The performance of existing models to predict burst pressure of crack-like defects in low-toughness materials is not well documented and there is little guidance on which model to use or which safety factors to employ.
The joint industry project will provide a consistent analysis process for the evaluation of low-toughness materials, and a rigorous database of small and large scale tests resulting in calibrated safety factors for existing models.
Preventing unnecessary conservatism but also accounting for non-conservatism allows more targeted remediation and mitigation programmes for low-toughness materials.
Overly conservative predictions lead to additional excavations. Each non-necessary excavation redirects USD 25-30k to other integrity management programmes.
