We all are pretty much aware of the concept of "Ship within a ship" followed in the late 1800s. It was one of the craziest things ever made to enforce the class system. The kind of service provided to the passengers was according to the amount of money paid by them for travelling in first, second or third class. We have witnessed it in the movies like Titanic.
But what if I tell you that such a ship exists even today. Yeah, it has not been damaged till date. The only question remains is that "What is the purpose of creating such a machine?"
It is a heavy lift ship which is carrying another ship in it.
Just imagine the size of a ship carrying an entire oil rig.
A heavy ship can carry as many as 12 carrier ships in it.
