A maintenance backlog is one of the most common challenges we encounter across offshore, energy and industrial operations. It is also one of the most misunderstood.
Backlog is a symptom, not the disease
When backlog grows, the typical response is to throw more resources at it — additional contractors, overtime, or a blitz campaign. These can provide short-term relief, but the backlog almost always returns if the underlying causes are not addressed.
Common root causes
- Preventive maintenance — PM volumes that are not optimised or rationalised
- Work identification — too much reactive work, not enough planned work
- Work management — weak planning, scheduling and execution discipline
- Data quality — incomplete or inaccurate equipment and maintenance data
- Spares availability — delays waiting on parts and materials
Where to start
The most effective starting point is rarely the backlog itself. It is the point upstream where work is being generated without sufficient control. That might be your PM programme, your work identification process, or your criticality framework.
By addressing the root causes, you do not just reduce the backlog — you change the conditions that created it.
