Operational records → Inventories & LDAR has two tabs.
Inventory counts
Inventory counts feed count-based fugitive and pneumatic sources. Click New count and enter the Component, the Count and Valid from (the count applies from the first month starting on or after this date).
Count-based estimates need device and component emission factors in the reference library. Where the library has none for your equipment, the calculation reports a missing factor instead of inventing one; measured leak findings or metered pneumatic supply gas can be used instead.
LDAR findings
LDAR findings record leak surveys. Click New finding and enter:
- Survey date and Previous survey date;
- Component tag and Component type;
- Result: Leak found or No leak;
- for a leak: Leak rate, Unit, Gas and Measurement method (OGI estimate, Hi-flow sampler, Bagging, Other);
- Repair date, the location (Use my location on a phone) and a Photo.
A leak counts from the previous survey until the repair date. Without a previous survey date it counts from the month it was found.
LDAR programme
Operational records → LDAR programme tracks your leak detection and repair programme: which components are surveyed, how often, and whether each leak found is repaired in time.
- Survey plans: one per asset, or per source of an asset. Choose the Survey method (a label: OGI, Method 21, AVO, continuous monitoring or other), the Frequency (every so many months or days), the Repair window in days and the First due date. Your organisation sets these values; EmitLedger does not fill in regulatory frequencies or deadlines. Use Requirement followed to note what the plan is based on.
- Next due: the last completed survey plus the frequency, or the first due date when no survey is completed yet. Plans show Overdue, Due soon (within 30 days) or Scheduled; paused and retired plans have no due date.
- Surveys: record each survey as Planned, Completed or Cancelled, with the surveyor and the number of components surveyed. A completed survey is on time when it was completed by the date it was due when recorded.
- Open repairs: when a finding is linked to the survey that found it (Survey in the finding dialog on Inventories & LDAR), its repair is due the survey date plus the plan’s repair window. A repair is Open, Overdue, Repaired or under Delay of repair. Record a delay with its reason and, optionally, a new date; you can withdraw it later.
- KPIs: surveys on time, open leaks, median repair days (for repairs in the last 12 months) and overdue surveys.
Members who can enter data receive a weekly email (and a mobile notification) listing overdue surveys and repairs for the assets they can see.
