| 摘 要： | In this paper,an inner turret moored FPSO which works in the water of 320 m depth,is selected to study the so-called "passively-truncated numerical-simulation" type of hybrid model testing technique while the truncated water depth is 160 m and the model scale λ=80.During the investigation,the optimization design of the equivalent-depth truncated system is performed by using the similarity of the static characteristics between the truncated system and the full depth one as the objective function.According to the truncated system,the corresponding physical test model is made.By adopting the coupling time domain simulation method,the truncated system model test is numerically reconstructed to carefully verify the computer simulation software and to adjust the corresponding hydrodynamic parameters.Based on the above work,the numerical extrapolation to the full depth system is performed by using the verified computer software and the adjusted hydrodynamic parameters.The full depth system model test is then performed in the basin and the results are compared with those from the numerical extrapolation.At last,the implementation procedure and the key technique of the hybrid model testing of the deep-sea platforms are summarized and printed.Through the above investigations,some beneficial conclusions are presented.
