Siwertell has won a contract for an ST 490-M ship-unloader from Norwegian mineral fertiliser producer Yara International.
Siwertell, part of Cargotec’s Kalmar business, said the new unit will join a long-serving, existing Siwertell unloader at the Yara’s Glomfjord site, ensuring the continued efficient, safe and clean unloading of various fertilisers. The order was booked into Cargotec’s Q4 2017 order intake, with delivery planned for June 2019.
The new unloader will predominantly handle various types of rock phosphate, discharging ships of up to 20,000 dwt, and maintaining a continuous rated discharge of 600 tph, with a peak capacity of 700 tph.
Norway’s stringent environmental regulations meant that, in addition to high discharge capacities, Yara needed an installation designed to meet these requirements as well.
“Siwertell’s screw-type ship-unloader was chosen for its environmental credentials, which include high levels of efficiency and a totally enclosed conveyor system, eliminating dust emissions and spillage,” explained Peter Göransson, sales manager and senior advisor, Siwertell.
“This technology is the only safe and acceptable discharge method that can be used in sensitive marine environments, such as a Norwegian fjord, where very strict environmental regulations are in force and air and water pollution is totally out of the question.
Designed to work in the harsh Arctic climate, the unloader is also equipped with an advanced electrical control system, including the Siwertell monitoring system, known as SIMON, a PC-based human machine interface (HMI), which offers quick troubleshooting, easy unloader start-up, an analysing tool for problem-solving, a preventive maintenance guide, and remote access by Siwertell engineers.
A collision protection system against objects on the quay, and a CCTV system for safe operation, are also included in the unloader delivery.
Using steel structures produced in southern Europe, and equipment built in Sweden, the unloader will be erected and commissioned at a southern European port, before being transported by heavy lift vessel to Glomfjord.
