Jim Chappell, AVEVA, USA, explains why digital twin technology can be a game changer when it comes to maximising LNG operations and boosting plant profitability.

overnment policies and operating company sustainability initiatives encouraging transition to clean energy have led to an increase in demand for natural gas, leading to tight market conditions. However, with adequate supply sources in most producing regions around the world and a need to deliver increasing amounts of LNG to regions short in natural gas, there will be significant opportunity to fully utilise the maximum capacity of liquefaction plants when markets favour suppliers. To stay ahead of the game, maximising LNG production at lower cost is imperative for companies to sustain profitability in this competitive market.
