VTT ProperScan® to increase your overall equipment availability

High-quality tools and services for uninterrupted and safe operation over system lifecycle

When material performance mattersProperScan

VTT ProperScan®​ provides expert service with experimental and numerical analysis tools  to ensure safe and reliable operation of components and machine systems in energy, process and aviation industries. The service is scalable from component to system level.

  • Root cause analysis
  • Lifetime assessment
  • Risk management
  • Data analysis
  • Modelling


We give answers:

  • What is the current status of the plant or a component?
  • Failures due to corrosion, erosion or wear?
  • What are the most critical components of the plant?
  • How to react to changes in operational environment?
  • How can the risks be monitored and controlled?
  • How to target the actions?
  • When to perform the needed repairs?
  • How long can the plant be operated with present paramenters?

VTT ProperScan® offers services for uninterrupted operation

​​VTT ProperScan® service is based on gathered 500 person-years of combined scientific and practical experience on materials performance, manufacturing procedures and degradation in operation conditions.

Our expertise covers full range of materials performance aspects:

  • Root cause analysis
  • Environmental performance
  • Oxidation and corrosion
  • Fouling and deposit formation
  • Structural performance
  • Creep and creep-fatigue
  • Fatigue and wear
  • Long term performance
  • Microstructural changes
  • Aging


VTT ProperScan® service provides:


Root cause analysis to solve and understand failures in operating environments. Materials validation to test and manage corrosion and evaluate mechanical behaviour. Lifetime estimation to determine reliable remaining life or time to next service inspection.

Risk based inspection for accurate timing and targeting of in-service inspections and maintenance. Profiling for improved service and fleet management. Best operating practices by data-analytics for increased efficiency and reliability.

Scalable criticality audit to support for decision making in multiple levels for reliability, maintenance and investments. Maintenance program review for improved and cost-efficient maintenance. Scenario tool to provide information about risks and economical effects of competing development actions.

BALTICA Conference

A series of Baltica conferences concentrating on power plant maintenance and life management have been organised initiating from the 1980’s. The latest Baltica X was organised in June 2016. The Proceedings of the Baltica X conference are available: International Conference on Life Management and Maintenance for Power Plants.

Next BALTICA conference will take place in 2019.
