The work involved the completion and renovation of the southern and northern breakwaters of the Port of Costanta. The project was financed by the European Investment Bank with EEC funds (PHARE Programme) and by the Romanian Government.

The repair operations consisted mainly of the construction of the following works:

• core with sorted quarry stone;
• berms at the foot of the breakwaters, with selected quarry material and 15 t Antifer cubes;
• armour protective layers made of selected quarry material, 7 t quarry blocks and 4.5 t and 25 t "Stabylopod" units;
• concrete wave-breaking crestwall.
• The total length of the two breakwaters is 12,850 m.
• The northern breakwater is 7,300 m long.
• The southern breakwater is 5,550 m long.

The rock material on the existing quays was removed with excavators, some installed on crane barges, transported by dumper trucks to a spoil area, then graded and stockpiled for future use.
