Development of the detailed engineering of the breakwater for the new port of Açu, which will become the third largest in the world, in an area where 85% of the country's oil and gas is produced.

The new dock, almost 2.5 km long, is made up of two types, one on a slope, some 600 m long, protected by 3.9 m³ Core-locs, and the other vertical with reinforced concrete caissons anchored between -15 and -26 m above sea level. Three berthing platforms are attached to the caisson dock, one 21 m deep and two 26 m deep. The first ten caissons were manufactured in Algeciras (Spain) and transported in semi-submersible vessels to provide temporary shelter for the two floating docks for the manufacture of the rest.
