Seven lines, one technical responsibility
Engineering offices stop at the drawing. Suppliers start at the purchase order. ARINA covers the span between them, so the interfaces stay ours instead of yours.
What we deliver
Plant engineering
Full multidisciplinary engineering for steelmaking and metallurgical facilities, greenfield or brownfield.
See the detail- Process & balance of plant
- Electrical & I&C
- Civil & structural
- Plant integration & FEED
Machine design & simulation
Equipment engineered from first principles and validated numerically before anything is cut.
See the detail- Equipment design
- FEA & stress analysis
- CFD analysis
- 3D modelling
Industrial digitalization
Simulation and plant data put to work: first integrate, then simulate, then optimize.
See the detail- Digital twin
- Logistics simulation
- SCADA & HMI
- Plant simulation
Fabrication
Heavy equipment built to our own drawings, pre-assembled and tested before it ships.
See the detail- EAF parts & water-cooled elements
- Ladles, tundishes & scrap buckets
- Aluminium equipment: furnaces, dryers, skimmers
- Steel structures
PMO & execution
The people who keep a project on its baseline once it leaves the drawing board.
See the detail- Project management
- Owner's engineering
- Site supervision
- Commissioning support
Capital spares
Critical parts for operating plants, including items whose original drawings are long gone.
See the detail- EAF spares
- LF spares
- CCM spares
- Fume extraction & material handling
- Refractories
- Scrap yard
Automation supply
Control and process intelligence across all three levels of the plant automation stack.
See the detail- Level 1: PLC, HMI and SCADA for EAF, LF and CCM
- Level 2: heat tracking and energy models that cut power-off time and electrode wear
- Level 3: MES and production management
- Predictive maintenance: transformer diagnostics and harmonic analysis
Close the scope before you commit the CAPEX
FEED is not a preliminary step. It closes the technical scope, sets a realistic CAPEX and protects margin during execution, all before any site intervention and before any RFQ goes out.
FEED removes the grey zones in supply boundaries while they are still cheap to remove.
POSCO Australia: greenfield steel plant concept. HKM Germany: full feasibility study of a new melt shop. Salzgitter: feasibility and basic design with CAPEX estimation. Hyundai Steel USA: FEED with complete plant simulation.
Concept to commissioning, and after
Any combination of the service lines can be taken on its own. Taken together, they follow the same seven phases.
- 01
Concept & feasibility
Techno-economic studies, mass and energy balance, site layout options.
- 02
Basic engineering / FEED
Process design, equipment specifications, civil criteria and a ±20% cost estimate.
- 03
Detail engineering
Construction drawings, instrument lists, cable schedules, MTO and vendor specifications.
- 04
Procurement & supply
Equipment design, manufacturing, factory acceptance testing and logistics.
- 05
Erection supervision
Field guidance, quality surveillance and multi-discipline interface coordination.
- 06
Commissioning & start-up
Cold and hot commissioning, performance tests and operator training.
- 07
Optimization & support
Energy audits, process optimization, remote diagnostics and plant upgrades.
