Abstract

Time delay in the remote control of maritime autonomous surface ships (RC-MASS) is a critical factor and a significant area of research. However, current studies are fragmented and lack a cohesive understanding of these delays. This study aims to review and analyze relevant literature on time delays, including policy documents, technical reports, and research papers, to provide valuable insights into RC-MASS operations. Through a systematic search, sources from the past 25 years were examined, and time delay data were extracted and categorized for statistical analysis. The findings indicate an average delay of 56.17 seconds across all categories, with considerable variability. Delays associated with navigation equipment, ship maneuvering, and ship control are prevalent across all vessels, exhibiting large values and wide variability. Although communication delays had a smaller average, they warrant further investigation due to their critical role in RC-MASS operations. This research sheds light on time delay patterns in RC-MASS, helping to identify key areas for improvement and supporting future technological advancements.
