SIMONE off-line steady-state and transient simulation serves system planning and capacity determination.
AIR LIQUIDE Deutschland
AIR LIQUIDE Deutschland operates long-haul high pressure gas pipeline systems in Germany’s Rhine-Ruhr industrial area that transport oxygen and other technical gases to steel producers, and the chemical and petrochemical industries. Regulations in Germany require the transport pipelines to be equipped with facilities that allow to detect and to locate a pipeline leak during steady, dynamic, and interrupted fluid flow. The customer uses SIMONE Leak Detection and Location for its oxygen and nitrogen pipeline networks. AIR LIQUIDE has conducted blow-out tests under the auspices of the Technical Supervisory Association to verify the proper operation of the LIWACOM software.
Energinet.dk owns and operates and the high pressure gas transmission network in Denmark. SIMONE real-time simulation supports the customer in operating the gas pipeline system. The simulator provides the properties of the various gas supplies, mainly the calorific value, throughout the transmission network. SIMONE tracks the travel of Pipeline Inspection Gauges (PIG) through the pipes. The back-office of Energinet.dk uses SIMONE for short-term flow studies and system expansion planning.
China National Offshore Oil Corporation ("CNOOC"), the largest offshore oil & gas producer in China, has acquired SIMONE for carrying out pipeline simulation studies. The sales has been concluded upon CNOOC’s diligent tests of our standard product.
The contracted SIMONE package models pipeline flows, pressures and temperatures. It tracks the compositions and parameters of the supplied fluids, as they move and merge in the transmission and distribution networks. The software provides high fidelity and detail in modeling compressor stations that push the flows through the pipelines.
FGSZ Natural Gas Transmission Company
FGSZ Natural Gas Transmission Company owns and operates the Hungarian high-pressure gas transport grid comprising about 5800 km transmission pipelines, 6 compressor stations and around 400 delivery points.The FGSZ gas control center located in Siófok uses a SIMONE online simulation system to assess the actual system state, simulate look ahead states, and analyze what-if scenarios. In addition, SIMONE installation acts as process simulator for an operator training simulator, supplying substitute “measurements” in reaction to simulated scenarios and operator interventions.
Fluxys Belgium is the operator of the infrastructure for gas transmission, gas storage, and the receipt terminal of liquefied natural gas (LNG) in Belgium. The company has developed its infrastructure into a crossroads of international gas flows for North -West Europe. Fluxys Belgium is an affiliate of Fluxys, a Belgium-based, fully independent gas infrastructure group with assets throughout Europe. Our customer uses the SIMONE package since 1992 for various gas flow simulations, such as preparing the ten years investment plan, or verifying if the given infrastructure can actually handle the booked capacities. At the 12th International SIMONE Congress 2014 in Cascais/Portugal Fluxys presented a paper that describes the calculation of maximum available capacity at interconnection points of the Belgian natural gas network with SIMONE and the in-house developed CASSIS (Capacity Simulation System) application.
Gascade is an Independent Transmission Operator of one of the largest natural gas infrastructures in Germany that links five European countries. Our customer uses the SIMONE simulation package for operations scheduling, and transport and capacity planning.
Gasum is a diverse service provider for energy producers, homes and industries in Finland. The company owns and maintains the Finnish natural gas transmission network. Gasum, including its predecessor company, have been using SIMONE software for system planning purposes long ago since 1991. Recently LIWACOM has implemented SIMONE Real-time Simulation, including Leak Detection and Gas Quality Tracking, in Gasum’s new SCADA system to support its gas control engineers.
Gaznat supplies and transports high pressure natural gas to Western Switzerland. Liwacom has supplied SIMONE real-time simulation as part of the company’s new SCADA system. The SIMONE software includes the tracking of calorifc values and other gas quality parameters.
Plinovodi d.o.o. is the transmission system operator for natural gas in Slovenia. The company owns and operates the national transmission network. Our customer uses SIMONE for real-time support in its gas control center, and for off-line business applications, such as evaluating of transmission capacities, expansion planning, and maintenance scheduling.
REN Gasodutos operates the national natural gas transmission system in Portugal. SIMONE software provides real-time simulation support to the REN Gasodutos control room dispatchers, in order to ensure the secure and efficient supervision and control of the pipeline network.
