🔍 Key Concepts

• Liquefied flammable gas (LFG) tanks and how they are protected from overfilling • The role of the safety relief valve (pressure protection) versus level gauging devices (volume/level control) • Which documents or instruments are used for planning cargo versus controlling the actual loading in real time

💭 Think About

• Ask yourself: which option is directly tied to the physical design limits of the tank and gives you a real-time indication while loading? • Consider whether pressure protection (relief valves) or level indication is normally used to decide when to stop loading a liquid cargo tank. • Think about which choice is a planning reference and which is an operational stopping point during cargo loading.

✅ Before You Answer

• Verify which device or limit is intended to prevent overfilling rather than just overpressure. • Confirm that the method you choose would still be valid if cargo temperature or density changes, since LFG volume can change with temperature. • Make sure the option you pick is something the tanker crew can observe and act on immediately during loading, not just a document prepared beforehand.

The amount of LFG that may be loaded into a given tank is determined by __________.

checking the loading sheet

loading to within 1% of outage

loading to within 10% of the safety relief valve setting

filling to the maximum level indicated on the liquid level gauging device
