Which of the following describes excessive recirculation of inert gas?
AI Explanation
The correct answer is C) it is undesirable and it may lead to high oxygen content of the inert gas.
Excessive recirculation of inert gas is undesirable because it can result in a higher oxygen content in the inert gas. This is problematic because the purpose of using inert gas is to maintain a low-oxygen atmosphere in the cargo tanks to prevent the risk of explosions. If the oxygen content of the inert gas increases due to excessive recirculation, it may no longer be effective in providing the necessary inerting of the cargo tanks.
The other options are incorrect because: A) over-pressurization of cargo tanks is not the primary concern with excessive recirculation, and B) overheating the deck water seal is not directly related to the issue of excessive inert gas recirculation.
