What is the difference between a car carrier and a RoRo?

The primary difference between a car carrier and a RoRo (Roll-on/Roll-off) ship lies in their cargo capacity and design. While a car carrier is specifically designed to transport vehicles like cars, vans, and trucks, a RoRo ship can carry a mix of vehicles and freight. Additionally, some vehicle carriers, such as those operated by Grimaldi Lines, can also transport containers, showcasing a broader range of cargo versatility.

Understanding the difference between a car carrier and a RoRo ship is key in the logistics and transportation industry. A car carrier is purpose-built to transport vehicles such as cars, vans, and lorries, focusing solely on vehicle transport. In contrast, RoRo ships have a more versatile design, allowing them to carry vehicles and various freight types. This distinction is crucial in planning and executing vehicles and goods maritime transport. This article will delve deeper into the specific features and functions of both car carriers and RoRo ships, highlighting how their designs cater to different transportation needs.

Defining RoRo Ships

RoRo ships, abbreviated from roll-on/roll-off ships, are vessels specifically designed for wheeled cargo such as cars, trucks, and trailers, among others. This type of cargo is driven on and off the ship on their wheels or using a platform vehicle. Unique to RoRo ships is the built-in ramp, which can be clamshell doors, stern ramp, or side ramp, allowing cargo to be efficiently “rolled on” at the origin and “rolled off” at the destination point.

The structure of a RoRo ship is primarily influenced by its function – the transportation of wheeled cargo. To accommodate this, the decks are designed to be open and unobstructed, optimizing space for the cargo. The hull of the RoRo ships is typically box-shaped, ensuring maximum carrying capacity. Moreover, they are also characterized by large doors at the stern or bow and occasionally on the sides, enabling easy loading and unloading of cargo. The ship is installed with internal ramps and elevators to move vehicles between decks during the voyage.

The Design and Structure of Car Carriers

Car carriers, primarily known for their unique design, are structured specifically to cater to the needs of vehicle transportation, making them distinct from other types of cargo ships. The common design structure includes large side-ramps for loading and unloading purposes, multiple decks for vehicle storage and accommodation, and a distinctive box-like shape. Designed with maximum space utilization in mind, the decks could be adjusted according to the sizes and types of vehicles loaded. The loading process generally begins from the uppermost deck, filling downwards to optimize balance, stability, and efficiency.

Notably, car carriers are also equipped with various safety measures due to the nature of the cargo being transported. State-of-the-art fire detection and suppression systems are installed to mitigate the risk of fire-related damages. Adequate ventilation systems are also in place to prevent the accumulation of potentially harmful exhaust gases from the vehicles. Furthermore, the design and structure of these ships also contribute to their seaworthiness and stability, ensuring safe and efficient transportation of vehicles even under unfavorable marine conditions.
