Abstract
Reliable ship performance analysis can help prevent misguided navigation decisions and enable a more accurate estimation of fuel consumption. Supporting decarbonisation goals and following increasingly stringent maritime regulations will depend on these capabilities. While analysis tools and data collection have come a long way, the processing and managing of ship performance data is still continuously challenged by its complexity and inherent imperfections. Despite its importance, there is still little systematic research on how to process data confined to this field. This paper presents a comprehensive review of methodologies aimed at addressing data-related challenges in ship performance analysis. Based on literature published between 2014 and 2024, the authors identified major data sources such as AIS, onboard sensors, and noon reports, and we examined common quality issues. Subsequently, key processing techniques, including data synchronisation, missing value imputation, data cleaning, and uncertainty management, are evaluated in terms of their applications, effectiveness, and limitations. This review also highlights a significant gap due to the lack of a consistent unified processing pipeline. Resolving these challenges requires not only improved methodologies but also collective efforts to establish benchmark datasets and best practices. These research efforts are critical to enabling reliable data-driven decisions and sustainable ship operations.
