Calculators
You’re the one who keeps things safe, efficient, and within spec. That’s why we built these calculators – for professionals who don’t have time to dig through spreadsheets or second-guess numbers.
On-site or in the control room, get instant clarity on what matters: degradation, inspection intervals, corrosion rates, and asset life.

What you can calculate (Fast)
How to Use the Calculator
Last Inspection Date
Enter the date of your last inspection.
Current Wall Thickness
Provide the current wall thickness of your component.
Renewal Thickness
Provide the wall thickness at which the component must be renewed.
Corrosion Rate (mm/year)
Input the corrosion rate, based on previous inspection data or estimates.
Results You’ll Get
Remaining Corrosion Allowance: Difference between current and renewal thickness.
Remaining Life Date: Estimated date the component reaches minimum thickness.
Next Inspection Date: Suggests when to perform next inspection.

How to Use the Calculator
Wall Thickness 1 (mm)
First measured wall thickness (older date).
Measurement Date 1
Date of the first measurement.
Wall Thickness 2 (mm)
Second measured wall thickness (newer date).
Measurement Date 2
Date of the second measurement.
Results You’ll Get
Corrosion Rate: Calculated annual rate of material loss.

Last Assessment Date
Enter the date of your most recent pipeline inspection.
Remaining Corrosion Tolerance (mm)
How much wall thickness your pipeline can safely lose.
Future Corrosion Rate (mm/year)
Expected corrosion rate based on history or estimates.
Results You’ll Get
Remaining Life Date: Estimated date the pipe reaches limit.
Remaining Life (years): Safe operating years remaining.

How to Use the Calculator
Current Wall Thickness (mm)
Enter the current wall thickness measurement of the component.
Renewal Wall Thickness (mm)
Enter the wall thickness at which the component should be renewed or replaced.
Results You’ll Get
Remaining Corrosion Allowance: The difference between current and renewal wall thickness values.

How to Use the Calculator
Sensor Subsystem Type
Select the Sensor Subsystem Type (SIF configuration) from the list (e.g., 1oo1, 1oo2, 2oo3).
Dangerous Undetected Failure Frequency (λdu)
Enter the frequency of dangerous failures undetected by diagnostics but discovered during proof testing (e.g., per hour or per year).
Testing Interval (Ti)
Enter the time between proof tests when undetected failures accumulate, using units consistent with Failure Frequency (e.g., hours or years).
Results You’ll Get
Average Probability of Failure on Demand (PFDAvg):
The average probability that the Safety Instrumented Function (SIF) will fail upon demand over the specified Testing Interval (Ti).
Average Risk Reduction Factor (RRFAvg):
A measure of how much, on average, the SIF reduces the risk of failure.
Safety Integrity Level (SIL):
The safety level assigned to your SIF based on the calculated PFDAvg, indicating its reliability.

Equipment Failure Cost:
Enter the total cost of equipment failure.
ETBF:
Time (in years) until failure without maintenance.
ETBC:
Time (in years) until failure with maintenance.
Expense per Maintenance Occurrence:
Cost of each maintenance event.
Maintenance Occurrences per Year:
How many times maintenance is done yearly.
