Abstract: This paper reviews the research status of intelligent ship berthing technology at home and abroad in recent years. The hotspots and applications of berthing technology are summarized respectively from three aspects of berthing mode, mathematical model, and control algorithm. The remaining problems of this domain in aspects of autonomy, modeling accuracy, path planning, control algorithm, energy-saving effect, and system test are analyzed. Based on the actual needs of navigation, it is proposed that the next step needs to make breakthroughs the core theories and key technical problems such as information fusion, online modeling, intelligent decision making, optimization algorithm, green energy saving, and test technology. Improve the autonomy, robustness, rapidity and "toughness" of berthing technology, so as to help realize safe, green, and efficient intelligent shipping.
