To provide a ship performance analysis system capable of making a highly accurate or optimal ship allocation plan.SOLUTION: The ship performance analysis system comprises a ship speed detector to detect a ship speed, a fuel consumption detector to detect fuel consumption of at least one of the main engines for propulsion, a display unit to display the plotted graph of the measuring points determined by the ship speed detected by the ship speed detector and by the fuel consumption detected by the fuel consumption detector, and an arithmetic unit to predict the future change of the performance deterioration rate based on the history of the performance deterioration rate while calculating the performance deterioration rate using the ship speed detected by the ship speed detector, the fuel consumption detected by the fuel consumption detector and the reference performance curve drawn by the relationship between the initial ship speed and fuel consumption.SELECTED DRAWING: Figure 1 【課題】精度の高いまたは最適な配船計画を立てることができる船舶性能解析システムを提供する。【解決手段】船舶性能解析システムは、船舶の速度である船速を検出する船速検出器と、少なくとも１つの推進用の主機の燃料消費量を検出する燃料消費量検出器と、初期の船速と燃料消費量との関係を定めた基準性能曲線が描かれたグラフであって、船速検出器で検出された船速および燃料消費量検出器で検出された燃料消費量で定まる計測点がプロットされたグラフを表示する表示装置と、船速検出器で検出された船速、燃料消費量検出器で検出された燃料消費量、および基準性能曲線を用いて、性能悪化率を算出するとともに、性能悪化率の履歴から、性能悪化率の将来的な変化を予測する演算装置と、を備える。【選択図】図１
