Core offering

Priner delivers integrated industrial engineering and infrastructure services through 12 grouped companies, offering 75+ specialized services for large industrial clients in oil and gas, mining, paper and cellulose, steelmaking, and energy. Its offering spans industrial services (access, painting, insulation, boilermaking), integrity and inspection engineering (non-destructive testing, materials labs, welding engineering, subsea solutions), infrastructure (geotechnics, structural rehabilitation, trenchless pipe repair, suspended scaffolding platforms), and industrial assembly (electromechanical, piping, fire/lightning protection). The firm also develops proprietary inspection software platforms (SPI, SafeCrack, RBI/IBR) and runs the UNINSP accredited training center.

Product overview

Priner offers integrated and comprehensive solutions in industrial engineering and infrastructure for sectors including oil and gas, pulp and paper, mining, steel, and energy. The company's portfolio is organized into four main service categories: Industrial Services (access solutions, industrial painting, thermal insulation, pressurized habitats, civil maintenance, and boilermaking), Engineering of Integrity and Inspection (non-destructive testing, advanced engineering, materials engineering/laboratories, equipment inspection, welding engineering, training, inspection software, and subsea solutions), Infrastructure (geotechnical solutions, structural rehabilitation, Priner Pipe Repair trenchless rehabilitation, and PrinerDeck suspended scaffolding platform), and Industrial Assembly (electromechanical assembly, machinery assembly/disassembly, piping systems, fire/lightning protection, and conveyor/structure installation). The proprietary SPI (Priner Integrity and Inspection System) serves as the core platform for inspection data management, complemented by specialized software tools including SafeCrack for fracture mechanics analysis, RBI Software for risk-based inspection, and various NDT solutions including contactless magnetometric inspection (MMM) for subsea applications. The UNINSP training center provides professional certification programs accredited by Abendi.
