Method and Evaluation of a Simplified Propulsion Performance Estimation for Eco-Friendly Navigation Planning Support System

在本研究中，我们提出了一个简化的推进性能估计方法，生态友好的导航规划支持系统，一种天气路由系统。现有的方法需要船体外形文件，但这些文件通常被认为是商业秘密。本文所提出的方法适用于一般特性（至少长度、宽度、深度）已知的船舶。本文提出的方法和程序，包括计算公式，可以很容易地用几种船舶的一般特性值来估算风、波阻力系数。我们用一艘商船来评价这种方法。我们发现相当小的差异，减少燃料消耗的效果和船舶速度估计精度之间的建议和现有的方法。

In this research, we proposed a simplified propulsion performance estimation method for Eco-Friendly Navigation Planning Support System, a type of weather routing systems. The existing method needs hull shape documents, but the documents is generally considered as trade secrets. The proposed method is applicable for ships whose general characteristics (at least Length, Breadth, depth) are known.We proposed the method and a program which contains calculating formulas to estimate wind, wave resistance coefficients easily with several values of ship's general characteristics.We evaluate the method by using a merchant ship. We found quite little difference of fuel consumption reduction effects and vessel speed estimation accuracy between the proposed and the existing method.
