Examples of OTS issue findings
In this section, we will show some examples from real projects of some issues that were found on the OTS and fixed, saving the contractor time and money and avoiding potential safety issues.
Potential safety incident
In a specific project, we simulated fire in an area and tried to test that on the simulator. When the first malfunction was activated, the control system issued a trip and blowdown command. In this case, all the gas in the pipes would be flared, but the last thing you'd want is to release flammable gas when there is a fire nearby.

In this case, a...
