What C3 Engenharia & Soluções does

C3 Engenharia & Soluções is a privately held Brazilian industrial engineering and services company headquartered in Lauro de Freitas, Bahia, and operating across 10+ Brazilian states from Amazonas to Rio Grande do Sul. Founded in 2005 and led by President Leonardo Castro and Vice-President Vinicius Castro, the company specializes in industrial maintenance, construction, assembly, and inspection services for petroleum refineries and petrochemical plants — primarily Petrobras subsidiaries, with named operations at RPBC, REPLAN, RECAP, REVAP, REGAP, REDUC, REPAR, REFAP, plus work for TRANSPETRO, UTE-CBT, and CARGO ENERGY.

The company's service portfolio is anchored by five core offerings: maintenance shutdowns (paradas de manutenção), routine maintenance, construction and assembly of industrial plants, industrial inspections (including non-destructive testing and 360° live video inspection), and industrial rope access. To differentiate field execution, C3 has built out a portfolio of proprietary or exclusive equipment including the SpiderJet robotic hydrojet system, Blastrac 500E abrasive blaster, the Qlayers 10Q robotic painting system (first deployed in Latin America by C3), the Cerberus tube bundle cleaning system, Xingtera smart helmets for real-time safety monitoring, industrial drones for thermography and inspection, IRIS eddy-current and laser non-destructive testing, and 3D mapping for pre-job visualization. The company is certified to ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and ISO 27001:2022, and is LGPD-compliant.

C3 operates a professional services revenue model under multi-year contracts and a formal bidding/licitation process. Services are priced per project with deliverables tied to scope, equipment type, and contract duration; pricing is not publicly disclosed. The company has completed more than 85 projects nationwide, markets through its corporate website (available in Portuguese, English, and Spanish), maintains an active social media presence, and runs the internal C3 Educa training platform plus a Trainee Program and PDL leadership development program in partnership with Instituto Planos. Customer concentration on Petrobras is extreme — every disclosed major customer is either Petrobras or a Petrobras-owned entity — and no external investors, private equity sponsors, or institutional funding rounds appear in the available material.
