Abstract

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.
