Like tankers which can be broken down into gas tankers oil tankers and chemical tankers there are a number of different types of dredger and these are categorized by their means of dredging. What are the different types of dredger vessels? In 4000 BC and not so long after the construction of the pyramids the branches of the River Nile and adjacent wharfs were thought to be constructed through use of dredging.Īnd fast forward to 1859 where dredgers were used to help construct the Suez Canal and then again to 1914 when the Panama Canal which relied hugely on dredgers was completed. In the French port of Marseille dredging is said to have been recorded from the third century BC and indeed the remains of a trio of dredgers were found on the harbor bed there. From as far back as 1000 BC harbors were rapidly being constructed in the Mediterranean with evidence of dredging being found. Not surprisingly as shipping and trade and commerce evolved dredging also had an important part to play. So why is dredging still used? That’s because in some situations there is no other perceived suitable alternative method.
