Xodus delivers gas modelling for Australia Pacific LNG

Published by
LNG Industry,

Xodus Group has announced the delivery of a new Integrated Production Modelling simulation suite for Origin to run complex scheduling scenarios for the Australia Pacific LNG project.

Simulation experts in Xodus’ Perth operation conducted detailed modelling of both the compression facilities and the high pressure pipeline network. The work provides Origin with the power to run detailed and fully automated operating scenarios through an intuitive user interface to accurately simulate the gas delivery network to maximise operating efficiency and manage delivery risks.

The team used AspenTech’s HYSYS steady-state linked with Microsoft Excel software to simulate several aspects of the project demonstrating novel and world leading simulation capabilities. A further scope of work comprised the use of HYSYS dynamics to produce a hi-fidelity mimic of Origin’s centrifugal compressor control system to fully verify its design prior to installation. The value of both contracts was approximately AUS$300 000.

Andy Jones, General Manager of Xodus in Australia, commented: “Xodus has a long history of building digital oilfield solutions for global clients; however the Australia Pacific LNG project required a forensic, in-depth knowledge of the inner workings of the simulation software in order to produce a bespoke solution. We used specialist programming techniques to achieve a complex model unlike anything that has been produced before. It allows Origin to run very detailed operating case scenarios to optimize operating conditions, balancing project critical factors such as power usage versus line pack availability.”
