Predicting Extreme Dynamic Response of Offshore Jacket Platform Subject to Harsh Environment

Offshore jacket platforms (OJPs) may be exposed to harsh environmental conditions during their operation in different return periods. It is necessary evaluate the dynamic performance of OJPs subjected extreme wave loadings secure a safe operation. In earlier studies, various approaches were introduced analyze response an OJP sea states. However, serious shortcoming proposed methods computationally time consuming and requires considerable amount simulations OJP. Accordingly, these would not realistically. this study, subject environment evaluated considering time-domain simulation. The developed model will result more realistic by simulating whole structure 1800 seconds loading light randomness. application methodology demonstrated assessing fabricated North Sea. analysis shows that among all assigned probability distribution functions (PDFs), most suitable for predicting maximum deck displacement periods was generalized value (GEV). Moreover, results show likely remain limit condition id="M2"> 1 -year period. contrast, other periods, exceed condition. method beneficial future risk reliability analyses require great deal data derived from numerical simulations.
