What Griesemann does

Griesemann Gruppe GmbH & Co. KG is a family-owned German industrial engineering and plant construction company founded in 1976 in Wesseling, Germany, that delivers multidisciplinary plant lifecycle services to the process and energy industries. Its offering spans four pillars: Plant Engineering & Construction (turnkey EPC projects up to EUR 25M and EPCM up to EUR 100M TIC); Engineering Services (process, mechanical, piping, civil/steelwork and E/I&C engineering from concept through commissioning); Plant Systems (multidisciplinary fabrication, industrial installation and maintenance delivered via a 12,000+ m² Rhineland fabrication centre and 45+ locations); and Lightning Protection operated through the Blitzschutz Graff subsidiary.

The technology stack centers on integrated engineering databases combining 50+ leading-provider and self-developed tools, an integrated QHSE project management office, 3D laser scanning capabilities, and domain specialization in Power-to-X, hydrogen and LOHC technologies. The company maintains ISO 9001, SCCP and ISO 50001 certifications and operates a workforce of approximately 1,750 across Germany, Austria and the Netherlands.

Revenue is generated through project-based professional services contracts (EPCM/EPC) plus managed maintenance and framework agreements with enterprise clients in refinery, petrochemistry, chemistry, fine chemistry, biotechnology and pharmaceuticals, supplemented by specialty lightning protection services through Blitzschutz Graff. Customers are acquired via enterprise field sales targeting large industrial operators; notable disclosed clients include DLR (German Aerospace Center) for a Power-to-Liquid research facility and Bayernoil Raffinerie / Hydrogenious LOHC for the first industrial LOHC dehydrogenation plant in Bavaria. The company has no public listing, no external private equity exposure, and is controlled by the Griesemann family with Björn Griesemann as Geschäftsführer.
