Our Services

System integration

LIWACOM provides a complete range of integration services for the SIMONE software package. Our system integration services cover turnkey integrated automation systems, support of our integration partners, and development of SIMONE-based customer applications.  

Our integration services cover e.g. the elaboration of the system's detailed specification, the development of the SIMONE model of the customer's transmission or distribution system, commissioning, acceptance testing, training, and warranty and maintenance services.


LIWACOM provides comprehensive simulation training that we precisely tailor to the specific needs of each customer. We conduct training courses at our customer's premises, at LIWACOM Essen, and we provide web based training.  

Our standard SIMONE training program covers the user interface, the handling of simulation scenarios, and SIMONE's advanced modelling features. We offer standard training sessions for online simulation users and administrators, as well as for SIMONE interface programmers.  

Workshops and individual training sessions complement our standard training program.  

We train control room engineers for the safe and efficient gas system operation. The trainees solve practical gas control tasks using the SIMONE Training Simulator. The software provides an offline simulation environment that realistically mimics the gas transport process, as if it were online. It allows realistically simulating scheduled tasks as well as emergencies.

Consulting and support

LIWACOM provides competent and efficient consulting support with regard to implementing SIMONE and simulation modeling.  

Our help-desk supports customers in promptly answering questions regarding the functionality, use and administration of SIMONE.

Software maintenance

The SIMONE package is continuously being upgraded and expanded. LIWACOM offers Software Maintenance that includes software upgrade and help-desk services. This Service package keeps you and your SIMONE software always up-to-date.    

Software Upgrade Service. It includes the access to new SIMONE releases and service packs.  

Help desk Service. It supports customers in promptly answering questions regarding the functionality, use and administration of SIMONE.

Network modeling

Our customers leverage the LIWACOM experience in adequate hydraulic modeling. We set up and maintain your SIMONE network model, accounting for the specifics of your transmission or distribution grid. We import the source data e.g. from GIS or your legacy system, and transform it into an accurate, robust, and highly performing SIMONE model.


Beside of Support / Maintenance / Training for the Software SIMONE, LIWACOM offers the following engineering, consulting and study services:

FEED, Basic- and Detail Design in Process, E/MSR-Techniques

Support for preparation of technical enquiries and specifications for gas transport and storage systems, especially

  • Pipeline systems,
  • Metering stations,
  • Compressor stations,
  • SCADA systems.

Preparation, Examination and Documentation of HAZOP / SIL Studies

  • Preparation, examination, and documentation of HAZID / HAZOP and SIL studies for gas transport/storage systems.
  • Follow up of the created action points.
  • Close out report.

Hydraulic Studies for Gas Transport Systems 

  • Capacity investigations.
  • Support for specification of technical enquiries for compressors (e.g. required power, head and volume flow for several operation points).
  • Transient pressurization / depressurization for commissioning/decommissioning scenarios.
  • Pre-design of depressurization systems.
  • Simulation of modifications in existing systems (capacity calculation, e.g. transient behavior of the network for several load profiles).
  • Calculation for scenarios with changes in gas quality / calorific values (e.g. new biogas or H2 injection).
  • Training for SIMONE users with individual tailor-made key aspects.
