ATMOS International Introduces ATMOS GSIM in North America

ATMOS International (ATMOSi), a leading provider of pipeline application software solutions worldwide, introduced North American users to the latest version of its gas pipeline simulator, ATMOS GSIM, at the October 2007 meeting in Calgary, Canada of the Pipeline Simulation Interest Group (PSIG).  The occasion was a ground-breaking "Technology Showcase" session where the PSIG Board challenged vendors to demonstrate their product capabilities in the context of two very specific and hydraulically complex gas pipeline simulation scenarios.

ATMOS GSIM, the most modern simulation tool available for gas transmission and distribution network simulation, was the only product that successfully provided a live demonstration of both scenarios, and ATMOSi was the only company to solve the problems live without having to modify any of the scenarios to reduce the complexity of the challenges set by PSIG.

Users, and surprisingly vendors also, were most impressed by the performance of ATMOS GSIM.

Under development for the last four years by a technical team consisting of Dr. Jason Modisette, Dr. David Basnett, Paul Cleghorn, and Einac van Meurs (formerly of the Dutch Gasunie), ATMOS GSIM has many very powerful and unique features to help planning and operational users alike:

·         Transmission and distribution, steady-state and transient simulation in a single solution;

·         Built to use modern interface standards such as OPC and SQL;

·         Offline and online simulation using the same model configuration;

·         Adaptive grid length to maximize both simulation accuracy and speed; and

·         A fundamentally new method of real-time simulation called Maximum Likelihood State Estimation.

ATMOS GSIM is deployed as the simulation engine in pipeline operator training simulation systems, and is also used in ATMOS GMS, a business-rule-oriented system for nominations, allocation, proration and imbalance accounting.  It is (being) deployed on several major gas transmission networks around the world.
