Maintenance process adjustment based on Computerized PMS data

In order for machines and devices to work properly during a long period of exploitation, it is necessary to have an adequate maintenance plan. The initial maintenance schedule for each machine is created by the manufacturer, using their knowledge and experience in operation with this device. Maintenance recommendations were made for all devices of this type ; the manufacturer could not foresee all the conditions under which the device would operate. During the lifetime of a device, it is possible to modify a maintenance plan, taking into account the conditions in which the device is operating. Planned maintenance systems must be able to keep all maintenance records. By systematically analysing this data, after a sufficiently long period of exploitation, it is possible to suggest modifications to adapt the initial maintenance plan to the operating conditions of that device. In doing so, the modifications must not affect the performance and safety of the ship. The maintenance plan adjustment using data from the Planned maintenance system is shown in the example of the engine room fan system consisting of four centrifugal fans. The fans work independently of each other and provide air for engine room machinery. Maintenance of the fan system is included in the computerized Planned maintenance system. It is keeping records of previous maintenance, which, after a sufficiently long period of time, provide sufficient data for analysis, i.e. for the calculation of reliability. Changes to the maintenance plan which will improve the maintenance system can be based on that calculation.
