Starting from the motion equations and accepting the technique of numerical variational adjustment, this paper sets up a new model to calculate the typhoon wind field in the Bohai Sea.

Analysis of three-dimensional models under in-service wind speed, out-of-service wind speed and typhoon wind speed is carried out to study the wind-induced vibration response of gantry crane.

Then, the response of the SCS to Typhoon Imbudo is examined using POM model, which is driven by the wind stress calculated above by the wave model.
