Securing vehicles on a Ro-Ro cargo ship is a meticulous process designed to ensure their safety during transit. The vehicles are carefully positioned in designated parking areas on the cargo decks.

Securing operations should be completed before the ship proceeds to sea. This is crucial to prevent any potential disasters that could occur due to instability.

Persons appointed to carry out the task of securing vehicles should be trained in the use of the equipment to be used and in the most effective methods for securing different types of vehicles. This training is essential to ensure that the vehicles are properly secured.

Securing vehicles involves using a combination of wheel chocks, lashings, and chains. Wheel chocks are placed around the tires to keep the vehicles stationary, while lashings are attached to anchor points on the ship's deck and the vehicle's chassis or wheels.

Here's a summary of the primary securing methods:

The ship's crew conducts thorough inspections to ensure all lashings and chocks are properly applied and tight. They also regularly monitor the secured vehicles throughout the voyage to address any issues that may arise due to shifting sea conditions.

RoRo ships first appeared in the 19th century, specifically in 1851, with the Firth of Forth ferry being one of the earliest examples.

The first RoRo ships were used to transport railway cars and carriages, which were too wide for bridges, by taking them across rivers instead.

The RoRo principle was later used in tank landing craft during World War II, where amphibious vehicles landed tanks on beaches, such as on D-Day.

In the late 1940s, merchant ships began benefiting from the RoRo principle, especially on short ferry crossings as motor cars and other vehicles became more popular.
