When equipment is regularly inspected and maintained according to a manufacturer’s timetable and described procedures that specify the actual work to be done to prevent equipment failure.
Planned maintenance is carried out at fixed regular intervals, whether the equipment needs it or not.
The aim is to prevent breakdown and this type of maintenance has the advantages:
• Fewer breakdowns and reduced downtime produces higher levels of operating efficiency
• maintenance is carried out at times favourable to the operation of the ship
• more effective labour utilisation because maintenance is carried out at times favourable to the ship’s staff
• replacement equipment can be ordered in advance
• equipment is maintained in a safe condition with reduced possible dangers
• where a specialist manufacturer’s services are required, these can be obtained at convenient times to suit the ship operation
• spare parts required for repair can be ordered in advance
• short-life components are replaced at scheduled intervals.
