In some situations, it may be necessary to verify the camera view captured by the LineVu system. To achieve this, follow the steps below to isolate the gas in the standoff and refocus the camera to confirm the view.
| Step ID | Task | Duration |
|---|---|---|
| 1 | Notify Process Vision Support about the timing of the valve closure so they can monitor or assist in real time. | - |
| 2 | Close the valve on the standoff | 10 mins |

| 5 | Reopen the valve slowly to avoid disturbing the camera with turbulent gas or mist. | 10 mins |
| 6 | Notify Process Vision Support again to refocus the camera on the pipeline floor and resume normal operations. | - |
If venting is not possible due to hazardous gas conditions:
