ATB Riva Calzoni operates in the energy industry and is divided into hydrocarbons and renewable power sectors.
ATB Riva Calzoni oil and gas division offers a wide range of services for the hydrocarbons sector. The company supplies process packages for engineering, services for engineering, procurement and construction (EPC), pressure vessels, evolved packet systems (EPS) and operation and maintenance (O&M) services.
Hydrocarbons engineering and design services
Through its controlled company DG Impianti, ATB Riva Calzoni's engineering and design business unit delivers a comprehensive range of services, from commissioning and start-up assistance to conceptual and feasibility studies.
As a front-end engineering and design (FEED) provider, ATB employs a multidisciplinary approach, using its value engineering capabilities and project experience.
The company uses state-of-the-art technologies and the latest methodologies to create solutions for clients in the hydrocarbons industry.
ATB Riva Calzoni provides optimised project development solutions through evaluation and screening of relevant products and technologies.
ATB employs a typical front-end gate process that works with the client to analyse different solutions for various field development scenarios.
Engineering, procurement and construction packages for oil and gas projects
ATB Riva Calzoni's engineering, procurement and construction (EPC) division offers clients competencies such as procurement, project execution, fabrication, installation and commissioning services.
Main contracting of mission-critical solutions for the upstream / downstream oil and gas and power plants is also available.
The company's key competencies in EPC packages for hydrocarbon projects include:
- Turnkey deliveries of oil and gas production, and processing installations
- Project engineering, procurement services, and fabrication and start-up services
- In-house expertise of fabrication and completion services

- Maximum thickness: HCK reactor with thickness of 358mm
- Maximum weight: HDT reactor with weight of 1,400t
- Maximum length: C2C3 splitter column with length of 100m
The company has manufacturing facilities in Italy and Malaysia, through its controlled company MMHE ATB JV. Both have direct access to the sea in Pasir Gudang, Malaysia and Porto Marghera, Italy.
About ATB Riva Calzoni
ATB Riva Calzoni was established in 2003 by combining Acciaieria e Tubificio di Brescia (ATB) and Riva Calzoni Impianti (Riva Calzoni).
The company has increased to meet the rising demand for components within the oil and petrochemical industries, as well as thermoelectric and hydroelectric power plants.
Both companies have operated for more than 100 years in the design, manufacturing and installation of mechanical equipment for a range of industrial applications.
