Pushover Analysis for Jacket Platform Sensitivity Study and Safety Ratios
Most of the jacket platform in Malaysian water has exceeded their design life, mainly due to the demand of continue usage to further extract oil from the reservoir. Hence, the reliability of the jacket platform has to be assessed to ensure they are fit for future operation despite aging problem....

| 總結: | Most of the jacket platform in Malaysian water has
exceeded their design life, mainly due to the demand of continue
usage to further extract oil from the reservoir. Hence, the
reliability of the jacket platform has to be assessed to ensure they
are fit for future operation despite aging problem. Pushover
analysis will be performed on jacket platform to obtain Reserve
Strength Ratio as an indicator of the reliability of the jacket. The
significance of parameters such as pile soil interaction, wave
direction and platform’s geometrywas studied in a sensitivity
study. This paper discusses the parameters that bring significant
effects on the value of Reserve Strength Ratio. Besides, author
also assess the effect of damaged members on the platform’s
ultimate capacity and produce other safety indicator other than
Reserve Strength Ratio to better describe the safety of a jacket
platform. |
