Q

You are on an inerted tankship. A low pressure alarm must be set to cause an audible and visual alarm if the pressure in the tanks cannot be maintained at more than __________.

🔍 Key Concepts

• Inert gas system requirements for tankships under 46 CFR and SOLAS Chapter II-2 • Purpose of a low pressure alarm in cargo tanks using inert gas • Relationship between tank pressure and the vacuum/pressure relief settings

💭 Think About

• Ask yourself: Is this alarm meant to trigger at an absolute fixed pressure, or at a value related to another system setting? • Which choice is directly tied to protecting the tank from air ingress and loss of inert condition, rather than to fan capacity or scrubber performance? • Think about when you would want an EARLY warning that inert gas pressure is getting too low: how would that be expressed in these options?

✅ Before You Answer

• Verify in current 46 CFR and SOLAS II-2 what the low pressure alarm on inerted tanks is referenced to (fixed inches of water vs. percentage of a setting). • Check which options refer to actual tank protection settings (like relief valves) versus equipment operating points (like fan capacity or scrubber pressure drop). • Confirm that the alarm setting you choose would provide a safety margin before the tank reaches the point where outside air can be drawn in.
