Semi-pressurized ships capable of withstanding carriage temperatures down to -104°C cannot carry which of the following cargoes?
Direct Answer
Option A: Methane (LNG)
Methane, the primary component of LNG, requires an extreme atmospheric boiling point of -161.5°C. Semi-pressurized ships capable of -104°C cannot carry LNG because their containment and insulation systems are incapable of reaching the cryogenic temperatures required for liquefaction.
