In November, Cargotec secured a breakthrough contract for two large Siwertell coal unloaders from Formosa Petrochemical Corporation (FPC), part of the Formosa Plastics Group. The unloaders will be the largest that Cargotec has delivered so far and may start a trend that sees more steel plants using Siwertell machines for dedicated coal unloading.
The equipment will be delivered to Formosa Plastics Group’s newly-built Ha Tinh steel plant in Vietnam’s Son Duong Port during the last quarter of 2014. Each ST 940-DOB unloader will be feeding coal with a rated capacity of 2,400t/h.
"Siwertell systems can deliver huge cost savings – in the region of $2.5 to $3 million per year for this particular operator – in comparison to traditional systems, because ships will spend much less time at the unloading berth," says Per Karlsson, President for Bulk Handling Business Line. "Until now the industry has been reluctant to invest in separate intake systems for coal and iron ore, however, savings on this scale cannot be ignored and we are confident that this order will start a trend that sees more steel plants using Siwertell machines for dedicated coal unloading.
"In a competitive international bidding process, we offered the customer the most efficient unloading system with a high through-ship capacity, which will deliver huge cost savings and also provide a clean, dust-free operating environment; all at a competitive price," notes Mr Karlsson.
The steel plant is owned by Formosa Plastics Group’s daughter company Formosa Ha Tinh Steel Corporation; its annual intake of coal is estimated to be about 7.8 million tonnes. The unloaders are expected to be operational by mid-2015 and will be erected on site with their main system components coming from Europe, and steel structures from Vietnam.
