Kuwait Oil Company (KOC) is responsible for exploration, production and exporting crude oil in the State of Kuwait. As part of the Company's expansion to increase the production, several new pipelines have been constructed. At the export tank farm storage area, four new filling pipelines were commissioned in 2009 as these pipelines are strategically important for sustaining crude oil export. In May, 2014, a leak was reported in a 34 (863 mm) diameter pipelines due to internal corrosion and subsequently three more leaks occurred. Moreover, another 34 (863 mm) diameter pipelines leak was reported during the same period. Since the pipelines leaked after a short span of 5 years in operation, it was considered a serious threat, both pipelines were inspected by using ultrasonic ILI tool where severe internal corrosion damage was detected. This necessitated further investigations to determine the root-cause of the internal corrosion, so that remedial measures can be taken. Internal Corrosion Direct Assessment (ICDA) methodology was utilized to determine the root-cause of the internal corrosion of the filling pipelines. This paper describes all the activities that have been carried out determine the root cause. 2018 by NACE International.
