Cargo, or container ships as they are sometimes called, are an intricate part of transporting goods around the world.
Did you know, these massive container ships are actually fairly new and have only been in operation for the past 60 odd years? In fact, the first container ship set sail out of Denmark in 1951.
And they continue to be a very important form of transport in the world today. Why? Well, container ships carry around 90% of the world's non-bulk cargo. Think about that number... it is simply incredible!
The cargo transported by these ships is divided into two types: bulk cargo and break bulk cargo.
Bulk cargo is transported in the hold of the ship in specially ventilated areas. This type of cargo includes grain, maize and other edible plants, for example.
Break bulk cargo is manufactured goods and generally transported in packages, for example boxes within a large container, packed tight to help stop breakages.
Of course, to get this cargo on board a container ship and to manipulate it while at sea requires a range of equipment. Not just cranes but locking mechanisms, ropes, nets and others. The cargo ship also has equipment that helps it complete its task in an efficient manner.
Let's see how many parts of this equipment you can guess from an image!
