The increasing complexity of naval electrical systems and the demand for higher operational reliability necessitate a shift from traditional maintenance methods to data-driven predictive maintenance solutions. This research examines the effectiveness of IoT-based remote monitoring and diagnostic systems in improving system reliability, cost-efficiency, and operational sustainability in naval engineering. A qualitative-empirical approach was applied, utilizing expert interviews, structured surveys, and field observations to assess the impact of IoT-driven predictive maintenance. The findings indicate a significant reduction in system failures (92/100), maintenance costs (89/100), and operational downtime, demonstrating the effectiveness of real-time fault detection and automated diagnostics. Additionally, the study identifies challenges in infrastructure readiness (78/100) and cybersecurity concerns (82/100), which must be addressed for large-scale implementation. While the adoption rate (88/100) reflects strong industry support, skill readiness gaps (80/100) suggest a need for enhanced technical training in maritime education. The research concludes that IoT-based predictive maintenance offers a transformative approach to naval maintenance strategies, ensuring sustainability, efficiency, and enhanced fleet readiness in modern maritime operations.

This research explores the impact of fiscal policies on maritime economics, focusing on macroeconomic stability, sector-specific resilience, and sustainability initiatives within maritime industries. Through qualitative analysis and expert perspectives, the study examines how fiscal interventions influence economic growth, address regional disparities, and promote environmental stewardship in maritime sectors. Key findings highlight the effectiveness of fiscal tools in stabilizing economic fluctuations, fostering innovation, and enhancing industry competitiveness. Challenges such as regulatory complexities, uneven distribution of fiscal benefits, and the need for enhanced fiscal transparency are also discussed. The research underscores the importance of tailored fiscal strategies that support inclusive growth, sustainable development, and global competitiveness in maritime economies.
