An existing port in the Caspian Sea is being enlarged. For this purpose two large breakwaters are built to be able to enlarge the port. Both breakwaters have a length of over 1 km, and is built using Xbloc armour units.

2D model testing has been carried out at the laboratory of Delta Marine Consultants in Utrecht, The Netherlands.
