Survey on hydrodynamic analysis of ship–ship interaction during the past decade

With the increasing size of ships, the impact of ship–ship interaction on navigational safety has received significant attention. Therefore, the investigation of ship–ship hydrodynamic interaction is a crucial research field in ocean engineering. First, we review the hydrodynamic response of ship–ship interaction in the past decade. The systematic classification of different operating conditions, including lightering operations, overtaking maneuvers, and encountering ships, is carried out according to the investigation subjects and research methods. Second, this paper overviews the application of numerical methods, discusses the analysis of the effects of different influencing factors (shape, draft, flow velocity, and incident waves), and provides data sources for topics of interest. Finally, despite the pioneering work of predecessors, there are still challenges to overcome. According to the actual sea conditions, flow field variations, and algorithm applications, the discussion section analyzes the influence of external conditions, the effect of internal sloshing on ships, and the advantages and disadvantages of some algorithms. This paper provides references for investigating flow fields and methodologies of ship–ship interaction. Additionally, it suggests that the direction for future work addresses the shortcomings of current research.
