HOPE-Light is software to study the dimensions of cargo ships. It not only provides the ship’s propulsion power but also its maneuverability, sea keeping and cavitation performance related to hull vibration. It specifies main engines suitable for the ship and presents the fuel consumption of each engine. It also gives the rudder form, propeller design, speed in waves and EEDI (Energy Efficiency Design Index) which is applied to vessels for international voyage and having gross tonnage of 400 and above from January 2013. In this paper, two examples of HOPE-Light applications are also presented. One is the relationship between propeller diameter and ship’s fuel consumption at the same speed. The other is the change of EEDI value against the change in deadweight caused by the fullness of ship at the same dimension.
