Industry-wide Benchmarking
BTB Jansky Services, Industry-wide Benchmarking

The continuous assessment of process efficiency requiresa continuous flow of relevant process data, verified for plausibility regarding the process condition and performance

In order to compare technical and business processes and their key data among a number of (similar) power plants, the data needs to be standardized according to several factors, e.g. plant type, organizational structure, plant age, local legislation, etc.

BTB Jansky owns and maintains a broad customer plant database defining the benchmark (best-practice) plant for numerous technical and business processes and generates recommendations on the measures that need to be taken to reach this benchmark.

The result of the industry-wide benchmarking project is a cost-efficient, technically optimized and safely operating plant. The approach is holistic and recommendations for benchmark are including the following areas:

• Maintenance planning
• Plant organization
• Business processes
• Documentation




Defect Analysis
BTB Jansky GmbH, Services Defect Analysis

Component failure can be caused by incorrect selection of materials, incorrect dimensioning, manufacturing defects or unacceptable loads. If a component has failed or has been damaged, a defect in-depth analysis can identify the reasons for the failure

The mechanics of the damage can be deduced from the point in the component where the break occurred, the characteristics of the material at the cross-section of the break, the geometry of the part that failed, the point where the defect started and the surface of the fracture itself. We have our own scanning electron microscope with connected EDAX for materials chemical analysis. In order to calculate the load parameters that caused the damage, we use pipework programs (static and dynamic analysis) and ANSYS Finite Element (FE) programs. When required, we commission examinations of original material samples under operating conditions (load, temperature).

Knowledge of the causes of the failure or damage is used as a basis for recommendations such as a change in the selection of materials, manufacturing processes, geometry or loading in order to prevent the defect from reoccurring. We take temperature and strain measurements for our customers for the purpose of optimizing components and designing components and systems. With the ANSYS program we can simulate and analyze elastic and elasto-plastic stresses (including contact problems) and calculate temperature fields.

Maintenance Concepts
BTB Jansky - Services Maintenance Concepts

Optimization of current maintenance strategies, saving costs while increasing plant safety and availability

With our philosophy of condition-based maintenance our strategy is that we only replace components in technical systems when they are nearing the end of their service life. In contrast, the procedures for preventive time-orientated main­tenance are carried out according to fixed cycles.

The benefits of this policy for you are the resulting cost savings and the assurance that you have taken preemptive action that is likely to prevent operational failure. The transition from a time-oriented to a condition-based maintenance should only take place in combination with a cost-benefit concept. For this purpose the costs of the single maintenance measures should be known as well as the consequences of a possible component failure for plant operation.


  • Development of a cost-benefit concept to analyze technical components
  • Choice of suitable diagnostic method:
    • Vibration measurement
    • Process data reconciliation
    • Defect analysis
    • Thermography
  • Generation of resulting maintenance concept
