We study a delayed fuzzy 
$H_{\infty }$ control problem for an offshore platform under external wave forces. First, by considering perturbations of the masses of the platform and an active mass damper, a Takagi–Sugeno fuzzy model is established. Then, by introducing time delays into the control channel, a delayed fuzzy state feedback 
$H_{\infty }$ controller is designed. Simulation results show that the delayed fuzzy state feedback 
$H_{\infty }$ controller can reduce vibration amplitudes of the offshore platform and can save control cost significantly.
