![]() ![]() There is a very good agreement in RAO between the experiments and simulations. The response amplitude operator (RAO) is used to compare the measured and simulations dynamic response of the mining vessel. Therefore, this paper uses time-domain coupled numerical model as the research object, considering ocean current, surface wave, pipe dynamics and vessel-pipe contact mechanics, to study the dynamic behavior of the lifting pipe and mining vessel during the process of deep-sea mining using AQWA and OrcaFlex softwares. ![]() The characteristics of coupled motion model have not been fully considered in the existing research. ![]() In deep-sea mining, the coupling dynamic response between the mining vessel and the lifting pipe is a significant problem, which directly affects the structural design of the lifting system and the safety of field operation. ![]()
