What IREM does
IREM S.p.A. is a privately held Italian industrial construction contractor headquartered in Siracusa, Sicily. Founded in 1979, the company delivers mechanical construction, piping fabrication, tank construction, and industrial maintenance services primarily to the Oil & Gas, Power, and Chemical sectors. IREM operates through an integrated group of subsidiaries — including ICOS, Solesi, SONIM, TECHIMP, Irtis, and Res Integra — and executes projects across more than 20 countries on four continents, supported by the Punta Cugno fabrication yard covering 180,000 square meters.
The company's revenue model is project-based EPC contracting, with execution driven by large multi-year mega-projects for blue-chip energy and process industry clients such as ExxonMobil, ENI, ThyssenKrupp, KNPC, EDF, Borealis, TOTAL, and PREEM. Capacity is anchored by approximately 4,000 employees delivering 5–14 million man-hours per year, with single-project scope reaching up to 8.6 million man-hours (e.g., the MOL/ThyssenKrupp Polyol project). IREM holds an extensive certification portfolio — ISO 9001, ISO 14001, ISO 45001, SA8000, VCA Petrochemical, ASME Stamp U&S, ISO 3834, and EN 1090 — that qualifies it to bid on regulated industrial capex globally. Recent strategic initiatives include the H2-SR green hydrogen project (2023), the DRI green steel project with ThyssenKrupp/SMS (2026), and the IREM Academy workforce development program.
IREM is led by CEO Giovanni Musso, Chairman Mario Saraceno, and Co-CEO Simone Bittoni. In January 2024 the company raised $5.4 million in growth financing from Azimut Direct, and has received CRIBIS Prime Company recognition (2022, 2023) and AGCM legal rating (2025). The company is positioned at the intersection of traditional hydrocarbon EPC and emerging low-carbon industrial infrastructure, with forward-looking exposure to green hydrogen and green steel value chains.
