Pipeline Reliability Assessment For Interacting Corrosion Defect

Pipelines have been the most practical method to transport oil and gas in the industry. However, as the structure operates with time, it is exposed to many types of defects. One of the major threats to offshore pipelines has been corrosion. Corrosion deteriorates the integrity and structural strengt...
