PRESS RELEASE: The specially-designed system will serve the company's new terminal located in Dublin Port's Alexandra Basin in Dublin, Ireland, ensuring close to zero dust emissions for the operator. The order was booked into Bruks Siwertell Group's June quarter order intake.

Peter Göransson, sales manager and senior advisor at Siwertell, said: "Boliden required a flexible system capable of handling a variety of cargoes and a wide range of vessel sizes, but with a very strict approach to dust emissions. Our lengthy experience and expertise in bulk material loading was a significant factor in winning this contract, including the fact that no efforts were spared in designing a triple-enclosed loading system that will ensure as close to zero emissions as technologically possible for the operator.

"A high loading capacity, combined with easy system operation and low service and maintenance costs, were also significant factors in Boliden's decision to invest in Siwertell's market-leading technology. Additionally, it complies with best available technology (BAT) and reference document (BREF) regulations."

The new system comprises a triple-enclosed belt-type shiploader, with luffing and slewing capabilities, a reversible shuttle-belt conveyor with dual remotely-operated connection points, as well as a triple-enclosed jetty and overland conveyor.

It will handle zinc and lead concentrates, which are transferred from rail wagons to a receiving storage building. From here, a conveyor belt leads to a new quayside facility in Alexandra Basin. Siwertell designs are well-suited for sticky and hard-to-handle materials and the new system will be capable of loading ships of up to 10,000dwt at a continuous rated capacity of 600t/h.

Göransson explained: "Based on Siwertell designs, and with production and construction supervision as a part of the delivery scope, Siwertell, together with local partners, will have full control of the project from design to handover. With carefully-selected components from Swedish and other European sub-contractors, we will deliver an efficient, reliable, high-performance system with low operational and maintenance costs."

The steel structures for the shiploader will be produced in Far East and equipment will be mainly supplied from Sweden. The overland and jetty conveyor will be produced locally in Ireland with the conveyor equipment supplied from Europe. The system will be erected and commissioned at Dublin Port in partnership with an expert Irish company and is expected to be fully operational by August 2019.
