In the existing ocean engineering structure, the application of a jacket platform and a large-scale offshore floating wind turbine can be the most extensive, but at the same time, the accident rate of the two types of platforms is higher in all ocean platforms. According to incomplete statistics, in the event that the jacket platform and the floating fan are knocked to generate overturning every year, the accident caused by ship knocking accounts for more than 20%, and the loss of manpower, material resources and financial resources caused by the accident is very huge. Even under the condition that the current ocean engineering field has been developed for a long time, people pay more attention to the safety problem of the ocean engineering structure.
At present, scholars at home and abroad carry out a great deal of research on the failure mechanism of the ocean engineering structure, but most scholars at home and abroad are based on numerical simulation and theoretical analysis, little and few experimental research on the collision problem of the ocean engineering structure is carried out, and a secondary collision phenomenon possibly exists on the same jacket, namely the secondary collision phenomenon is not found or discovered in time after the primary collision phenomenon is slightly carried out, but the secondary collision phenomenon is not repaired under the condition of not influencing continuous use, and then the secondary collision phenomenon is carried out again. Research on this special case is much more rare, and how to perform experimental tests on it is also a major concern in the field of marine engineering.
