Essen, 7.10.2024 – Vienna, Austria, was the destination for the SIMONE Congress on Pipeline Simulation and Optimization 2024, hosted by LIWACOM Informationstechnik GmbH, Essen, in collaboration with SIMONE Research Group s.r.o., Prague. The event attracted more than 95 delegates from 21 countries and 38 companies.

This was the 16^th SIMONE Congress since its inception in 1991, which has been held every two years, with the exception of 2020 when the 15th congress in Sofia was postponed to 2022 due to the pandemic.

The opening keynote was delivered by Helmut Wernhart from Austrian Gas Grid Management (AGGM), based in Vienna, who provided a historical overview of the city and insights into the development of Austria's gas infrastructure.

The technical program focused around three key areas:

- Transformation of transmission networks (from natural gas to H2 or CO2 transmission)

- Training with SIMONE

- Simulation of classical SIMONE applications, such as quality tracking

These topics were presented by customers, who shared their experiences using SIMONE, offering both practical insights and a broader perspective. Additionally, the program included presentations on new features and future developments, such as the SIMONE Web Interface.

The social program continued the SIMONE Congress tradition of exploring local culture and history. Participants chose from five "Old Town Walks," which included visits to an iconic Viennese coffee house, architectural landmarks, hidden courtyards, and majestic sites such as the Hofburg. Other options included a horse-drawn carriage tour and a bus tour of the city.

The day concluded with a congress dinner at Fuhrgasslhuber, a traditional Viennese Heuriger, where attendees enjoyed a classic Austrian buffet of local cuisine. Thanks to the sunny weather, participants relaxed in the cozy courtyard late into the evening.

The organizers, LIWACOM Informationstechnik GmbH and SIMONE Research Group s.r.o., would like to express their heartfelt thanks and appreciation to all the speakers for their excellent presentations.

Groningen, The Netherlands, October 2018. On October 18th the “Go Live” of the Jason project for the new control center was celebrated with the Grand Opening Ceremony at Gasunie headquarter in Groningen. In front of all Gasunie employees a great display showing the gas transport key data was unveiled in the entrance hall in the presence of Han Fennema, the CEO and chairman of the Executive Board, and Bart Jan Hoevers, member of the Executive Board and Director Gasunie Transport Services (GTS). The name of the system from now on is GENIUS.

The pipeline network will be operated by the SCADA system AGMS from Schneider Electric Serbia and the fully integrated simulation package SIMONE. In an image movie the interaction between the AGMS and SIMONE was demonstrated and the functionality was very well appreciated by Gasunie. The movie also highlighted the importance of the daily operation in the control room.
