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.

Sofia, Bulgaria, April 2022.The 15th International SIMONE Congress on Pipeline Simulation and Optimization finally took place April 27-29, 2022. Due to Corona, the long-awaited event had to be postponed for two years.

SIMONE users and interested experts from all over the world met in Sofia to share their experiences.

 The presented papers dealt with topics on the practical use of SIMONE and descriptions of SIMONE integration projects.

Last but not least, “Going Green” was a big theme – several presentations dealt with the forward-looking theme of the future: using the gas infrastructure for hydrogen, coupling of gas and electricity networks for optimizing future demand and analyzing characteristic values for alternative fuels injection.

The communicative atmosphere of the SIMONE Congress is traditionally enhanced by a social event. The evening program was a gala dinner that took place at the National Museum of History, which was the ideal place to enhance the communicative atmosphere of the congress.

Am 9. Dezember 2021 wurde eine neue kritische Sicherheitslücke bekannt, die mehrere Versionen der beliebten Apache Log4j 2 Logging-Bibliothek betrifft. Wenn sie ausgenutzt wird, kann sie zu Remote Code Execution (RCE) führen, indem eine bestimmte Zeichenfolge auf den betroffenen Installationen aufgezeichnet wird.  

Die SIMONE Software ist von der Log4Shell Sicherheitslücke nicht betroffen!
SIMONE installiert oder verwendet die betroffene Java Library nicht. SIMONE verwendet seinen eigenen, nativen Logging-Mechanismus.

The congress was the 14^th congress in a row since 1991 and LIWACOM’s 30^th birthday.

The opening speech with a journey back into the past was held by the founding father G. Wagner and supported by J. Kralik.

The main focus of the technical program was on engineering, simulation and dispatching/operations as presented by our customers showing their experience with SIMONE but also providing the ability to take the broader view.

The program was rounded up by giving an outline to new features and development directions.

The social program followed the tradition of the SIMONE congresses to visit places of historical, natural or human interest. The choice was between City Tour, Prado Tour and the Bernabeu Stadium which was followed by the congress dinner held in Casa Patas, a traditional tavern restaurant. After dinner a fascinating flamenco show brought us into the right mood to celebrate the 30^th birthday with a marvelous cake and cava.
