How to cool down cargo system in a liquefied gas carrier

Cargo systems are designed to withstand a certain service temperature; if this is below ambient temperature the system has to be cooled down to the temperature of the cargo before cargo transfer. For LNG and ethylene the stress and thermal shock caused by an over-rapid cooldown of the system could cause brittle fracture. Cooldown operations should be carried out carefully in accordance with instructions.
