| Summary: | Accidental vessel-platform collision can severely affect the integrity of a fixed platform. Due to lack of comprehensive studies, the currently used design guidelines often results in over conservative or under design of jacket platform legs for vessel impact loads. The number of accidental collision recorded in the recent past between vessel and platform is significantly high. Failure to identify and select proper design load can lead catastrophic accidents. The performance and structural response of variation diameter of jacket leg on vessel collision impact was not well studied in the past. The relationship between specification of vessel mass and indentation of jacket leg due to vessel impact is also required better understanding. In this research, numerical simulation was conducted to investigate different parameter associated with boat impact on jacket leg of a fixed platform. This research is expected to contribute a better understanding of the vessel-platform collision event in terms of various related parameters. This study has the potential to significantly contribute in idealising and selecting design impact load for jacket legs vessel impact in Malaysia oil and gas operation. |
