RORO shipping, or roll-on-roll-off shipping, is a safe and reliable method used in the shipping industry to transport vehicles, equipment, and cargo overseas. RORO vessels are specifically designed with ramps and parking areas to facilitate the easy loading and unloading of cars, trucks, buses, and other rolling cargo. Unlike container shipping, RORO vessels allow vehicles to be driven or towed directly onto the ship using rolltrailers. This method is considered the safest and most cost-effective way to transport heavy equipment due to its simplicity and efficiency. Various industries, including automotive, mining, and construction, rely on RORO shipping to transport vehicles, machinery, and oversized cargo. Additionally, RORO shipping is ideal for project cargo and emergency vehicle transportation, providing a quick and efficient solution for delivering equipment and supplies to areas affected by natural disasters.
The use of RORO vessels in shipping offers several advantages:
Time Efficiency: RORO vessel is known for its time efficiency. The process of driving or towing vehicles directly onto the vessel is faster compared to the time-consuming process of loading and unloading vehicles into containers. This results in quicker turnaround times, reducing overall transit times.
Cost Efficiency: RORO shipping is often more cost-effective compared to container shipping. The cost of RORO transportation is typically lower than the cost of using individual containers, making it an economical choice for transporting vehicles and rolling cargo.
Reduced Risk of Damage: One of the significant advantages of RORO vessel is the reduced risk of damage to vehicles and cargo. With vehicles being driven or towed onto the vessel, there is minimal handling and lifting involved, reducing the chances of accidents or damage during loading and unloading. This makes RORO shipping a safer option for transporting vehicles and helps maintain their condition.
Ease of Loading and Unloading: RORO vessels are designed with dedicated ramps and parking areas, making the loading and unloading process efficient and straightforward. Vehicles can be easily rolled on and off the ship using rolltrailers, eliminating the need for complex lifting equipment or cranes.
Lashing equipment is an essential component of securing cargo on a RORO vessel. Here are some common types of lashing equipment used on RORO vessels:
Lashing equipment for RORO vessels includes various components, with lashing points and D rings serving as important deck fittings. Let’s explore their roles:
Lashing Point: Lashing points are fixed structures on the deck or within the vessel that are specifically designed to serve as secure attachment points for lashing cargo. These points are reinforced and strategically positioned to ensure proper distribution and securement of cargo during transportation. Lashing points are robust and reliable, providing strong anchor points for attaching lashing equipment and securing the cargo in place.
D Ring: D rings are metal rings shaped like the letter “D” that are affixed to the deck or sidewalls of the vessel. They are an integral part of the deck fittings on RORO vessels. D rings act as additional lashing points for securing cargo and provide flexibility in attaching various types of lashing equipment such as chains or ropes. Their shape facilitates easy attachment and adjustment of the lashing equipment, contributing to the secure transportation of cargo.
Lashing equipment for RORO vessels includes various components that are crucial for securing cargo during transportation. Two important pieces of lashing equipment are lashing turnbuckles and lashing chains:
Lashing Turnbuckle: Lashing turnbuckles are adjustable tensioning devices used to tighten and secure lashing chains or ropes. They consist of a threaded rod with a hook at each end. Lashing turnbuckles are employed to create tension and maintain the stability of the cargo. By adjusting the turnbuckles, the tension of the lashing chains or ropes can be easily modified as needed during the voyage. This flexibility ensures that the cargo remains securely fastened throughout the journey.
Lashing Chain: Lashing chains are heavy-duty chains specifically designed to withstand high forces and secure cargo on RORO vessels. They play a crucial role in connecting the cargo to the lashing points, providing strength and stability during transit. Lashing chains are often equipped with hooks or connectors at each end, allowing for easy attachment and securing. These chains are constructed to endure the rigors of transportation, ensuring the cargo remains firmly in place throughout the voyage.
Speed lashing, trailer chocks, trailer horses, and trailer jacks are essential equipment used in RORO vessels to ensure the safe and efficient transport of cargo. Let’s explore each of these components:
Speed lashing refers to a fast and effective method of securing cargo on RORO vessels. It involves using specialized lashing equipment, such as lashing turnbuckles and lashing chains, to quickly and securely fasten the cargo in place. Speed lashing techniques are designed to save time during loading and unloading operations while ensuring that the cargo remains stable and protected throughout the voyage.
Trailer chocks are devices employed to prevent trucks or trailers from moving during transport. These wedge-shaped blocks are placed behind the wheels of the trailer to immobilize it and prevent rolling or shifting. Trailer chocks add an extra layer of security and stability, ensuring that the trailer remains securely positioned on the vessel’s deck during transit.
Trailer horses, also known as trailer supports, are structures specifically designed to bear the weight of trailers and provide stability during transport. They are used to secure trailers on the vessel’s deck, preventing movement and maintaining the overall balance of the cargo. Trailer horses are engineered to withstand the forces encountered at sea and ensure that the trailers are securely attached and remain in place throughout the journey.
Trailer jacks are mechanical devices used to support the weight of trailers and assist in their secure attachment to the vessel’s deck. They provide lifting and stabilizing capabilities, facilitating the positioning and securing of the trailer during loading and unloading operations. Trailer jacks help maintain stability and enable the safe transportation of trailers on RORO vessels.
