Scenario: Imagine you are working on an oil rig and a sudden increase in pressure is detected at the wellhead.
Task: Describe the steps you would take to address this situation, focusing on the role of the Master Valve.
Your answer should include:
Here's a possible solution:
Identify the Danger: A sudden pressure increase indicates a potential well blowout, which can result in uncontrolled release of oil and gas, leading to explosions, fires, and environmental damage.
Master Valve Action: Immediately activate the Master Valve to shut in the well, stopping the flow of oil and gas. If possible, use the choke valve to gradually reduce pressure before completely shutting in the well.
