Question 1533Deck General70% to pass
Under which of the following conditions will the blowers of an inert gas generation system aboard a tanker remain operational?
AI Explanation
The correct answer is C) The tank atmosphere above 8% oxygen.
The blowers of an inert gas generation system aboard a tanker will remain operational when the tank atmosphere is above 8% oxygen. This is because the inert gas system is designed to maintain the tank atmosphere below 8% oxygen to prevent the risk of explosion. When the oxygen level exceeds 8%, the blowers need to continue operating to supply the inert gas and reduce the oxygen content to a safe level.
The other options are incorrect because they do not reflect the primary purpose of the inert gas system, which is to maintain the tank atmosphere below 8% oxygen. High oxygen levels in the boiler combustion (option A), high inert gas temperature (option B), or loss of cooling water supply (option D) would not trigger the blowers to remain operational if the tank atmosphere is below 8% oxygen.
