Plant and Systems Technology for Industry and Infrastructure

We build trust in the quality, functionality and availability of technical plants and systems.

Technical installations and systems must operate safely, in compliance with applicable requirements, and economically.
TÜV NORD supports the entire lifecycle – from planning and assessment through commissioning and operation to modernisation and decommissioning. With independent inspections and assessments, we support industry, energy supply and critical infrastructure.

Independent assessments for complex plants and systems

Technical installations are facing increasingly demanding requirements. Operators, planners, contractors and investors must ensure safety, quality, availability, energy efficiency and cost-effectiveness in equal measure. At the same time, the energy transition, digitalisation, the expansion of critical infrastructure, and new technologies such as hydrogen are increasing the complexity of planning, construction and operation.

TÜV NORD provides support through independent testing, assessments and expert evaluations. We analyse technical concepts, design documentation, verification documents and other relevant documentation with regard to plausibility, traceability and technical robustness. Our focus is on project-specific issues and the individual requirements of our customers. In this way, we provide a reliable basis for well-founded decisions throughout the entire plant life cycle – from planning and design through commissioning and operation to modernisation and decommissioning.

TÜV NORD EnSys combines many years of expertise in plant engineering, cooling, air-conditioning and ventilation technology, stationary large engines, emergency power supply systems and hydrogen infrastructure with independent, requirements-based and customised assessments. Our fields of application range from industrial and process plants to energy supply systems, data centres and other process engineering facilities.

For more detailed information on safety-related topics, please also refer to our Plant Safety section.

More than regulatory compliance

However, the intended operation of a plant often involves additional, application-specific requirements – such as technical availability, product quality, specific operating modes or defined event scenarios. 
TÜV NORD assesses these requirements independently, transparently and on a project-specific basis.

We provide support throughout the entire plant life cycle

TÜV NORD supports operators, planners, contractors and investors with independent assessments, testing and expert evaluations throughout all project phases – from the initial concept through to modernisation and decommissioning.

  1. Project development and planning: In the early project phase, we assess technical concepts and provide a sound basis for reliable decision-making.
  2. Technical assessment and verification: Through independent assessments, testing and technical reviews, we support the verification process and the professional evaluation of technical documentation.
  3. Commissioning and acceptance: We support the inspection of plants and systems prior to handover for operation, providing transparency regarding their technical condition and compliance with defined requirements.
  4. Operation and optimisation: During ongoing operation, we provide independent assessments to help identify risks at an early stage, increase availability and highlight potential for optimisation. In the event of malfunctions or damage, we carry out appropriate analyses to enable measures to be derived to prevent recurrence.
  5. Modernisation and decommissioning: We also support conversion, upgrading and decommissioning projects with technical assessments, verification and quality assurance.

Practical Project Examples

At a data centre, frost damage to adiabatic dry coolers resulted in reduced heat dissipation, requiring servers to be temporarily shut down. TÜV NORD analysed the causes, identified factors relating to design, installation and operation, and supported the optimisation of the cooling system to help prevent similar damage in the future.

For an international infrastructure project, stringent requirements had to be met regarding voltage and frequency stability as well as system behaviour during sudden load changes. TÜV NORD reviewed the factory acceptance test programme and supported the acceptance testing at the manufacturer's facility. This enabled independent confirmation that the project-specific requirements had been met.

To further develop a cooling supply system with regard to high availability, TÜV NORD assessed various options as part of a concept study. The assessment was based on defined technical and operational requirements, providing a reliable basis for selecting the most suitable solution.

For a shore power supply installation, requirements relating to indoor air quality, automated monitoring, local climatic conditions, operation in a coastal environment, and the projected load cases had to be taken into account. TÜV NORD assessed the suitability of the planned ventilation and air conditioning concept and evaluated the consistency between the environmental conditions and the technical requirements of the components used.

An existing natural gas pipeline is being converted for the transport and storage of 100% hydrogen. TÜV NORD supports the commissioning process and assesses whether the commissioning programme takes into account all relevant availability requirements and operating scenarios. This helps ensure safe and reliable operation.
