Machine-learning health models for hydropower maintenance

Statkraft detected sensor changes before a bearing failed 12 hours ahead of its scheduled inspection

Problem

Aging hydropower equipment required costly maintenance. Risk assessments relied heavily on physical inspections and manual calculations.

Approach

Statkraft started a machine-learning pilot at Kvilldal in 2017 and tested a health model at Jostedal. The model detected small sensor changes, prompting an inspection scheduled 3 weeks later. A thrust bearing failed before that inspection. The team then reported installing extra sensors and maintaining weekly contact with site staff.

Results

12 hourstime before the scheduled inspection when the thrust bearing failed, according to StatkraftCompany's own claim[1]

Takeaway

Detecting deterioration did not establish how urgently maintenance staff needed to intervene.
