By test-running the self-driving truck, Stora Enso has collected information on what kind of environmental and safety benefits and cost savings can be achieved with the state-of-the-art vehicle when driving around the mill grounds.
“The use of the automated truck has considerably increased safety in the mill area, particularly in the vicinity of wood chip piles and warehouses. The use of automation has also reduced emissions. Testing has gone well, and the truck does the right things in the right places. The test was planned to last for one year, but we have decided to continue it in order to gain a more comprehensive experience of how the truck works in the different seasons,” says Lauri Kuusisto, Director of Operations at Stora Enso Wood Supply Finland.
For example, the driver will in the future work in the remote-control room, and thus benefit from better ergonomics. The automated truck is expected to reduce emissions by optimising engine operation and route selection. Reduced fuel consumption will also bring financial savings.
The maximum speed of the automated vehicle moving in the grounds of Stora Enso’s Uimaharju mill between the sawmill and the pulp mill is 20 km per hour. The truck transports wood chips from the sawmill to the pulp mill, travelling the 1.4 km distance about 15 times a day. The wood chips, which are a by-product of sawmilling, are used as raw material for pulp production.
Safety is the number one issue in the testing of the vehicle. During the initial stage of the testing process, a driver has been in the truck’s cabin monitoring the progress of the test. Later this year, the operation of the truck will be controlled remotely from outside the vehicle.
A number of things are considered in the truck’s safety technology and that allow it to be called a truck with six senses. These senses are:
Testing of the automated vehicle is a joint project between Stora Enso and wood chip transport operator Mantsinen Group. The smart control system and equipment for the vehicle are supplied by Hiab (part of Cargotec), which has been developing the system together with VTT. The safety work also involves InnoTrafik and VTT. Nokian Tyres is also participating in the project, testing Nokian Tyres IntuituTM smart tyres.
Stora Enso’s Uimaharju sawmill produces sawn pine timber. Located in the same mill area, Stora Enso’s Enocell pulp mill produces dissolving pulp and softwood pulp for the needs of, for example, the textile and paper industries. A total of approximately 300 people work in the mill grounds.
