The blowers of an inert gas generation system aboard a tanker, will be automatically secured if _______________.
AI Explanation
The correct answer is D) all of the above.
The blowers of an inert gas generation system aboard a tanker will be automatically secured if any of the following conditions occur:
1) The normal water supply at the water seal is lost, as this could allow backflow of flammable cargo vapors into the inert gas system.
2) The cooling water supply to the scrubbers is lost, as this could allow the temperature of the inert gas to rise excessively.
3) The temperature of the inert gas being delivered to the cargo tanks exceeds 150°F, as this could pose a risk of ignition or damage to the cargo tanks.
All of these conditions could compromise the safe operation of the inert gas system, so the blowers would be automatically shut down to prevent any potential incidents.
