Narrative
On 11/3/2015, an oil and gas company pumper (third-party) reported to US a small dry ice ball on the surface above our buried texok CO2 pipeline. Operator personnel located and confirmed the dry ice ball. The area around the dry ice ball was secured, and there was no plume or gaseous emission of CO2 from the pipeline. The release did not result in explosion, fire, death, personal injury, significant property damage, or pollution of any water body, and the release was confined to the pipeline right of way. The CO2 source plant was notified and shutdown, and the leaking pipeline segment was blow down after isolating the segment by closing the upstream and downstream valves. Upon excavation, the coating was found to be loose from the pipe and a pinhole leak was found within a few inches of a girth weld. A portion of the pipe containing the leak and weld was cutout and removed, and was replaced with pre-tested pipe. X-ray of both welds was accepted. On 11/4/2015, welds were doped, and the pipeline was purged with CO2 by opening the upstream valve. Valves were opened and the CO2 source plant was restarted, returning the pipeline to regular service in a safe manner. The dig hole was backfilled without incident.
