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.
