Component Reliability Prediction Model for Malaysia Offshore Regions Static and Regression Analysis

Abstract—Majority of the fixed jacket platforms installed in
Malaysia water regions had already exceeded their design life.
In order to prolong the service life of these aged platforms,
their current structural integrity conditions need to be
reviewed. System reliability governs the reliability of a
structure. However, a system is consisted of many
components. Combination of individual (component)
reliability in dominant failure path(s) explains the system
reliability. As oppose to the system reliability assessment
method, generation of component reliability is much simpler.
This paper presents the methodology for computing a
simplified component reliability model. Interpolation methods
for obtaining the met-ocean design values at different return
periods are discussed. Also, effects of different met-ocean
combinations are studied.
Keywords—component reliability; met-ocean; interpolation
