摘要：
Combined with the model test, based on the numerical reconstruction of the computational model, the time domain full coupling analysis method is used to explore the influence of the operating water depth on the air gap of floating platforms. The influence of operating water depth on the stiffness and mooring force of mooring system of floating platforms is analyzed, and the mechanism of influence on air gap is revealed. The results show that the negative air gap of the studied floating platform is sensitive to the water depth, and the energy spectrum of the platform's motion response is significantly affected by the operating water depth. The negative air gap increases with the increase of water depth. With the increase of water depth, the stiffness of the mooring system decreases, the recovery force of the platform becomes weaker, the motion of the platform increases, and the vertical displacement of the platform changes and the probability of negative air gap increases. Wave slamming caused by the variation of water depth seriously affects the safety of platform operation. The effect of operating water depth on the air gap movement of platforms should be fully considered in practical engineering design. © 2019, Editorial Board of Journal of Ship Mechanics.
