About the Griesemann Group
For over 50 years, the Griesemann Group has been a partner to the process and energy industries, covering the entire life cycle of industrial plants: from concept studies and multidisciplinary basic and detail engineering through to turnkey projects, fabrication, installation and maintenance. With 1,750 employees across all relevant trades – including 850 skilled workers in industrial installation – the company realizes new plants, modernizations and maintenance services at refineries, petrochemical and chemical sites as well as in the field of green technology such as electrolysis, hydrogen and power-to-X plants. Its own plant engineering facility fabricates steel, tank and skid structures at a 12,000 m² multi-trade fabrication site, using primarily steel as material. A reference project is the EPC contract from DLR for the world's largest research facility for power-to-liquid fuels (2,500 t/year) in Leuna. Further divisions are lightning protection (over 160 years of experience, 150 employees), E&I technology, piping construction and work at height.
