A method for operating a cryogenic plant using an online real-time monitoring and diagnostic system that continually compares actual versus expected plant key performance indicators, alerts operating personnel to any significant performance shortfall, assists in required diagnostics, and suggests corrective actions, preferably using a top-down diagnostic tree methodology that presents calculated key performance indicators to the operator in a manner which logically flows from plant overview to detailed breakdown by plant area and equipment component.
