What does the development of maritime transport all over the world depend on?

A fairly large number of goods all over the world are transported by sea. It has a lot of advantages, one of them, for example, the low cost of sea transportation in terms of the weight of the transported goods. Sea transport can improve its efficiency in two ways. This is a decrease in the cost of transportation and an increase in the speed of delivery of goods. Reducing the cost is possible by increasing the size of the vessel, which allows you to simultaneously carry more cargo, also by reducing the weight of the vessel. The cost can also be reduced by reducing fuel consumption, this is helped by changing the shape and improving the engine. All these factors also affect the speed of delivery of goods – the shape of the vessel, modern engine, etc.
