Basics
👋🏻 Welcome
Welcome to the SimWAPS online documentation! SimWAPS is an online tool for the initial assessment of the potential of wind-assisted-wind-propulsion for commercial ships. Here you'll find : A presentation of the tool and how to use it., A detailed des...
Quickstart
As soon as you log on to SimWAPS, you'll be taken to the home view. This view is organized to provide a maximum of informations. Calculation cases are launched from the User Input Section on the left of the screen. The calculation sequence is as follow...
For Further Informations
SimWAPS results are based on numerous assumptions and simplifications. To refine the results, CRAIN has a range of experimental and numerical tools at its disposal. If you wish to refine your project, If you'd like to find out more or refine your projet, ple...
Glossary
Lift and Drag coefficients : Aerodynamic forces can be expressed as a coefficient that depends neither on the size of the system, nor the apparent wind speed seen by the system. These coefficients, which depend mainly on the type of velic propulsion used, ar...
Types of WAPS
The renewed use of wind power for commercial ship propulsion requires systems to be adapted to the operational constraints of commercial vessels. Similary, aerodynamic performance can be reviewed in the light of advances in fluid dynamics, advanced computing c...
Routes & Weather
In SimWAPS, the choice of the route directly influence the ship performance under sails. SimWAPS offers a sample of sea routes for which wind statistics have been calculated from historical meteorological data (ECMWF - ERA5). SimWAPS does not support weather...
Types of Ships
In SimWAPS, a ship is modeled according to three input parameters. Type : Determines overall proportions and structural characteristics, Length : Directly influences dimensions and hydrodynamics performance, Operational Speed : Used to compute apparent...
Performance Model
SimWAPS has been created to limit the number of parameters required by the user, and focuses on the effects that have the greatest influence on the potential for wind propulsion. Deck-mounted systems are defined by 2 aerodynamic parameters and 2 geometric pa...
