Abstract
We present a method for ice-aware maritime route
optimization. Our aim is to increase the safety and
efficiency of maritime transport under icy conditions.
The proposed method is based on the A algorithm,
developed by Hart et al. It uses a model of maritime
navigation, consisting of (1) a sea spatial model, (2)
ship maneuverability model, (3) sea ice model, and (4)
ship performance model. The sea ice model, which provides
a snapshot of the sea ice conditions, is based on
previous work by the Finnish Meteorological Institute.
The ship performance model, based on previous work by
Kotovirta et al., estimates ship transit speed as a
function of ice conditions and ship design parameters.
The main novelties in this paper are the application of
the A algorithm to maritime route optimization and
development of an associated cost function that takes
into account ice conditions and available icebreaker
assistance. We present preliminary results based on the
method, using the Baltic Sea as a case study. Generated
routes are compared with historical routes under the same
ice conditions. Areas of future work and needed
enhancements are briefly discussed
