The present invention relates to an optimum sea route prediction supporting system and a method thereof. The method comprises the steps of: receiving a vessel data material and additionally calculating a submerged surface area by using a simple equation; receiving the vessel data material and a marine weather material to calculate resistance under a calm water condition, wind resistance, steering resistance, drift resistance, shallow water resistance, and resistance of hull surface roughness and additionally, calculating added resistance due to waves by using another simple equation; estimating propulsion performance of a vessel by aggregating the resistance calculation results and calculating a propulsion coefficient; calculating a regression equation of a marine vessel accident risk index by time period and by vessel accident type through a binary logistic regression model by using a vessel sailing material and a marine weather material that have been made in the past; and estimating a marine vessel accident risk index by time period and by vessel accident type through the regression equation of a marine vessel accident risk index, which is calculated by using a vessel sailing material and a marine weather material at a specific time including past, present, or future. Accordingly, the optimum sea route prediction supporting system and the method thereof can efficiently calculate and estimate the propulsion performance of a vessel.
