Kemi
The safest and most efficient logistics chain in the field
The increasing production volumes in Kemi call for efficient, reliable, and seamless logistics. The bioproduct mill’s transports are efficient, safe, and environmentally friendly from the forest to the customer. New technology and automation are used for unloading wood, as well as for transporting pulp bales.
Once Kemi bioproduct mill comes online, it will receive daily calls from nine wood-carrying trains and around 250 articulated lorries, 180 of which will be transporting wood. “We want to keep transport and storage times as short as possible in the procurement and supply chains. The goal is to direct the bulk of in- coming logs straight to production. The pulp bales produced will then be carried by conveyors to extra-long HCT (High Capacity Transport) trucks, which run to the Port of Kemi on a 24/7 basis”, says Pasi Pulkkinen , VP, Land Logistics at Metsä Group. Separate routes for trains and motor vehicles Larger transport and raw material volumes require new solutions, espe- cially for road and rail arrangements in the mill area. The Finnish Trans- port Infrastructure Agency will lengthen and electrify two rail tracks in the Kemi depot and a new section of track will be built at the north side of the railway yard. It will be connected to the electrified private track built by Metsä Fibre, allowing the use of electric locomotives to haul wood. Transport safety will improve when trains no longer intersect with other traffic. “Around two thirds of the wood flow arrives at the mill by train, and the rest is transported by road. Heavy traffic, the mill’s passenger traffic and train traffic will be safely assigned to separate routes.” The increasing volumes have spurred a search for new solutions and technology. The woodyard is equipped with electrically powered auton- omous mobile overhead cranes; lorries and trains carrying wood drive straight under them. In practice, the cranes handle unloading inde- pendently.
“We have worked with VR, the state railway company, to create an effi- cient transport concept for incoming wood. A full train of wagons can be unloaded in two hours. One lorry takes nine to twelve minutes to unload.” Pulp bales move smoothly to the port The logistics of outgoing goods have also been redesigned. Pulp deliver- ies from the mill to the Port of Ajos, 15 kilometres away, are handled by Kuljetusliike Kalevi Huhtala Oy, a road transport company. There are nor- mally three biodiesel HCT trucks operating round the clock. “We can transport 72 tonnes of pulp in a single delivery, which is around 1.5 times the load carried by a conventional lorry. This decreases the car- bon footprint of these transports by 30 per cent,” says Pulkkinen. At the Port of Ajos, the pulp bales end up in a product warehouse covering 37,000 square metres, which was specifically constructed for the new bioproduct mill and offers fully fossil free, environmentally friendly oper ations. All the warehouse’s forklift operations and its loading fleet are electrified. In the port, the bales are moved to a conveyor, and forklifts transfer them to the warehouse, where an electric crane loads them onto ships. Ideally, there is no need for traditional interim storage, as goods move almost continuously. Pulkkinen describes it as both challenging and rewarding to design and construct such a smooth logistics chain. “We have worked hard to design and implement everything down to the very last detail, in close cooperation with the City of Kemi, the Port of Kemi, the Finnish Transport Infrastructure Agency and our logistics part- ners. An efficient logistics chain helps us ensure reliable deliveries to our customers around the world.” •
