Mobile Siwertell unloaders meet multiple port needs

Over the past four months Cargotec has secured orders for three new mobile Siwertell ship- unloaders for ports in Turkey, Denmark and Sweden, confirming its position as an advanced bulk-handling technology provider.
“Cargotec has delivered more than 300 Siwertell units worldwide, 100 of which are mobile systems,” says Jo¨rgen Ojeda, Cargotec sales director. “Clients recognize our experience and the well-respected Siwertell mobile unloader technology.”
He adds:“The Siwertell road-mobile unloader is a perfect choice for clean, dust-free, handling of dry bulk material. Its unique design makes the Siwertell unloader one of the most environmentally friendly shore-based ship unloading systems available. Dust- free handling, and low energy consumption, along with minimal exhaust and sound emissions also mean that it has the advantage of being able to be used in sensitive sites or those close to populated areas.”
The first of these new orders has now been commissioned and sees a diesel-powered, trailer-based Siwertell 10 000 S unit with a dual bellows system and dust filters in operation for Muhammet Gu¨mu¨stas, in Trabzon, Turkey. The new unit handles cement at a rated capacity of 300tph (tonnes per hour).
“The mobile Siwertell unloader was originally designed for handling cement, so it is naturally perfect for the job. With its enclosed conveying line, this system is also environmentally friendly as it ensures dust-free and high-capacity unloading operations,” explains Ojeda.
A similar unit is due to be commissioned for Aalborg Portland in Aalborg, Denmark. It will handle fly ash at a rated capacity of 250tph.
“For this installation, a mechanical solution was preferred by the client as it had to be smoothly integrated into an existing mechanical receiving system at the jetty.”
He adds:“Low maintenance and operational costs of the mobile Siwertell unloader, combined with a high unloading capacity, will also ensure cost-efficient operations for Aalborg Portland for a long time to come.”
The third order is for an electrically-powered, gantry-based, ATEX-classified Siwertell 15 000 S unit. It will be commissioned by the end of next year for Fortum Va¨rme, which is co-owned by the City of Stockholm, Sweden.
The unloader will be installed in Stockholm and has a rated capacity of 330tph. It will handle biomass including olive kernels, wood pellets, and wood briquettes. It will also be equipped with tube sleeves and noise hoods to minimize noise pollution. “For this contract, our focus is to deliver an unloader with the required capacity, minimal dust emissions and low noise generation.”
Fortum Va¨rme is the Swedish part of Fortum Heat Scandinavia, which produces district heating, district cooling and electricity in combined heat and power plants. Fortum Va¨rme is building a new fuel handling facility, Energihamnen, in Gothenburg, so that it will be able to increase the amount of biofuels in Va¨rtaverket, Stockholm. “An important part of the company's plan is to invest up to 15 billion SEK in new combined heat and
power plants, as its goal is to provide resource and climate neutral district heating by 2030; our Siwertell units will be an integral part of this,” Ojeda says.
