Integrity assessment of corroded pipeline using in-line inspection data

Oil and gas pipeline operation is one of the highest risk systems in the industry. Any failure of the system will cause a huge impact to the environment and economy. The integrity assessment of the oil and gas pipelines in Malaysia has been focused and discussed long time ago. Formerly, the inspecti...
