Maximising LNG Production with Digital Twin Strategy

By Bill Poe and Eddy Lek

Leveraging Digital Twin Strategy to boost LNG Plant Performance

The concept of Digital Twin is not new and it has been around for more than a decade. A digital twin is a complete 360-degree replica of a physical asset such as a heat exchanger, turbine, pump, compressor or entire plant that enables modelling of process and control, and monitoring of equipment health. It is the foundation to optimise LNG production and to detect equipment problems before failures occur, uncovering new opportunities for process improvement while reducing plant downtime. Only in recent years, the advancement in technology – cloud platform, analytics and computing power -and greater clarity on the use cases have accelerated the adoption of digital twins. LNG companies are starting to realize the benefits of Digital Twin that enables unprecedented real-time insights of their operations, elevating their operational excellence to the next level: A 0.1% increase in production due to improved process and operating efficiency can easily yield several millions of dollars in additional revenue.

This white paper discusses the approach to leverage data, simulation and analytics in Digital Twin Strategy to maximise LNG Production at lower cost:

  • Increase throughput and yield
  • Reduce energy consumption (MMBTU/ton)
  • Reduce unplanned downtime
  • Discover additional unattained potential uplift
  • Identify and resolve the bottlenecks preventing the extra uplift
