C2024-20909 Rehabilitation Of Existing 49 CFR 195 Pipeline Using Steel-Reinforced Thermoplastic Pipe

David Gregory, Shawn Poworoznik - This paper highlights a successful rehabilitation of a 49 CFR 195 regulated steel line in southern Louisiana. The status of the pipeline after one year of operation is detailed, providing updates to product integrity, results of scheduled material testing, and economic benefits realized by the Operator.The pipeline traverses a navigable waterway and rehabilitation using steel-reinforced thermoplastic pipe was approved by both state and federal pipeline safety administrations. Upon completion, the rehabilitated system restored crude transmission while also reducing overall operating risk. Use of the flexible steel pipe allowed the operator to utilize a dual-containment design and implement real-time continuous annulus monitoring on multiple interfaces, effectively reducing risk to the environment and residents.
