Ageing Management and Plant Life Management

Investments in large production units can be valorized only by their subsequent effective long-term operation. We use sophisticated procedures, diagnostics, and control programs from nuclear energetics to manage the life cycle of equipment and production units in other areas of the energy industry.

We deal with aging management and extend the lifetime of the equipment comprehensively and long-term. We manage the aging of specific plants, and we are the authors of many certified programmes and methodologies.

Programme implementation procedures include maintenance of the project base database, ageing management plans, and in-service inspections.

Optimizing the operation of energy sources and equipment

Elaboration of studies and documentation for optimization of energy operations.
Studies and documentation for the next phase of the project can be processed for energy sources as a whole as well as for part of the operation.

The objective of the optimization of energy generating units is to improve the efficiency of energy generation, reduce losses and operating costs or, from the perspective of change, the operation of the unit, and usually includes the following activities:

  • Analysis of current operation;
  • Targeting possibilities for improving the efficiency of operation - equipment modernisation, modification of connection and operating mode;
  • Creation of a computation model, definition of margin conditions, calculation of reference state, taking into account the target modifications;
  • Impact assessment of the monitored change on thermal efficiency;
  • Impact assessment of the implementation of change on the equipment affected;
  • Optimisation of parameters of the main electrical equipment, protections and automatics, maneuverability check;
  • Optimisation and design of electrical diagrams;
  • Optimisation and design of electrical protections and automatics, protection selectivity and setting.

Design activities:
