Siwertell, which is part of Kalmar Business Area with Cargotec, has announced that it has secured a contract for an ST 490-M ship unloader from leading Norwegian mineral fertilizer producer, Yara International.

The new unit will join a long serving, existing Siwertell unloader at the company’s Glomfjord site. It will help to ensure continued, efficient, safe and clean unloading of various fertilizers. The order was booked into Cargotec’s 4Q17 order intake, with delivery scheduled for June 2019.

Peter Göransson, Sales Manager & Senior Advisor, Siwertell, said: “Yara was one of Siwertell's first customers, taking advantage of our unique screw-type unloading concept in 1979.

"Its wealth of experience operating a Siwertell unloader, combined with our ongoing support and aftercare were big influences in Yara's decision to once again invest in Siwertell's proven technology.

"Our diverse and lengthy experience with bulk handling systems was also an important factor in winning this contract.”

The new unloader will mainly handle varying types of rock phosphate discharging ships of up to 20 000 dwt, and maintains a continuous rated discharge of 600 tph, with a peak capacity of 700 tph.

Strict environmental regulations meant that, as well high discharge capacities, Yara required an installation designed to meet these requirements too.

Göransson said: “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.

"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.

"These environmental restrictions, combined with the prevailing high winds at the site, limited the number of options for mechanical ship unloaders.

"After evaluating other screw-type ship unloaders, Siwertell's mechanical screw-type ship unloader with its totally-enclosed conveying system was the preferred choice."

The unloader is designed to operate in the Arctic climate, featuring an advanced electrical control system, including the Siwertell monitoring system, known as SIMON. This is a PC-based human machine interface (HMI), which provides quick troubleshooting, easy uploader startup, an analysing tool for problem solving, a preventative maintenance guide and remote access by Siwertell engineers. The unloader delivery also includes a collision protection system against objects on the quay, as well as a CCTV system for safe operation.

Utilising steel structures built in southern Europe and equipment built in Sweden, the unloader will be erected and commissioned at a southern European port, before it is transported to Glomfjord via a heavy lift vessel.
