Abstract

This study explores the effectiveness of weather-based routing in addressing schedule delays and fuel consumption in maritime operations. Using weather data from the Indonesian Agency for Meteorology, Climatology, and Geophysics, the model calculates resistance factors that influence ship performance. The findings highlight that weather-based routing can mitigate delays caused by adverse weather conditions while improving operational efficiency. Case B as the optimized route according to high wave, despite being longer, mitigates delays by increasing the ship’s speed from 12 to 12.7 knots, allowing it to maintain the Estimated Time of Arrival (ETA). This approach demonstrates that adverse weather conditions do not necessarily lead to schedule disruptions. Additionally, this case also achieves a 1.39% improvement in fuel efficiency by considering wave height as a critical factor. Although the savings are modest due to the relatively short sailing distance, the reduction in fuel consumption has a direct impact on lowering emissions, contributing to greener maritime practices. The results underline the potential of weather-based routing to enhance maritime operations by reducing the negative effects of weather on schedule reliability and fuel consumption.
