SENSITIVITY STUDY OF ENVIRONMENTAL LOAD TO RELIABILITY INDEX FOR MALAYSIAN REGION

Increased in environmental conditions, topside dead and live loads, material
deterioration, anomalies and neglected inspection schedules reduce the design
capacity of jacket platforms. For safe operation, review on current safety
performance ofjacket platform is mandatory. Component based analysis is no longer
adequate to give global safety status of ageing jacket platform. Push over analysis
coupled with reliability method and redundancy analysis, is the common approach to
analyze ageing jacket platforms in Malaysia. This study attempted to establish the
relationship between reliability index and return period for Malaysian region
reference.
