Abstract

Abstract A weather routing tool is presented based on forecasted weather data along the route and considering safety aspects. The tool aims to determine the optimal path for the minimisation of the fuel oil consumption, ensuring a safe passage. It is developed in MATLAB and considers detailed ship characteristics. Specifically, ship's motions and fuel oil consumption of the main engine during a potential path are estimated. For the latter, a physics-based model for a specific vessel is developed where tools of different level of detail are utilised to calculate the various resistance components. A speed management strategy along the route is specified as well as safety criteria representing acceptable limits of ship's responses. When the set criteria and constraints have been set, a genetic algorithm is used to find the optimal route by means of ship's heading or by considering both heading and ship's power settings as variables to minimise the fuel oil consumption. The search space of the algorithm lies within a predefined envelop, but still the evolutionary optimisation approach used has no pre-assigned values to any possible candidate waypoint.

基于预测天气数据并考虑安全标准的船舶路径优化

摘要:提出了一种基于沿线天气预报数据并考虑安全因素的天气路由工具。该工具旨在确定燃油消耗最小化的最佳路径，确保安全通过。它是在MATLAB中开发的，并考虑了船舶的详细特性。具体地说，估计了船舶在潜在路径中的运动和主机的燃油消耗。对于后者，开发了特定容器的基于物理的模型，其中使用不同细节级别的工具来计算各种阻力分量。指定了沿路线的速度管理策略以及代表船舶反应可接受限度的安全标准。在给定条件和约束条件下，采用遗传算法以船舶航向为变量，或同时考虑航向和船舶动力设置为变量，寻找最优路线，使燃油消耗最小。该算法的搜索空间位于预定义的包络范围内，但使用的进化优化方法仍然没有为任何可能的候选路点预先分配值。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
