Wind-Assisted Ship Propulsion: Full-Speed Results
Estimated daily savings and emissions reductions for fast-speed operations on key Baltic standard routes.
Introduction
This section presents the Outcome Traffic Light potential for deployment of wind-assisted ship propulsion (WASP) at fast speeds. The table below shows the average daily savings on representative Cape routes for the WASP technologies considered.
Other Baltic time-charter routes will produce similar fuel savings per day, as they are composites of the representative routes shown here.
The validated data and simulations in this study have been kindly provided by members of the International Windship Association (IWSA).
These results are intended as initial guidance only. The savings shown here should be treated as initial guidance only.
Wind route optimisation, which is not included here, would deliver further savings.
Different WASP technologies may yield significantly different savings for specific routes. Technology providers can give vessel-specific performance predictions; contact details are available in the WASP Criteria & Inputs section.
When trading to EU ports, WASP provides the added benefit of reduced compliance costs under EU ETS and FuelEU Maritime regulations. Under FuelEU, in particular, significant “wind reward factors” may be obtained. These effectively eliminate the compliance cost of the FuelEU penalty in the near term. This regulation therefore supports a quicker return on investment for vessel trading to the EU/ EEA.

Notes on Methodology
Results are calculated on the basis of round voyages, assuming a vessel is operated on the route for the full year.
Industry-standard wind distribution data covering a minimum 5-year period is used in the simulation.
These Cape routes represent a composite of the major simulations, allowing the findings to be applied to time-charter implications.
