Abstract

The invention discloses a method for rapidly calculating the stability of a column-stabilized semi-submersible floating fan. The method comprises the following steps: S1, calculating the wind tilting moment of the column-stabilized semi-submersible floating fan; s2, the restoring torque of the column stabilizing type semi-submersible floating fan is calculated; and S3, checking the stability of the floating fan through the wind tilting moment and the restoring moment. According to the invention, the stability of the floating fan can be evaluated quickly.
