Services
Antranova helps organisations understand, troubleshoot and improve complex technical systems when the underlying causes are not obvious. The work combines technical experience, system analysis, calculations and simulations to create clear decision support.
When documentation, operating data or previous actions do not explain a problem, a focused investigation is often needed. Technical mapping is a concrete first step to understand causes, assess risks and recommend the next action.
- Technical troubleshooting and root-cause analysis
- Independent technical review
- Technical system mapping
- Consequence analysis before modification
- Calculation, modelling and simulation
- Verification and technical review
- Training and technical documentation
Clearly defined first step
An initial assignment is tailored to the specific technical question and may, for example, consist of a technical review, targeted troubleshooting, an independent review or a smaller analysis. Scope, deliverables and price are agreed once the problem and the available information have been defined.
Investigation of hard-to-explain operational problems
A focused technical investigation to understand why a system does not perform as intended and which factors most likely affect the outcome.
A technical diagnosis can be a clearly defined first paid step, but the setup is tailored to the specific problem and does not limit what a continued assignment may cover.
The aim is to understand the problem, identify likely causes and propose next steps without starting a large project.
Deliverable: a short report with clear problem areas, likely causes and recommended next steps.
The assignment can be limited to a short review or developed into a more detailed analysis.
- Review of documentation and system descriptions
- Identification of critical dependencies and failure mechanisms
- Assessment of operating problems or planned changes
- Simplified calculations or models where needed
- Recommended next steps for action or verification
Independent technical review
When a supplier has proposed a component replacement, a modification, or delivered a calculation or simulation model validated by the supplier itself, the organisation often needs an assessment from someone with no stake in the outcome. The review can cover calculation basis, simulation and process models, test plans and proposed actions. The client receives a traceable statement of what the material supports, what it does not support, and what additional work is needed before a decision.
Professional background in independent review
The examples below refer to previous experience. Assignments in nuclear power and power generation are not currently offered.
- Validation and verification of a calculation code for the dispersion of radioactive substances, through systematic comparison against an established reference code. Client: regulatory authority.
- Verification of thermal-hydraulic calculation models against experimental measurement data from international test facilities. Client: regulatory authority.
- Independent review and assessment of proposed changes to safety-related documentation at a nuclear facility. Client: facility owner.
Technical investigations and system analysis
When operational disturbances, deviations or performance problems keep recurring, the real system behaviour must be investigated rather than inferred from assumptions alone. Inspection, measurement and reconstruction are used to understand what is actually happening.
Analysis of the interaction between flow, pressure, heat, mechanics, electrical systems, automation, control and dynamics
An in-depth analysis of how components, subsystems, operating conditions, electrical systems and control strategies affect the system's overall performance.
Thermohydraulic process analysis
Analysis of cooling systems, heat systems, pumps, valves and pipework. Pressure drop, flow distribution, transient processes, operational cases and disturbances.
Technical decision support for corrective actions and investments
An independent assessment of problems, alternatives, consequences and technical risks before the customer carries out a change or an investment.
Technical training and communication
Knowledge transfer via simplified models, simulators and documentation adapted to the recipient. Raises internal competence and reduces dependence on external support.
Identification and assessment of improvement opportunities
Analysis of possible improvements in capacity, stability, energy use, control, availability or maintenance.
Methods and tools
Depending on the nature of the problem, Antranova uses technical calculations, simplified models, dynamic simulations, data analysis and experience-based system analysis. The tools are selected according to the question that needs to be answered.
Examples of problem areas
- Unstable flow and pump operation
- Pressure oscillations and rapid transients
- Temperature problems and heat transfer
- Control and regulation problems in technical systems
- Consequences of modification or component replacement
- Technical dependencies between subsystems
- Systems lacking updated or correct documentation
- Need for independent technical review
Model fidelity – the right level for the right question
Not all analysis needs to be complex. The same question can be developed step-by-step from a simple web model to advanced thermohydraulic analysis without losing structure or comparability.

Interpretation
Most technical questions should begin at level 1 or 2 to quickly establish reasonable assumptions, bound the problem and identify which parts truly justify higher model fidelity. Escalation to level 4 or 5 should be driven by decision consequence, training realism, technical risk or verification needs.
AntraSIM contains simulators that demonstrate level 1 in practice. Open AntraSIM →

Technical domains
System types
- Pump systems and flow systems
- Cooling systems and heat transfer
- Piping systems and HVAC-related installations
- Industrial process systems
- Systems with dynamic and coupled dependencies
Assignment types
- Troubleshooting and root-cause analysis
- Capacity and performance analysis
- Consequence assessment for changes
- Support for procurement or investment decisions
- Training and competence development
Industries and application areas
The approach is applicable in operations where several technical subsystems interact and where operational problems, capacity constraints or investment decisions require a holistic assessment.
Assignments in nuclear power and power generation are not currently offered. Previous experience in these fields is presented as professional background.
The industry itself is not the central point. What matters is that the operation is built on complex technical systems where the interaction between flow, pressure, heat, mechanics, electrical systems, automation, control and dynamics affects the outcome.
When does this fit?
- When a system behaves unexpectedly and the underlying cause is unclear
- When existing documentation is incomplete or outdated
- When changes require consequence assessment and robustness analysis
- When decisions require clear assumptions and traceable evidence
- When the organisation needs to improve its technical understanding of a system
For consulting and engineering firms
Partner and subconsultant support
Antranova can support a concrete project as a subconsultant or specialist resource when there is a clearly defined capacity or competence need in system analysis, modelling, independent review or verification.
The assignment is defined through clear deliverables, interfaces and responsibilities. Visibility, client contact, confidentiality and the commercial model are agreed for each individual assignment.
Start an assignment
Briefly describe the system and the problem – and what type of deliverable is needed. Response with a proposed approach normally within 1–2 business days.
