Computerised Planned Maintenance System or PMS
In earlier days, Maintenance Scheme and Record was completely on paper and included only a few of the most important jobs on board. As the awareness between people with respect to maintenance grew so did the system. Later the development of computers gave a new boost to Planned Maintenance System programs in shipping. It was in 1984 when the first computerised Planned Maintenance system or PMS was developed.
Below are few advantages mentioned of Computerised Planned Maintenance System. This Article is purely written with the examination point of view.
The conventional Maintenance Scheme consisted of card file system, each card pertaining to the maintenance of each equipment whereas in Computerised PMS, maintenance of all equipment is stored in one computer.
The conventional Maintenance Scheme was unable to see by the company, whereas in computerised PMS, the ship is able to sent the PMS files by email and company can readily see it.
In conventional maintenance scheme, the company is unable to track the records whereas in PMS, the company can track the records.
There was no procedure for backup or backup was not possible in the conventional Maintenance Scheme but in the new computerised Planned Maintenance system we have an option for backup of maintenance Data.
In Conventional Planned maintenance system it was difficult for the person incharge to look manually for the card of each equipment each time and was time consuming, this scenario is omitted with computerised PMS.
Computerised Planned Maintenance System is auto generated hence nothing can be missed out once all details are filled, whereas in older scheme, things can be missed out because of human error.
In computerised PMS the work which are pending are highlighted and flashes on screen, whereas in conventional maintenance scheme, the work which are pending are difficult to track.
In computerised PMS, the replenishment of spare is undertaken by the company as they can see the inventory of each equipment.
In computerised PMS, a list of items pending or due for maintenance or service at any particular time can be printed out, this can also be done on a conventional Maintenance scheme but is very time consuming and prone to human error of missing some items.
In Computerised Planned maintenance system, the work ca be carried out systematically so that no items are overlooked.
In computerised Planned maintenance system, most of the continuous machinery survey (CSM) inspection is carried out by Chief Engineer and so class survey has to come onboard only once a year, whereas in conventional maintenance scheme the surveyor has to come as continuous machinery survey is due.
