✍️ Sample Tanker Familiarization Questions & Answers
1. LPG carriers transport cargo such as propane and butane in what condition?
LPG is carried either fully pressurized, semi-pressurized/semi-refrigerated, or fully refrigerated as a liquid to keep it in a manageable state.
2. A Panamax tanker is dimensionally constrained by:
Panamax tankers are designed with maximum dimensions (approximately 294.1 m length, 32.3 m beam) to fit through the original Panama Canal locks.
3. What does the term 'ullage' refer to in cargo measurement?
Ullage is the empty space above the liquid in a tank, measured from the reference point at the top; cargo volume is calculated from ullage tables.
4. Which fire extinguishing agent is most appropriate for a Class B (flammable liquid) cargo fire on a tanker?
Class B fires require agents that smother, cool, or interrupt combustion—CO₂, dry chemical, and foam are all effective and standard tanker firefighting agents.
5. What should be the first step when a tanker begins to take on water due to a hull breach?
When a tanker begins to take on water due to a hull breach, the first critical step is to activate the bilge pumps to remove the ingress of water. This action helps control the flooding, maintain the vessel's stability, and reduce the risk of capsizing or further damage. It buys valuable time for the crew to assess the breach and implement damage control measures.
6. What is the primary purpose of an inert gas system on a tanker?
Inert gas systems replace oxygen in cargo tanks with non-flammable gas (typically flue gas or nitrogen) to prevent explosive mixtures from forming.
