The ongoing cleaning program (pigging) on the Husky lateral is unlikely to effectively mitigate these same sharp deep anomalies because the brushes would not be expected to penetrate to the bottom of these pits to arrest the active corrosion. Since 2007, Express Pipeline has completed numerous digs and repairs on the 1.3 kilometer pipeline and spent in excess of $4.3MM in repairs and inspections. It is evident that the Husky lateral’s internal corrosion problem cannot be effectively mitigated by combining regular cleaning with periodic ILI, and that this line should remain out of service until a more effective program is implemented or the line is replaced.The application can be viewed at: Express Pipeline Abandonment.
