Maintenance planning that survives contact with the fleet

Maintenance planning fails in two directions: too rigid to absorb operational reality, or too loose to drive class compliance. The fleets that get it right design the plan around the operating profile, not the textbook interval.

The right question is not 'is the PMS up to date'. It is 'does the next thirty days of planned work survive the next thirty days of operations'.

A chief engineer rolling a critical job by ten days because the next port has the right berth and the right class window. A superintendent who sees the same fleet picture as the manager — with the same data, not a copy.

Plans that bend without breaking are operational plans. Plans that break instead of bending are paperwork.

Track plan-to-actual at the job level, but report it at the fleet level. Surface the jobs that have moved more than twice — those are the early signals of a planning assumption that no longer holds.

Tie maintenance plans to operational events (port calls, dry-docks, surveys), not just to running hours.
