The employment of Unmanned Aerial Vehicles (UAVs) has demonstrated considerable promise for enhancing surveillance, safety, and communication in the context of maritime operations. However, the integration of these systems requires a comprehensive understanding of the associated hazards. This paper examines the risks associated with UAVs, categorizing them into the following domains: operational hazards (e.g., mid-air collisions and battery limitations), environmental challenges (e.g., weather and wildlife interactions), technical failures (e.g., software and hardware issues), security threats (e.g., misuse and cyberattacks), and regulatory compliance. The principal findings underscore the necessity for the implementation of robust risk management strategies that are specifically tailored to the context of maritime UAVs operations. In order to ensure the safe integration of UAVs in maritime environment, it is essential to implement collision avoidance systems, enhance UAV design for maritime conditions, establish rigorous testing procedures, strengthen cybersecurity, and create standardized regulations. Adherence to these measures will facilitate the enhancement of the efficiency and security of UAV operations within the maritime industry.
