Constantza is located on the Western coast of the Black Sea, at 179 nM from the Bosphorus Strait and 85 nM from the Sulina Branch, through which the Danube flows into the sea. It covers 3,926 ha of which 1,313 ha is land and the rest of 2,613 ha is water. The two breakwaters located northwards and southwards shelter the port, creating the safest conditions for port activities. The present length of the North breakwater is 8,344 m and the South breakwater is 5,560 m. Constantza Port has a handling capacity of over 100 million tons per year and 156 berths, of which 140 berths are operational. The total quay length is 29.83 km, and the depths range between 8 and 19 meters, allowing the accommodation of tankers with capacity of 165,000 dwt and bulkcarriers of 220,000 dwt.
Constantza Port is both a maritime and a river port. Facilities offered by the port allow accommodation of any type of river vessel. The connection of the port with the Danube river is made through the Danube-Black Sea Canal, which represents one of the main strengths of Constantza Port. Due to low costs and important cargo volumes that can be carried, the Danube is one of the most advantageous modes of transport, an efficient alternative to the European rail and road congested transport. Important cargo quantities are carried by river, between Constantza and Central and Eastern European countries, such as Moldova, Bulgaria, Serbia, Austria, Slovakia and Germany.
