This paper presents a numerical study of ringing and springing response of a relatively new Offshore Triceratops. The platform is subjected to irregular waves using JONSWAP spectrum by varying the significant wave height, average wave period, vertical asymmetric factor and the over shoot parameter. Strongly asymmetric waves, which are capable of causing impact loads on triceratops, are used to simulate ringing in offshore triceratops. Heave response shows bursts but there are no rapid built ups. Gradual decay, which is seen in the present case, resembles a beat phenomenon.
