oa Integrated Meteorological and Geohazard System Advisory (iMGESA) for Pipeline Integrity

The integrity of onshore pipeline systems is a crucial element for oil and gas companies, including PETRONAS. Geohazards, ground movements, and severe metrological conditions of the environment can cause lots of risk to the onshore pipelines. Natural events including landslides, flooding, slope creep, subsidence, and seismic activities increase the potential for pipeline failure rates throughout the development and operation stages. To address these challenges, a data-driven solution called Integrated Meteorological-Geotechnical System Advisory (iMGESA) has been developed. iMGESA is an in-house risk assessment tool that uses machine learning models to predict the probability of geohazard impact on pipeline failure. It incorporates data from SSGP (Sabah Sarawak Gas Pipeline) Pipeline conditions, rainfall data, and geographical properties to generate outputs including probability of landslide, risk index for geohazard impact to pipeline (target PR), and geopig strain.

The objective of iMGESA is to provide accurate and early intervention on the effect of rainfall on terrain degradation and to prevent further deterioration of geohazard conditions at sites. Additionally, a dashboard system and an online platform have been developed to leverage automation and advanced analytics to generate timely reports on terrain health status at PETRONAS onshore pipeline assets, which staff can access at anytime from anywhere.
