Transportation costs of forest chips effect significantly
on the competitiveness of forest chip production.
Transportation economy of forest chips is poor due to low
volume weight and low energy density of chips. In
practice forest chips has to be transported from small
storages located on wide area, where the transpor-tation
conditions are often poor. Due to this the transportation
costs increase rapidly as the transportation distance
It is possible to reduce the transportation cost of
forest chips by improving the transportation economy.
This means the improvement of the volume weight of the
load within the limits set by the transportation
legislation, and by increasing the energy density, i.e.
maximisation of the energy content of the load. In summer
it is typical that in the case of relatively dry forest
chips a part of the capacity of a lorry cannot be
utilised due to the low volume weight of the chips and
insufficient filling rate of the load space of the lorry.
One objective of this project is to develop loading
methods for forest chips.
Developing of the transportation logistics can also
reduce transportation costs of forest chips. This means
that the waiting times of the lorries have to be reduced
both at the forest terminals and at the fuel reception of
a power plant. This requires inspection of the total
delivery chain from a forest terminal to the power plant.
Development of the navigation of vehicles between
different storage sites so that extra driving of the
lorries could be eliminated would also increase operating
times of vehicles. Information systems, based on digital
map data and GPS-navigation, have been developed for
control of the transportation. The applicability of these
methods for control of forest chips transportation will
be tested in this project.
