ATMOS GSIM

ATMOSTM GSIM Offline: Model for Off-line Simulation

ATMOS(TM) GSIM Offline is a transient pipeline simulator for gas tronsmission pipelines and local distribution networks (City Gate).
ATMOS(TM) GSIM Offline can be used for the design and operational analysis of existing networks. ATMOS(TM) GSIM Offline calculates flow, pressure, temperature. line-pack, survival time under different operational scenarios. Initial states can be loaded from the live pipeline or historical data.
ATMOS(TM) GSIM is unique as it has been engineered in C# and VB. NET in-house by ATMOS engineers for a Windows & Web environment. Customer-specific equations of state and flow equations can be incorporated on request.

ATMOSTM GSIM Online:Hydraulic Model for On-line Simulation

ATMOS(TM) GSIM Online is a transient pipeline simulator for gas tronsmission pipelines  and can be used for the real-time operation of pipeline systems.

ATMOS(TM) GSIM Online has a Look-Ahead Module (LAM) that runs periodically in the background without Operator input. The LAM is an online application, displays future values of pressure, flow. temperature, survival time, gas velocity, total line-pack or line-pack along specific pipeline sections. The LAM module uses the online data to predict the effect of real operational changes at a point in time defined by the operator. The LAM is initiated automatically by operational changes, periodically initiated at an operator defined time interval or at any moment by the operator.
ATMOS(TM) GSIM Online is unique as it has been engineered in C# and VB. NET in-house by ATMOS engineers for a Windows & Web environment and contains the latest solvers.
