Abstract
Podešavanje intervala održavanja temeljem iskustva, studija slučaja sustava brodskih kompresora
Highlights
The paper analyses the maintenance of the air compressor system (Figure 2) and the changes that have been made in that system over the time using data read in the computerized PMS
The downtime due to the change of the electric motor bearings was obtained by analysing the time required to complete the EMO001 work which varies from 6-36 hours, depending on the scope of the work performed and the person doing the operation [17]
Significance analysis is analysed through Significance index (SI), which shows the seriousness of the event and the magnitude of the expected loss associated with an unexpected event [20]
Summary
The paper presents the initial case of a research of analysing maintenance interval adjustment in the shipping industry. This case is an example of the adjustment of the maintenance interval carried out by ship’s crew on starting air compressor system. Maintenance interval adjustment proposal and actual adjustment were carried out based on user’s experience, after rechecking maintenance data and actual machinery condition, without theoretical approach or analysis. Missing actions in the process, i.e. theoretical analysis of the initial and modified maintenance, are performed using the MA-CAD method with a modified reliability testing and are described in the paper. Results obtained by the theoretical analysis are compared with the requested and performed modification of the Maintenance Plan and a conclusion about performed action has been derived.
