Narva power plants, Eesti Energia, Estonia, asset management process development 2016–2017

Fortum eNext has created a modern asset and maintenance management process to Narva power plant. In the project the plant’s maintenance strategy was renewed and upgraded by taking environmental, economical and safety aspects into consideration.

Narva Asset Management Project

Case description 

The project was started by performing a criticality analysis, which is a systematic and analytical method to identify and classify power plant components, equipment, systems or other production assets, taking  the required level of equipment redundancy into consideration. This analysis served as a prejudice for further development of maintenance and repair strategy optimisation and spare part philosophy on the basis of risks and reliability. The project included also the development assessment of Computerized Maintenance Management System (CMMS), definition of KPIs and other performance indicators, as well as planning preventive maintenance actions for certain critical equipment.

Customer benefits

The criticality class provided extensive information about the expectations for equipment reliability as well as its role in the production process, including environmental, economical and safety aspects. The equipment criticality analysis helped also determining priorities for the maintenance and repair planning and execution, as well as to promote risk awareness and management.

The project resulted in a powerful road map to:

  • Create the Preventive Maintenance (PM) actions and programs by forming reliable maintenance strategy
  • Form principles for spare part and stocking strategy and implement associated purchasing processes
  • Develop CMMS to support operation and maintenance activities
  • Design and determine the Key Performance Indicators (KPIs). This helps the company to assess the execution of selected strategy and determine bottle necks in the maintenance and repair processes.
