Visualize Maintenance Data to Identify Safety Issues and Opportunistic Maintenance Possibilities

In this paper, a proposed visualization method for identifying safety issues and opportunistic maintenance possibilities is presented. The focus is on the practicability of opportunistic maintenance and hazard identification, which is lacking in both literature and industry (i.e. case company). The proposed method uses visualization and system drawings for communicating the potential issues and opportunities to maintenance planners. The visualization is data-driven and uses common maintenance data for highlighting potential safety issues and opportunistic maintenance possibilities on system drawings. The applicability of the method was tested at a case company and the results confirm that benefits can be achieved by using the proposed method. Through the use of the method, issues and opportunities were identified which would not have been discovered or would have taken a considerable amount of time to derive using the existing maintenance planning procedure.
