🔍 Key Concepts

• Thermal expansion of petroleum products when temperature increases after loading • Requirements for cargo tank venting during loading of petroleum cargoes • Consequences of over-pressurizing or under-ventilating a cargo tank

💭 Think About

• What happens to a cold petroleum cargo as it warms up to ambient temperature during the voyage or alongside? • Which action, if skipped, could most directly lead to dangerous tank overpressure as the cargo temperature rises? • Are cargo tank vents on petroleum carriers normally sealed or designed to remain open/relieve pressure during loading and voyage?

✅ Before You Answer

• Verify how volume changes with temperature for petroleum cargoes (expansion on warming). • Check what proper cargo tank venting requires during loading flammable or combustible liquids (sealed vs. open/relief). • Confirm which listed measures are actually standard safety practices and which would be abnormal or unsafe during loading.
