Abstract

Abstract—Malaysian Oil and Gas Industry has been well established in the region. Over the years of producing oil and gas, the majority of jacket platforms in Malaysia have been encountering reliability issue due to aging and increasing environmental loading. Hence, there is a necessity to address the reliability of the jacket platforms in Malaysia. Authors have been studying on the current practice of reliability assessment method which is conducting pushover analysis on one particular platform at a time using all the updated and available data after investigations. This practice is time consuming and costly. By utilizing results from pushover analysis from platforms all over Malaysian waters, authors use regression analysis to produce a simplified reliability model. Considering the parameters such as water depth, air gap, storm wave height, braces system and regions, authors conducted regression analysis to obtain the Reserve Strength Ratio value as a reliability indicator. This could help to minimize time and cost needed for reliability assessment, provided the coefficient of determination is high. Keywords—Reliability, Pushover Analysis, Reserve Strength Ratio, Regression.
