SimWAPS is a tool for estimating the first-approach savings potential of wind propulsion for commercial vessels. 

Discover the tool here.

To create this tool, CRAIN drew on its solid experience of wind propulsion and various aerodynamic systems.

To keep this online tool accessible, several assumptions have been made and average coefficients used. However, the user must bear in mind that the actual performance of a wind system depends on many aspects, such as its manufacturing quality, structural behavior, interaction with the environment, dynamic effects, control, etc. 

Thus, even when based on the same concept, the actual performance of a vehicle system can vary from one supplier to another. That's why the tool offers a range of performances for each type of propulsion system. These ranges may not accurately reflect the actual performance of a specific system. 

An effort has been made to obtain realistic and conservative results.

For a given project, a specific study must be carried out to take proper account of the various effects that may occur. Please do not hesitate to contact us, whether you are a shipowner, ship operator, naval architect, solution provider,...
