“…fuel types used), especially during route planning (International Maritime Organization 1999). Seafarers report perceiving the conflicting goals (financial, safety and efficiency) as hindrances to energy-efficient operations and impacting their feeling of autonomy (Zoubir et al 2023a). In that study, these challenges were reported to further exacerbated by high workload and fatigue resulting from task complexity, understaffing, and long working hours.…”

Onboard Decision Support Systems (DSS) for energy-efficient maritime route planning can be critical in achieving global goals for carbon reduction and sus-tainable transportation. However, research has shown that seafarers’ fuel reduc-tion behaviors are hindered by goal conflicts and workload, reducing motivation and efficient use of automated supporting systems. Therefore, we examined sea-farers’ (N = 22) interactions with a DSS while planning routes in a high-fidelity bridge simulator. To gain a comprehensive picture, we assessed Usability, User Experience, Workload, Basic Psychological Need (BPN) fulfillment and Prefer-ences for Automation Types, and conducted interviews. Despite positive system evaluation, especially hedonic User Experience, our analysis of BPN data points towards a perception of reduced autonomy when using the DSS. Similarly, sea-farers frequently requested features increasing their autonomy (e.g. route editing). Our findings highlight the significance of considering BPNs, especially autono-my, in the human-centered design of DSS and automated tools for maritime transportation. Prioritizing these aspects can contribute to broader environmental and efficiency goals.
