🔍 Key Concepts

• Cargo tank venting systems on tank vessels carrying petroleum products • Difference between a simple opening (like ullage or sounding pipes) and a safety relief device • Why tanks need protection from both over-pressure and vacuum during loading/unloading

💭 Think About

• Which device in the options is specifically designed as a safety control to protect the tank structure when loading or discharging, rather than just providing access or connection between spaces? • When you rapidly load or discharge petroleum, what happens to the air/vapors in the tank, and what kind of fitting is required by regulations to handle that safely? • Which choice is commonly mentioned in tanker construction/venting regulations in 46 CFR and SOLAS for protection of cargo tanks?

✅ Before You Answer

• Identify which option is designed to relieve both positive pressure and negative pressure (vacuum) in the tank atmosphere. • Eliminate any option that is mainly an access opening (for measuring/inspection) rather than automatic over-pressure protection. • Check your tanker safety notes: what specific valve name is tied to cargo tank venting arrangements for oil/petroleum cargoes?
