The Baltic Exchange would like to increase industry awareness of the positive contribution wind assisted ship propulsion (WASP) could provide in reducing emissions, fuel cost for major shipping routes. The results for each of the standard routes covered by the Baltic Exchange are presented in a traffic light format for the estimated fuel and emissions savings. These are produced by making reference to the standard Baltic ship, speeds and consumptions on the identified Baltic routes.
Outcome traffic light potential for deployment of WASP:
The following table indicates the average savings on the representative Cape routes for those WASP technologies considered. The savings on the other Baltic T/C routes will produce similar fuel savings per day as they are a composite of the representative routes displayed here.
The validated data and simulations in this study are kindly provided by members of the International Wind Ship Association (IWSA). The savings shown here should be treated as an initial guide. Wind route optimisation, not included in these results, will deliver further savings.
Different WASP technologies may generate significantly different savings on specific routes.
WASP technology providers will provide accurate performance predictions based on their technology; contact details are provided in the “Criteria and Inputs” section.
When trading to EU ports, WASP provides the added benefit of reduced compliance costs associated with the EU ETS and FuelEU regulations.

To make the results directly comparable the assessments have been calculated on the basis of round voyages, for a vessel operated on that route for the entire year. Industry standard wind distribution data over a minimum of a 5 year period was used in the simulation. A composite of the major routes simulated can be applied to assess time charter implications.
