2 Definitions

  2.1 For the purpose of these guidelines, the following definitions should apply:

  • .1 Available effective power is the multiplication of effective power Peff and availability factor feff as defined in the EEDI calculation.

  • .2 Wind propulsion systems belong to innovative mechanical energy efficient technologies which reduce the CO2 emissions of ships. These proposed guidelines apply to wind propulsion technologies that directly transfer mechanical propulsion forces to the ship's structure (sails, wings, kites, etc.).

  • .3 Global wind probability matrix contains data of the global wind power on the main global shipping routes based on a statistical survey of worldwide wind data. A detailed determination of the global wind probability matrix can be found in a separate submission (INF paper).
