To carry out joint mapping
-
Tap
and select Pipeline tally / Joint mapping.
An empty joint map record appears.
- Select the mapping method: WELD, LOOSE END, or BEND.
- Make sure the arrow on the Direction button matches the direction that joint mapping will be carried out along the pipeline. Tap the button to toggle the direction between downstream
and upstream
.
- If you are mapping welds, tap Options and select whether the next default weld ID should increase (for downstream joint mapping), decrease (for upstream joint mapping), or select no default.
-
Enter the ID of the weld, bend, or loose end, and the IDs of the associated joints.
- To check the details of the joint, tap Details. See To update joint details.
- To capture additional details relating to welds or bends, add extra fields to the form. See To add weld or bend information fields.
- Tap Add to store the joint map record.
A new joint map record appears. If you are working:
- downstream along the pipeline, the joint ahead previously entered is now the joint behind
- upstream along the pipeline, the joint behind previously entered is now the joint ahead
- The joint behind and joint ahead fields are not automatically filled out if the previous joint map record contains joint IDs that do not exist in the tally file.
- The software warns if you enter a joint ID that has already been used. If required, dismiss the warning and continue to store the record.
- You cannot store a weld that has the same joint ID entered in the joint ahead and the joint behind fields. When dealing with loose ends, leave one of the joint fields empty.
- To exit the screen and return to the map, tap Esc.
- To quickly change between mapping welds, bends, or loose ends, tap the arrow next to the ID field and then select Next ID of the required type.
- Tap the Prev or Next softkey to view the next or previous joint map record for the pipeline. This enables you to view joint map records in the order that they are used in the pipeline. The order is determined by the IDs entered in the joint behind and joint ahead records and is continually updated as you add new joint map records.
- To delete a joint map record or change the ID assigned to the joint map (for example, if you enter the incorrect ID), enter the ID to load the record and then use the appropriate softkey to change or delete the record.
- To swap the joint behind ID and the joint ahead ID, tap Swap.
- If a weld has been cut out and replaced with a new weld but you want to keep the original joint map record, tap the weld icon
next to the Weld ID field. The icon changes to the cut out weld icon
. Tap Update. The "cut out" weld record is moved out of the joint map sequence and added to the end of the joint map list so that it is available to reference and for reporting. When you create the joint map record for the replacement weld, enter the new weld ID and the appropriate joint IDs so that the joint map record references the same behind and ahead joints as the cut out weld.
