Plant Systems & Services

What Plant Systems & Services does

Plant Systems & Services PSS GmbH is a privately-held German industrial services holding founded in 1977 by Ludger Kramer and headquartered in Bochum. The group is structured around two core operating subsidiaries — ETABO Energietechnik und Anlagenservice GmbH and Veltec GmbH & Co KG — that deliver engineering, construction, maintenance, repair, modernization, and nuclear decommissioning services to the energy and process industries. Its service portfolio spans pipeline construction, heat exchangers and pressure vessels, turbine service, boiler and combustion systems, tank construction and tank farm piping, valve and damper technology, and air/gas preheaters. The group operates from strategic locations in Germany (Bochum, Karlsruhe, Zörbig), Switzerland (Hunzenschwil), and Scandinavia (Sweden) via wholly-owned entities, with a dedicated manufacturing facility in Zörbig producing components for the subsidiaries.

The company's technology stack is anchored by industry-standard engineering and project management software — PDMS/E3D for collision-free plant planning, NavisWorks for visualization, Primavera and MS-Project for scheduling, Rohr2 for pipe analysis, Sinetz for flow distribution, and PED 6.0 for pressure equipment directive compliance — with no disclosed AI/ML layer. Its go-to-market is direct enterprise field sales targeting large industrial operators in refineries, chemical plants, conventional and waste-to-energy power generation, tank farms, pulp and paper mills, and metal processing. Revenue is generated primarily through professional services (engineering, maintenance, repair, modernization, and EPC contracts) on a custom-quoted, project-scope basis with no publicly disclosed pricing.

In FY2023, PSS reported consolidated revenue of EUR 206.2 million, with the revenue mix split across Veltec Scandinavia (EUR 83.4M, ~40%), Etabo Gruppe (EUR 85.2M, ~41%), and Veltec Deutschland (EUR 41.7M, ~19%). The group maintains EUR 15.7M in equity capital, EUR 21.5M in own liquidity, and a EUR 44.5M guarantee (Aval) framework, indicating a self-financed, founder-controlled capital structure. Primary customer verticals are refineries, tank farms, and energy utilities/waste recovery, with secondary exposure to chemicals, paper and pulp, and metal production. The customer base is described as European industrial enterprises served through long-embedded relationships, with no named customer logos disclosed in the available data.

Direct peers

• Bilfinger: German-headquartered industrial services group providing engineering, maintenance, and plant services to energy, process, and chemical customers across Europe. Closest direct competitor to PSS Gruppe with overlapping end markets in refineries, power plants, and tank farms, though at significantly larger scale.
• IKM Gruppen: Norwegian industrial services provider specializing in maintenance, modification, and engineering for offshore and onshore energy customers. Closely comparable to PSS's Veltec Scandinavia operations in terms of customer base (energy/process industries) and service mix (maintenance, repair, modification).
• Babcock Borsig Service: German industrial services firm specializing in boiler, turbine, and power plant maintenance — directly overlapping with PSS's Kessel and Turbinenservice product lines and serving the same conventional power and waste-to-energy customer base.
• WISAG: Large German facility and industrial services group offering technical services, maintenance, and energy management to industrial customers. Comparable to PSS in geographic footprint, customer segments, and broad industrial services portfolio.
• InfraServ Wiesbaden: German industrial site operator and service provider serving chemical and process industry customers with maintenance, engineering, and facility services. Comparable to PSS in serving process industry customers with integrated maintenance and engineering offerings.
• Karl Meyer Gruppe: German industrial services and environmental technology firm specializing in tank construction, tank cleaning, and piping services. Directly comparable to PSS's Tankbau, Tanklagerverrohrung, and maintenance capabilities.

Broad incumbents

• Jacobs Solutions: Global engineering and professional services firm serving energy, process, and infrastructure clients. While at much larger scale and broader portfolio, Jacobs competes for the same large EPC and maintenance frameworks that PSS addresses in Europe.
• Worley: Global energy and resources project services company providing engineering, procurement, and construction management for refineries, petrochemical plants, and power facilities. Comparable to PSS in core customer base and EPC service profile, but with global scale and primary focus on energy transition projects.
• Fluor Corporation: Global EPC firm serving energy, mining, and industrial clients with engineering, procurement, fabrication, and maintenance services. Overlaps with PSS in refinery, petrochemical, and power plant services at the project-scale, though at materially larger scale.
• Stork (a Fluor company): Dutch-based industrial services and asset integrity provider serving oil & gas, chemical, and power customers across Europe and globally. Direct overlap with PSS's maintenance, modification, and integrity services in the European process and energy sector.
