Moomba –Adelaide Gas Pipeline, 2025 Fitness for Service and Corrosion Growth Prediction:
The 781 km, 22-inch Moomba to Adelaide Gas Pipeline (MAP), constructed in 1969, exemplifies the challenges of maintaining pipeline integrity over decades. Protected against external corrosion by a combination of field-applied tape coating and an impressed current cathodic protection system, the pipeline has been subject to ongoing evaluation and maintenance.
Fitness for Service and Corrosion Growth Modeling IICORR conducted a comprehensive fitness-for-service assessment and corrosion growth modeling for the MAP. The objective was to predict when individual external corrosion defects or clusters of interacting anomalies would reach critical thresholds: either a depth exceeding 60% of the nominal wall thickness or an estimated remaining strength factor (ERF) ≥0.99. This analysis supports a 20-year repair prediction program, enabling proactive maintenance and ensuring pipeline safety.
In-House Developed Software IICORR has developed proprietary software for burst pressure calculations, fitness-for-service evaluations, and corrosion growth analysis. This cutting-edge software is compatible with the ILI tallies provided by leading inspection companies, including ROSEN, TD Williamson, 3P Services, A-hac, Baker Hughes, …. Our software’s advanced capabilities streamline data analysis and ensure precise assessments.
