SPG Steiner

What SPG Steiner does

SPG Steiner GmbH is a family-owned German EPCM (Engineering, Procurement, Construction, Management) contractor headquartered in Siegen, Germany, with a corporate lineage tracing back to a forge founded by Heinrich Steiner in 1701. The company specializes in modularized small- and midscale turnkey solutions for the energy, petrochemical, and chemical industries, organized around four core technology pillars delivered through wholly-owned subsidiaries: cryogenic and low-temperature storage tanks for liquefied gases (LNG, LPG, ammonia, ethylene, ethane) via adapt GmbH; modularized gas treatment packages via Gastec GmbH; smokeless flare systems and low-emission industrial burners via Prematechnik GmbH (in-house since 1956); and offshore structures including wind platforms and ice engineering via IOE IMPaC GmbH. Notable proprietary technologies include the PremaFlare® and PremaNOX® combustion brands, SOTLL sideways offshore LNG transfer system, and IMPaC's ice load prediction modeling. The company also operates small/midscale LNG terminals (20,000–160,000 m³) and modularized process plants as integrated offerings.

Revenue is generated through project-based EPCM contracts, custom equipment fabrication contracts, and turnkey delivery milestones, with project values typically ranging from tens of millions to over $100 million (e.g., the 53,000-tonne BASF Antwerp ammonia tank, 42,000 m³ Linde Portovaya LNG tank, 80,000-tonne Allied Green Ammonia storage deal, and 250,000 Nm³/h-capacity flare systems). The go-to-market is direct enterprise field sales to major energy, petrochemical, and chemical operators — a customer roster that includes Shell, BASF, Linde, Siemens, Nord Stream AG, OCP Group, Enagas, EON, Evonik, Thyssen Krupp, Allied Green Ammonia, and Fauji Fertilizer. The company maintains offices in Germany (Siegen, Frankfurt, Hamburg), Romania, Russia, UAE, China, Singapore, Libya, and most recently the Netherlands (December 2025), with active projects across Europe, the Middle East, Asia-Pacific, Africa, and the Americas. SPG Steiner is led by Managing Directors Philippe Steiner and Oliver Steiner and holds ISO 9001, ISO 14001, and SCC-P certifications audited by Lloyd's Register.
