SeaGuard-AI: An Adversarial Robust Framework For Reliable Sea State Estimation In Autonomous Marine Vessels

Autonomous marine vessels rely heavily on artificial intelligence systems for accurate sea state estimation, which plays a crucial role in navigation, stability control, and operational safety. However, AI-based models are vulnerable to adversarial attacks, where small and carefully crafted perturbations in input data can significantly degrade model performance. Such attacks may compromise safety and reliability, especially in critical maritime environments.This project proposes a novel robustness-enhancing adversarial defence approach to improve the reliability of AI-powered sea state estimation systems. The framework focuses on strengthening deep learning models against adversarial perturbations while maintaining high estimation accuracy. The system integrates adversarial training and defensive mechanisms to enhance model stability under uncertain and hostile conditions. Experimental evaluation demonstrates that the proposed defence strategy significantly improves robustness without sacrificing predictive performance. The results confirm that the enhanced model maintains reliable sea state estimation even in the presence of adversarial disturbances.The proposed approach contributes to improving the safety, security, and reliability of autonomous marine navigation systems.
