FEATURE: EFFICIENCY, DUST CONTROL KEY IN NEW SHIP LOADING/UNLOADING PROJECTS

3,500 hours per year. Across the sites, the Siwertell
systems handle millions of tonnes of grain per year.
Operators include Unitapajós (formerly Bunge
Brazil) and TGPM (formerly ADM de Portos Pará), in
the Port of Barcarena; Cargill Agricola, in Santarém;
and Amaggi (formerly Hermasa Navegação da
Amazônia) in Itacoatiara.
With the exception of Amaggi, all operate Siwertell
ST 790-M ship unloaders with continuous rated grain
handling capacities of up to 1,500 tph. Amaggi has a

"A lightweight unloader was therefore required to
minimize the size of the pontoon and it also had to

protect the cargo operations from the elements," said
Patrik Henryson, sales manager, Bruks Siwertell.
For TGPM, a barge-mounted unloader was needed. It has a small physical footprint and weighs only
254 tonnes. The Amaggi project included a Siwertell
barge unloader and ship loader mounted on a catamaran-type pontoon. The unloader is rail-mounted and
operates along the length of the pontoon, which plays

minal installed at Itacoatiara on the Amazon River.
The unloaders run throughout the whole year, so
a planned maintenance stop once a year is necessary
to ensure continuous operation. The service period
varies but averages two to three weeks and typically involves the replacement of wear parts, mostly
conveyor screws and casings. During this time, a
Siwertell equipment surveyor is always present and
a barge docks with all wear parts and the necessary
machinery to carry out the service work.
"The remoteness of some of these operations
means that these customers often carry a large stock
of critical spare parts as well," said Örjan Westerberg,
service contract engineer, Bruks Siwertell. "This
prudent approach is intended to minimize the risk of
unplanned downtime."
The systems have minimal environmental impact,
which is important since they operate in some of the
world's most scrutinized environments such as the
Amazon River. They are quiet and totally enclosed,
which minimizes any dust creation.
