The advent of powerful control units and the widespread availability of cheap computers have significantly increased the role of artificial intelligence (AI) in various sectors. In the field of maritime applications, this progress has led to the emergence of Edge AI as an important technology. This research focuses on the application of Edge AI to maritime vessels, addressing key aspects of maritime operations. Using Edge AI, we aim to improve the situation awareness and operational efficiency of marine vessels. This study explores Edge AI integration into marine environments and emphasizes its potential to improve on-board safety, navigation and decision-making processes. Our approach shows how smart units decentralized in large central systems can lead to more efficient and adaptive maritime operations and paving the way for a new era of technologically advanced and environmentally conscious maritime practices.
