Product inventory monitoring

A method for monitoring, determining, and initiating a fuel storage and refinery equipment inventory and maintenance needs, the method comprising:

• determining inventory reconciliation at one or more of a plurality of storage tanks, the inventory reconciliation including:
• capturing, in real-time, actual values of physical book data of the one or more of a plurality of storage tanks via tank gauge levels, the actual values indicating one or more properties of the inventory, the one or more properties including tank volume, tank level, rack meter values, pipeline movements, marine movements, or a combination thereof, and
• comparing the actual values of the physical book data with predicted values of the physical book data to detect a real-time deviation from the predicted values, the real-time deviation indicating a discrepancy in the one or more properties of the inventory;
• comparing the real-time deviation to a predetermined limit to detect a malfunction at the one or more of a plurality of storage tanks;
• comparing the malfunction at the one or more of a plurality of storage tanks with the discrepancy in the one or more properties of the inventory to identify one or more maintenance needs, the one or more maintenance needs including a thermal relief valve failure and a floating roof landing;
• and
• indicating the one or more maintenance needs responsive to the identification of the one or more maintenance needs.
