Every year, around 25,000 sea ships arrive in our country, with a little more departing. The total weight of cargoes is approximately 118 millions of tons. In terms of unloading, the weight is even higher and amounts to some 140 millions of tons. These tonnages are significantly higher than those registered at the turn of the century. However, the number of arriving and departing ships is lower than then, which indicates that ships tend to carry heavier cargoes.
