The Porto Sudeste in Itaguaí: DSI Prepron provides Technical Support for
the Startup of a Conveyor System
The Porto Sudeste do Brasil is a private harbor terminal in Itaguaí located approximately 80km from Rio de Janeiro.
The recently opened harbor has a surface area of approximately 52ha and is currently designed for a capacity of more
than 50 million tons of iron ore and other bulk goods per year. The new harbor premises were mainly built to export iron
ore that is extracted from mines in the federal state of Minas Gerais into other countries.
On the premises, conveyor belts with a length
of more than 4,000m and a carrying capacity
of 12,000t/h were installed that can transport
the iron ore at a velocity of 5m/s. A steel bridge
that leads over a railway track is also part of
the conveyor system.
The bridge is braced by 4 coupled bar tendons
that are protected by ducts. Construction of
the bridge was started by a foreign company,
but never finished. For this reason, the General
Contractor was looking for a domestic
162
company that could carry out the stressing
of the bar tendons and complete the bridge
structure.
Among other local companies, DSI Prepron
was selected to provide a solution and asked
to carry out the tensioning work. DSI Prepron’s
experienced employees retensioned the bar
post-tensioning tendons in accordance with a
precisely defined tensioning protocol, bringing
the steel structure to the right position, thus
ensuring the proper functioning of the bridge.
