Planned Maintenance System
From Wikipedia, the free encyclopedia
The PMS - Planned Maintenance System is a paper /Software based system which allows ship owners and/or operators of a vessel/ship maintenance in intervals according to manufacturers and class/Classification society requirements. The maintenance, primarily supervised by the on board personnel, is then credited towards inspections required by periodic surveys. The planning and scheduling of the maintenance, as well as its documentation, must be made according to a system that is approved by Classification society like Germanischer Lloydetc.Which is now mandatory as per ISM (International safety management).
The PMS program must be submitted in English language but the instructions and history may be in the most suitable language. Maintenance summaries in English are required.
Damages which may be presumed to require class inspection are to be reported to a surveyor of Germanischer Lloyd.
An annual survey is needed to review the status of equipment. A special survey every five years verifies that the PMS program is functioning. The PMS surveys will be harmonized with other periodic surveys.
[edit] General
The planned maintenance systems are usually comprehensive preventive maintenance programs including machinery, workshops, accommodation etc. It was created by Anthony J Ruffini, in 1963. This type of survey arrangement can be granted to any type of ship.Presently, the survey arrangement based on planned maintenance might include machinery and automation equipment - included in the Continuous Machinery Survey scheme.
All maintenance work carried out is to be documented by the planned maintenance system. A maintenance system documenting the maintenance of the category "Classification Survey" only is considered as insufficient.
[edit] Requirements to Planned Maintenance Systems
- Inventory content, i.e. items/systems included in the maintenance program.
- Maintenance time intervals, i.e. time intervals at which the maintenance jobs are to take place.
- Maintenance instructions, i.e. maintenance procedures to be followed.
- Maintenance documentation and history, i.e. documents specifying maintenance jobs carried out and their results.
- Reference documentation, i.e. performance results and measurements taken at certain intervals for trend investigations from delivery stage.
- Document flow chart, i.e. chart showing flow and filling of maintenance documents as planing cards, job cards etc.
- Signing instructions, i.e. who signs documents for verification of maintenance work carried out.
Documentation on maintenance of the category "Classification Surveys" carried out on items/ systems covered by the Rules is to be signed by the Chief Engineer. With computerised systems the access to updating the maintenance documentation and the maintenance program should be possible for the Chief Engineer only.
The description and documentation of the planned maintenance system are to be in the English language. The maintenance instructions and maintenance history on job cards may, however, be in the language most practical and suitable for the maintenance crew. In such cases the maintenance history and job cards is to be given a summary in English in the maintenance documentation.
For ships trading in specific areas, e.g. ferries, planned maintenance systems using other languages than English may be accepted. This arrangement is automatically cancelled in case of change of trade.
The maintenance system is to produce a documentation which is useful as a basis for the annual survey of the PMS.
Computerised systems are to include back-up disks or cassettes which are updated at regular intervals.
