🔍 Key Concepts

• P-tank system purpose – how pressure/vacuum cargo (like LPG/LNG or certain chemicals) is stored and controlled • Difference between normal operating pressure and relief/safety device settings • Role of safety valves and pilot unloading valves in protecting the tank from overpressure

💭 Think About

• Ask yourself: Should normal operating pressure ever be as high as the pressure needed for cleaning or repressurizing the system? Why or why not? • Think about where, relative to the safety or relief devices, it is safest to keep the normal operating pressure so the protection devices don’t lift in routine operations. • Consider how a pilot unloading valve or safety valve is supposed to function: are they for everyday control of pressure, or for abnormal/high‑pressure situations?

✅ Before You Answer

• Verify that normal operating pressure is set so that relief/safety devices will not lift during normal service. • Check which device (safety valve vs. pilot unloading valve) is intended as the primary overpressure protection, and where operating pressure should be in relation to that setting. • Eliminate any choice that would cause the tank to operate too close to or above the relief/protection settings during routine cargo operations.
