| No. | Factor/Aspect | Reference | Cracking Probability | Score |
| 1 | Leaks | Historical records | Very high failure probability | 100 |
| 2 | High hardness in the base material (susceptible material) | Metallographic analyses laboratory/field | High failure probability if stress levels are increased | 80 |
| 3 | By force withdrawn/ installed sections (high stress levels) | Field works | High failure probability | 80 |
| 4 | Linearity recovery of withdrawn pipe sections (high stress levels) | Field works | Very high failure probability | 100 |
| 5 | Identified cracks | Metallographic analyses laboratory/field | High failure probability | 100 |
| 6 | High stress level sites | Flexibility analysis | Intermediate failure probability if combined with susceptible materials | 50 |
| 7 | Sites with high displacement | Flexibility analysis | Intermediate failure probability if combined with susceptible materials | 50 |
| 8 | Sites with varying stress level | Flexibility analysis | High failure probability if combined with susceptible materials | 80 |
