The Weather Routing Tool (WRT) is an open-source Python library developed by 52°North for calculating optimal maritime routes. Its development began under the MariData project (funded by BMWE) and is currently continuing as part of the EU TwinShip project. WRT’s primary objective is to minimize fuel consumption in the shipping industry by using environmental data to help route vessels. This data includes various meteorological parameters, such as wind and wave conditions, as well as water depth information.
