An inert gas system incorporating a separately fired inert gas generator shall be provided with visual and audible alarms to indicate failure of the power supply to the generator, the automatic control system, and __________.
ā¢ Inert gas systems on tankers and their safety functions ā¢ What specific failures must trigger alarms under SOLAS and 46 CFR ā¢ Difference between normal process variations (temperature, fuel rate) and critical safety interlocks
ā¢ Which of these options, if it failed, would most directly threaten the safe operation of the inert gas generator or the protection of cargo tanks? ā¢ Think about what the inert gas generator absolutely needs to keep running safely and prevent overheating or damage. ā¢ Which parameter is most likely to be continuously monitored as part of a basic safety interlock system rather than just process optimization?
ā¢ Verify in 46 CFR and SOLAS requirements for inert gas systems what items MUST have alarms on separately fired inert gas generators. ā¢ Ask yourself which option, if lost suddenly, could quickly lead to equipment damage or unsafe gas delivery to cargo tanks. ā¢ Eliminate options that are more about efficiency or performance rather than core safety protection.
