity and high expenses restrict its use to exceptional circumstances.

Auto Transport Services

Auto transport services provide the standard solution for domestic and regional vehicle movement, particularly for distances under 500 miles. These services combine cost-effectiveness with door-to-door delivery options and flexible scheduling throughout inland areas. Auto transport carriers deliver reliable service across established networks for single vehicles and locations away from ports.
