Shutdown of air cooling unit drives

Event description
Following a cyberattack, one of the largest oil and gas companies in State F has temporarily reduced its supply of liquefied natural gas to the market. The intruders gained access to the automated control system of the air cooling unit and disabled the drives, leaving the unit unable to release excess heat into the atmosphere. While the operator was figuring out the cause of the malfunction, the temperature inside the compressor unit soared to a critical level, resulting in an emergency shutdown of the compressor. The liquefied natural gas plant is now closed for unscheduled maintenance, and the company is facing significant losses due to the downtime.
