ACCIONA Construction takes part in a conference on reinforced concrete floating caissons


The event was organised by the Young Professionals Committee of the Technical Association of Ports and Coasts.

ACCIONA Construction took part in the conference on reinforced concrete floating caissons, organised by the Young Professionals Committee of the Technical Association of Ports and Coasts (ATPYC) on 31 May at the headquarters of Puertos del Estado.

 Domingo Antonio González Suárez from ACCIONA Construction gave a talk about the construction processes used in manufacturing these types of structures. 

 He analysed all of the elements involved in the process, including personnel, machinery and materials, and outlined the different techniques that can be used to construct these structures, both at sea (on semi-submersible pontoons, suspended platforms, floating docks or using caisson-building floating docks) and on land (in a dry dock or on a dock side or esplanade). 

Domingo Antonio González also explained the differences between the construction techniques used in Spain and those used in other parts of the world. 

While caisson-building floating docks and semi-submersible pontoons are commonly used in Spain, producing rectangular caissons with square or circular cells, the most commonly used techniques internationally are land-based, producing different types of caisson depending on the country.

 ACCIONA is a leader in constructing reinforced concrete floating caissons using the floating dock technique. Indeed, the Kugira caisson-building floating dock, the largest in Europe and one of the biggest in the world, holds the world record for the largest constructed block. At 56 metres high, 74 metres long and 49 metres wide, it can produce concrete caissons weighing up to 24,000 tons. ACCIONA used it to construct the shipyard dock in the Port of Açu in Brazil, the largest in Latin America, which has 3.8 km of docks, of which 2.8 km were produced with caissons manufactured on-site by the Kugira.
