Our Team
Engineers: Technical solutions for a reliable energy supply
The art of engineering and innovation have been our cornerstones from the very beginning. Our engineers plan highly complex technical projects and turn them into reality. Through their commitment, our engineering teams ensure that our clients continue to operate a reliable gas supply in the fields of energy storage and energy systems. Due to the energy transition, other exciting fields of activity are also developing in which our engineers plan and implement electrical systems or electrolysers.
Geologists: We don't stay on the surface
Large quantities of different energy sources are stored in various geological structures. The design, production, operation of storage caverns and the disposal in them are complex tasks that require engineering and geological expertise. The same applies to storage in reservoirs, such as depleted hydrocarbon deposits or aquifers.
IT: From analogue to digital
What was written on paper years ago is now digital. In recent years, an increasingly collaborative working environment has developed rapidly. We use these modern software and hardware solutions for our further development. Based on the knowledge of our engineers and scientists, our IT specialists develop innovative software solutions for our customers. Our customer projects, the working world’s dynamics and our collaboration ensure an exciting, future-oriented field of activity.
Project managers: At the heart of a highly complex energy world
Our services turn technical planning and engineering into reality. Our project managers skilfully link our customers with our in-depth technical expertise. Always with the aim of exceeding the desired project goals despite the high level of complexity. Should unexpected events occur, our project managers ensure smooth processes.
Commercial clerks: Nothing works without them
Our business administrators love to get the figures in the right order. Transparent project calculations, legal and contractual aspects as well as a demand-oriented purchasing of services ensure an optimum workflow of our projects. Closely interlinked with our technical developments, this results in a demanding and dynamic environment.
