Introduction
Marine navigation is the lifeblood of international trade and the global economy, facilitating over 80% of worldwide commerce [1].The maritime industry's pivotal role in sustaining global trade cannot be overstated.In a rapidly evolving technological landscape, intelligent and safe marine navigation has emerged as a critical domain within the maritime sector [2].The integration of cutting-edge technologies, including artificial intelligence (AI), machine learning (ML), and big data analytics, holds the promise of significantly enhancing the intelligence and safety of ships navigating our oceans [3].These advances are not only transforming the ways in which ships traverse vast sea expanses but also revolutionizing maritime logistics, fleet management, and environmental monitoring [4,5].
With the advent of AI and ML, predictive algorithms are now being employed to optimize routes, thereby reducing fuel consumption and minimizing the environmental impact [6].Big data analytics enables the processing of massive amounts of data from various sources, such as satellite imagery, oceanographic data, and automatic identification system (AIS) data, providing insights that were previously unattainable.This convergence of technology and marine expertise is paving the way for autonomous ships, which promise to further revolutionize the industry by enhancing efficiency, safety, and reliability [7,8].Furthermore, the integration of IoT (Internet of Things) devices in maritime operations is facilitating the real-time monitoring and maintenance of critical ship components, thus preventing failures and ensuring smoother operations at sea [5].Cybersecurity, too, has become a paramount concern, with these technological integrations necessitating robust security protocols to safeguard navigational and operational data from cyber threats [9].
As we enter this new era of safe, intelligent, and sustainable navigation, it is evident that the maritime industry is on the brink of a technological revolution [10].The potential benefits extend far beyond the shipping companies themselves, impacting global trade and environmental conservation and even reshaping international regulatory frameworks [11].In essence, the fusion of technology with traditional maritime practices is not just a trend but also a transformative movement, setting the course for a more efficient, safe, and sustainable future in marine navigation.
