Abstract

Offshore pipeline plays an important role in oil and gas industry. It is considering as the most favored transportation mode of crude oil in large quantity. Throughout the years, there are a lot of pipeline accidents caused by metal cross section losses due to the internal corrosion. Therefore, pipeline operators have practiced reliability-based corrosion management programs which consists three components in managing their pipeline which are in-line inspection, pipeline reliability evaluation and pipeline repair. In order to determine the pipeline reliability, there are two approaches that practiced which are deterministic method and probabilistic method. ASME B31.G and P-F interval model are example of deterministic approach. Meanwhile, degradation analysis is the example for probabilistic approaches in determining the remaining pipeline life. This study explores both methods applied on offshore pipeline by using Intelligent Pigging (IP) inspection data. The objective of this study is to determine the offshore pipeline remaining life using PF-interval model and degradation analysis. The result from both methods is compared with the result generated by ASME B31.G. The result showed that degradation analysis more conservative than ASME B31.G and P-F interval since it was provide shorter mean life period.
