OSPAR 30'' displacement; Esvaziamento do OSPAR 30''

Abstract

Crude oil pipeline OSPAR that unites Sao Francisco do Sul-SC to Araucaria-PR, with 30 inches in diameter and extension of 118 km (74 mi) was displaced in May 2004. Nitrogen at high flow rate and a pig were used to remove the crude oil, liberating the line to maintenance. Logistic restrictions prevented that the displacement followed the normal flow direction, so the option was to do the job in the reverse direction. To make viable our operation, a maneuver was performed; which we suppose was never done before in Brazil, at an intermediate pumping station, allowing a pressure reduction at the line end, maintaining it at permissible levels. Despite logistical and operational difficulties, the job was performed with success in 47 hours. (author)
