Cleaning strategy
Reactive strategy
The reactive strategy (i.e. putting out fires) is not considered to be part of the regular maintenance, and is only initiated after the occurrence of problems and incidents. Extent and costs of such emergency actions are unpredictable, and incidents and breakdowns are common.
Reactive cleaning measures are taken only after problems and disturbances occur. They have the objectives to e.g.:
-
Remove restrictions, obstacles, etc. in order to restore the hydraulic capabilities.
-
Remove odour causing deposits.
