An LNG vessel contaiment system must be cooled down prior to loading cargo. Where are the cool-down parameters and rates obtained from?

Correct Answer: Option A — the instruction manual provided by the manufacturer of the containment system

Manufacturer instructions provide the precise engineering limitations, thermal stress thresholds, and mandatory cool-down rates for liquefied natural gas containment systems. Relying on the official instruction manual ensures structural integrity is maintained during initial cargo tank chilling.
