Creating a Gas Recovery Transaction

The gas recovery transaction records instances where gas is removed from an asset (such as a circuit breaker) and returned to the container, for example, when the equipment is being decommissioned.
In our examples, the transaction requires a container ID, the asset that the gas is recovered from, the container weight as measured after the recovered gas is added, and the recovery type. You can also specify whether the container is being decommissioned. Optionally, you can record a transaction description and the scale used to weigh the container.
Gas recovery can represent a loss of gas that needs to be reported. In this example, APM creates a gas loss transaction (leak to atmosphere) with the value “Gas weight loss” when the transaction is saved. APM calculates the gas weight loss value by subtracting the transaction gas weight from the equipment capacity. Consequently, you must also enter the equipment capacity in the transaction. The Leak to atmosphere transaction shows the gas loss value in the Adjustment value box.
Note: Transaction types and their requirements are defined to your organization’s specifications, so the example transaction in this topic might differ from what you see in APM.
This topic explains how:

To Create a Gas Recovery Transaction

1.
In the Site window, select the Regulated Gas Management view and the Transactions tab.
2.
On the By Asset or By Asset Map Location tab, select the asset from which the gas has been recovered. Click New. The Gas Transaction window appears.
Tip: You can also create a transaction from the Asset window. Select the Regulated Gas Management view, Gas Transactions tab and click New.
Note: The transaction is assigned to the asset’s site by default. The transaction site is shown on the Details tab, along with the transaction details.
3.
In the Transaction type list, select “Gas Recovery”.
4.
The Transaction tab appears with changes based on the transaction type’s requirements. For example:
If the transaction type is assigned a default gas type, it is selected in the Gas type box.
5.
In the Container list, select the gas container.
The maximum and tare weights are copied from the container record, as well as the previous weights.
6.
7.
In the Equipment decommissioned list, select the appropriate value.
8.
In the Weight as measured box, enter the weight of the container after the recovered gas has been added.
APM calculates the transaction gas weight: the weight as measured is subtracted from the previous weight as measured. This is the weight of the gas that was recovered from the asset, which is shown as a negative number.
APM calculates the container gas weight (amount of gas left in the container) by subtracting the tare weight from the weight as measured.
9.
In the Equipment capacity box, enter the amount of gas that the asset can hold.
10.
In the Scale list, select the scale used to weigh the container.
11.
The Performed on and Performed by boxes are populated automatically. You can change the values if required.
Note: If the performed-on date is prior to the container’s most recent transaction, Transaction gas weight is replaced by the message “Calculation pending”. When you click OK to save the transaction, the transaction gas weight is calculated and the transaction tables and windows are updated. This allows APM to ensure that the most recent performed-on date is taken into consideration.
Tip: If you wish to confirm gas transaction weights, select one or more transactions in any tab under the Transactions tab. Right-click and click Calculate Transaction Quantity.
12.
13.
Click OK. The dialog closes and the transaction is added to the tab. The leak to atmosphere transaction is also added to the tab.

To View Information about the Gas Loss Transaction

1.
Open the Gas Transaction window for the gas recovery transaction and select the Details tab. The Gas loss transaction area shows the Leak to atmosphere transaction:
2.
Select the Details tab to see the transaction type that generated the secondary transaction.
