What Tenenge does
Tenenge is a Brazilian industrial engineering, procurement, and construction (EPC) company founded in the 1950s and operating as a wholly-owned subsidiary of OEC (Odebrecht Engenharia & Construção), itself the engineering and construction arm of the Novonor Group. The company delivers integrated EPC services spanning project management, procurement, civil construction, electromechanical assembly, commissioning, start-up, assisted operations, technical assistance, and maintenance, organized across five core verticals: maintenance and industrial shutdowns; refineries and processing plants; chemical and petrochemical plants; thermoelectric and renewable energy plants; and pipelines and terminals. Notable execution capabilities include naphtha hydrotreating units using UOP-licensed technology (RNEST U-34), combined-cycle thermoelectric modernization (Santa Cruz, 350 MW to 500 MW), green ethylene plant expansion (Braskem, +30%), the Terminal Gas Sul LNG terminal (largest HDD maritime operation in South America), and the Etileno XXI petrochemical complex in Mexico. ISO 9001/14001/45001/37001 certifications and ENR Global Best Projects awards (including 2020 Best Global Project for Colon Urban Renovation in Panama) reinforce compliance and execution credibility.
The company serves primarily enterprise and state-owned clients in oil and gas, petrochemical, energy, and infrastructure sectors, with Petrobras, Braskem, New Fortress Energy, and Lhg Mining as anchor customers. Revenue is generated through long-duration EPC contracts awarded via competitive bidding, supplemented by industrial maintenance services across Brazilian petrochemical poles (BA/AL/SP/RJ/RS) and consortium structures (e.g., Consórcio TEM Boaventura with EGTC Infra and Mota-Engil, Consórcio Enseada-Tenenge for barge construction). Operating geographies span Brazil, Mexico, Dominican Republic, Panama, Peru, Angola, Mozambique, and the United States, reflecting both domestic Petrobras-cycle exposure and selective Latin American/African project execution. Go-to-market is exclusively direct enterprise sales through tender processes; there are no retail, channel, or self-service distribution channels. As a subsidiary of OEC, Tenenge shares branding, management systems, and capital resources with its parent group, which reported R$5.2 billion in 2024 revenue (+48% YoY) and ranked #1 in the Brazilian Engineering Ranking 2025.
