應用能效指標及統計方法進行船舶能效分析之研究

This research collected real-time navigation data from a bulk carrier by using big data equipment systems on board. The data was sent to the onshore team for energy efficiency analysis. The data collected were speed, fuel consumption, average draft and rudder angle etc. This research proposes a method for investigating energy efficiency performance. Then, further defining the energy efficiency indicator, its baseline parameters and relative data revisions. In conclusion, using the above method to monitor ships’ condition, besides other than using the traditional method of evaluating the energy efficiency of a ship, a statistical method was also used (the hull degradation monitor model). Both results of the respective methods have the same conclusion, therefore signifies that the ship is in good condition. Finally, according to V_d or P_d, we found that the unstable conditions during the navigation are mostly influenced by environment.
