Planned Maintenance System in shipping

The PMS - Planned Maintenance System is a paper/software-based system which allows ship owners or operators to carry out maintenance in intervals according to manufacturers and class/Classification society requirements. The maintenance, primarily supervised by the onboard 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 societies like American Bureau of Shipping, Germanischer Lloyd, Lloyd's Register, Bureau Veritas or Det Norske Veritas, etc. All these classification societies are members of IACS (International Association Of Classification Societies Ltd). Having a planned maintenance system on ships is now mandatory as per ISM (International Safety Management Code).
