Cost-effective Condition-Based Maintenance for Offshore Industry

In this competency-building project funded by Sørlandets Kompetansefond, Teknova AS aims at establishing a leading research group within condition-based maintenance in the Agder region.

Cost-effective Condition-Based Maintenance for Offshore Industry

The common approaches for maintenance are scheduled maintenance where the parts are replaced at fixed intervals, or corrective maintenance where the parts are replaced after being broken. An alternative  is condition-based maintenance where the condition of the system is monitored through sensor measurements, and by using advanced mathematical methods the current state of the system as well as it remaining useful life (RUL) can be determined. By continuously monitoring the condition of the system and its RUL, it enables better planning of the maintenance, reduces the required amount of spare parts, increases the systems availability, and allows for large cost savings. This project aims at establishing Teknova AS as a leading research institute within this field.


  • Contribute to more effective industrial processes through optimizing reliability, maintainability and safety.


  • Develop competency on intelligent predictive maintenance systems that exploit all events, sensor measurements and other knowledge.


  • Form a leading research group in Agder to respond to industrial R&D need on condition based maintenance
  • Establish a common networking arena for exchange of knowledge and experience
  • Recruit high quality research personnel to Agder
  • Develop portfolio of collaborative projects.

The project takes a modular hybrid approach to the field of condition based maintenance and focuses on the following selected topics.
