由於能源價格攀升與溫室效應問題日漸嚴重，船舶航行過程如何節能減碳成為重要的問題，目前很多造船廠與航運公司都以氣候航程的概念來開發船舶導航輔助系統，希望能減少二氧化碳排放提升能源使用效率，同時兼顧船組人員、船舶與貨物之安全性。本文即以相同之概念來發展一套適用上述功能之氣候航程系統，希望能對造船及航運界之節能減碳問題有所幫助。
本研究以2D截片理論為基礎計算不同航行姿態下船體運動之反應振幅運算因子(RAO)與在波浪中航行之附加阻力，並結合ISSC能量波譜計算船體運動有義值與平均附加阻力；配合海氣象資料，可計算出波浪、風與洋流對船舶航行之影響，建立在實際海況下之航行資訊模擬系統。
本文將不同航行姿態下船體運動及附加阻力模擬結果與實驗結果進行比較，來驗證理論計算結果的正確性，並提供航行姿態較佳之選擇；另外在氣候航程系統中加入實際海況下船舶航行受洋流之影響，使航線規劃更貼近船舶實際航行情況，並開發以洋流為考量的航線規劃方法，以安全航線、低附加阻力航線及洋流考量航線等不同航線規劃方法進行規劃比較，探討是否可以洋流特性來做為選擇航線之依據，輔助船舶以安全且較省油的方式航行至目的地。

The rising fuel price and the greenhouse effect on the environment gradually become serious problems. How to save energy and reducing carbon dioxide emissions during the ship voyage has become an important issue. At present, many shipbuilding and shipping companies base on the concept of weather routing to develop navigation support systems to reduce carbon dioxide emissions and improve energy efficiency and safety of the ship. This study develops several algorithms of ship touting with the same concept to help shipbuilding and shipping companies.
In the study, the ship motion response amplitude operators and added resistance are calculated by the existing computer program including the well-established strip theory. The significant values for the motion and added resistance are obtained by ISSC’s spectrum. The simulations include the effect of waves, wind and ocean currents on the ship with real-time weather information in every waypoint. Then the sailing information simulation system under real sea conditions can be established.
The theoretical calculations of ship motion and added resistance with respect to different trim are verified by experimental results which can provide a better alternative navigational gesture for the ship. The optimal choice for the current effect on the navigation route is also included in the present study which can offer the new route planning model with the current effect to reduce fuel consumption. Consequently the new model developed here can support vessels to have the safe navigation and more energy-saving way to the destination.
