A fuel terminal loses money in the gap between what the paperwork says it holds and what the tanks actually hold. OML is the layer that closes that gap: inventory, movements, loading and reconciliation in one record, tied back to the measurements they came from.
The problem it addresses
Symptom
Underlying cause
Book stock and measured stock disagree
Inventory read at one moment, movements recorded at another, nothing reconciles the two
Losses cannot be attributed
A discrepancy is known in total but not by tank, product or movement, so it gets absorbed rather than investigated
Loading disputes
No single record linking an order, the meter reading and the vehicle that left
Month-end takes a week
Data is assembled from gauging screens, meter printouts and spreadsheets by hand
What the system covers
Area
Function
Tank inventory
Level, temperature and calculated volume across the tank farm, with volume correction applied consistently
Movements
Receipts, internal transfers and outbound loadings recorded against the authorisation that permitted them
Loading operations
Gantry and berth activity linked to orders and to custody transfer records
Reconciliation
Book against measured, with the difference broken down rather than absorbed into one number
Reporting
Stock position, throughput and loss reporting on the terminal’s own cycle
What it reads from
Source
Data
Tank gauging system
Level, temperature, water level
Metering
Flow and totalised quantity at receipt and loading points
Control system / PLC
Valve line-up and pump status, so a movement is recorded against the route it actually took
Terminal automation or business system
Orders and authorisations, where one exists
Scope boundary
Included
Not included
The information layer: acquisition, records, reconciliation, reporting
Tank gauging and metering hardware
Interfacing to gauging, metering and the control system
Custody transfer certification and metrological approval
Cabinet build and system integration where the project needs it
Terminal commercial operation
