Car Carrier Design and Build

A wonder of engineering, automobile carrier ships are built specifically to meet the demands of transporting wheeled cars. Car carriers require a special approach to loading and unloading as well as interior design, unlike conventional cargo ships. Let’s examine these features in further depth.

Loading and Unloading:  A Symphony of Ramps

The Need for Ramps:  While shipping containers are loaded and unloaded onto cargo or container ships using cranes or derricks, and chemicals are transferred using a system of pipes, car carriers require a different method. The key to their functionality lies in ramps.

Ramp Locations:  These ramps may be located at various strategic points on the vessel, including the stern (back), bow (front), or even the sides of the ship. The placement of ramps ensures smooth and efficient loading and unloading operations.

The Process:  The ramps allow the cargo, whether cars, trucks, or other vehicles, to be easily driven onto the ship and then off again at the destination port or terminal. This method minimizes handling and reduces the risk of damage to the vehicles.

Interior Design:  A Labyrinth of Decks and Ramps

Multiple Decks:  Car carriers are equipped with multiple decks to accommodate the large number of vehicles. These decks are often adjustable, allowing for customization based on the size and type of vehicles being transported.

Car Carrier Capacities

Car Carrier Capacities

A car carrier ship’s capacity, which determines how many automobiles it can carry at once, is an essential component of its operation. Car carriers have a special way of measuring capacity, unlike conventional cargo ships that use TEUs (Twenty-foot Equivalent Units). Now let us explore the complexity of automobile carrier capacity.

LiM:  Lanes in Meters, A Unique Measurement

Definition and Purpose:  Car carriers use a different standard of measurement known as LiM, or Lanes in Meters. Since the cargo is not in shipping containers but consists of cars, trucks, or other vehicles, a unique measurement standard is required.

Calculation of LiM:  To calculate the amount of cargo a car carrier can transport, the length and breadth of the lanes where the vehicles are placed are multiplied by the number of decks in the vessel. This calculation gives the LiM, representing the total lane meters available for vehicles.

Adaptation to Different Vehicle Types

Versatility in Design:  Car carriers are designed to accommodate various types of vehicles, from compact cars to large trucks and machinery. The adjustable decks and internal ramps provide the flexibility to optimize space for different vehicle sizes.

Maximizing Space Utilization:  The design and capacity measurement of car carriers allow for maximizing space utilization. By adjusting the decks and arranging vehicles efficiently, the ship can transport a large number of vehicles, optimizing profitability and sustainability.

Comparison with Traditional Cargo Measurements

TEU vs. LiM:  TEU, or Twenty-foot Equivalent Unit, is the unit used to measure the cargo capacity of conventional cargo ships, container boats, and container feeders. The volume of twenty-foot-long shipping containers is the basis for this measurement. However, the LiM measurement is more pertinent and useful since automobile carriers move vehicles rather than containers.

Tailored to Specific Needs:  The use of LiM as a measurement standard reflects the specialized nature of car carrier ships. It’s a tailored approach that considers the unique characteristics of the cargo, ensuring accurate and meaningful capacity measurement.
