Abstract

This research proposes an improved mathematical model which can be used to calculate wheel over point (WOP) for a ship's route optimisation. WOP is a marking made on the charted course to demonstrate where the ship must initiate the course alteration to guarantee that it follows the route. The advance transfer technique (ATT) was used to determine WOP. Through practical exercise, two gaps were identified in ATT. From there, an improved mathematical model, namely ATMM, were developed. A preliminary manoeuvring analysis was then carried out in this study using a ship simulator for ATMM and the existing ATT. Then, the cross-track distance produced by both methods were compared to verify the difference. It was found that the ATMM produced better result in maintaining a ship on its course. This research's mathematical model is expected to be used onboard ship and used in the Electronic Chart Display and Information System to aid navigator in making more effective course alteration.

车轮过点数学模型

本研究提出了一种改进的数学模型，可用于计算船舶路线优化的轮过点（WOP）。WOP是在绘制的航向上做出的标记，用于表明船舶必须在哪里启动航向变更，以确保其遵循航线。采用先进转移技术（ATT）测定WOP。通过实际操作，发现了ATT中的两个缺口。在此基础上，开发了一个改进的数学模型，即ATMM。然后，在本研究中使用ATMM和现有ATT的船舶模拟器进行了初步的操纵分析。然后，比较了两种方法产生的交叉航迹距离，以验证差异。研究发现，ATMM在保持船舶航向方面取得了更好的效果。该研究的数学模型有望在船上使用，并用于电子海图显示和信息系统，以帮助导航员进行更有效的航向更改。
