🔍 Key Concepts

• Carriage of coal cargoes and associated hazards (methane emission, self-heating, oxygen depletion) • Differences between anthracite and bituminous coal in terms of gas emission • Standard guidance on ventilation of coal cargoes and whether surface ventilation is recommended or restricted

💭 Think About

• Think about which type of coal is ‘harder’ and more carbon-rich, and how that affects the amount of methane it can give off compared to softer coals. • Consider whether wetness is always unsafe, or whether coal is often loaded damp and managed with other precautions. • Ask yourself what the main corrosion agents are in coal cargoes: is methane the real culprit, or are other compounds more responsible?

✅ Before You Answer

• Verify which coal type (anthracite vs bituminous) is typically associated with higher methane emission risks. • Check whether guidance for methane-emitting coal emphasizes surface ventilation of the hold, avoiding air channels through the body of coal, or the opposite. • Confirm what substances from coal cargoes are known to accelerate corrosion of ship’s structure (e.g., sulfur compounds) and whether methane plays that role.
