Cargotec's 300th Siwertell unloader contract from PT Petrokimia Gresik
Cargotec's 300th Siwertell unloader contract will see the company deliver its safe, efficient and environmentally-friendly Siwertell system to the Indonesian fertiliser producer, PT Petrokimia Gresik
In January this year,
Cargotec secured a second contract for a Siwertell ship unloader
with the Indonesian fertiliser producer, PT Petrokimia Gresik. "The
customer chose our Siwertell technology again, because they wanted
a highly efficient continuous screw-type unloader, which was also
capable of safely handling potentially explosive materials, such as
sulphur," says Anders Paulsson, Cargotec Sales Manager, Bulk
Handling. "We have by far the most knowledge and experience of
screw-type unloaders, and can offer them at competitive
prices."
Cargotec supplied Petrokimia Gresik
with a ST640-DOB Siwertell ship unloader in 1996, and this latest
contract will see it deliver the latest version of the same type
within the next 13 months. The ship unloader will be erected at its
operating site in Gresik, Indonesia and able to handle rock
phosphate, sulphur, urea and ammonium sulphate at a rated capacity
of 1,000t/h. Petrokimia plans to have the site running from mid
2013.
"With a totally enclosed system, our
Siwertell unloaders offer customers an environmentally-friendly
solution. Also, for handling sulphur, the unloader has a built-in
safety mechanism; our award-winning 4S system," highlights Mr
Paulsson.
The 4S (Siwertell sulphur safety
system) is designed to minimise the risk of explosions and detect
fires. Cargotec now applies the 4S to all ship unloaders aimed for
sulphur unloading, both those for larger ships and road-mobile
unloaders for smaller ships.
To prevent explosions and fires, the
Siwertell unit is equipped with nozzles that spray water at the
inlet feeder and in the conveyor transfer points. An automatic
lubrication system is installed to lubricate and cool down end
bearings and intermediate bearings. There are also fire detectors
along the conveying line, and when activated these automatically
start the fire extinguishing system spraying water and stop the
conveyors. This is vital to prevent fires entering the storage
building. To manage any explosion, the conveyor's steel casings are
reinforced with extra-thick steel, and explosion-venting valves are
fitted along the conveyors and dust collectors to relieve
pressure.
