- Abstract
- Continuous assessment of aged offshore structures is becoming extremely important to
avoid any hazardous consequences throughout their design life. In Malaysian waters
where most of the offshore structures are jacket platforms, it was found that many of these
structures are currently operating beyond their design life. With continuous corrosion
taking place, structural reliability and operation will be affected. Therefore, for the safety
evaluation, this study focuses on the reassessment of an existing aged jacket platform in
Malaysian waters pertaining to corrosion effect. In this study, pushover analysis was
carried out to determine the ultimate strength of the corroded jacket platform by
quantifying the reserve strength ratio value. Two different time-dependent corrosion
wastage models were used in the present study to simulate the corrosion behaviour at the
splash zone of the jacket platform. It was observed that average corrosion condition
relatively simulated the calm waters of Malaysia and by applying this corrosion, the jacket
platform can withstand the environmental load acting on it. The results developed in the
present study will be useful for future study in predicting and modelling corrosion
tolerance of jacket platforms in Malaysian waters.
