This is when equipment is left untouched until a breakdown occurs. At this time, the equipment is repaired or replaced and any other specified maintenance procedure carried out.
There are several disadvantages to breakdown maintenance:
A serious breakdown of equipment may cause enough downtime to put the ship out of commission until it is repaired.
Several breakdowns occur simultaneously, the available manpower, skills of the crew or knowledge in the field of the breakdown may not be sufficient to cope adequately, resulting in more delays
Some items of equipment may need the specialist services of the manufacturer to carry out repairs, which are expensive and may cause further delays.
