Planned Maintenance
Maintenance that holds up in a survey
Work orders, spares, running hours and statutory tests for the whole fleet, with the evidence a class surveyor asks for attached to every job.
Down in the engine room, every machine keeps its own history
Up to the maintenance board, where jobs, hours and spares meet
The maintenance loop, closed
Work orders with twelve states
Draft to closed under maker-checker approval. The server refuses a self-approval and names separation of duties when it does.
Completion gated on evidence
Required photos, certificates and a snapshotted checklist are rebuilt server-side before a job is allowed to close.
Five maintenance triggers
Calendar, running hours, dual with whichever comes first, manual, and condition rules that re-arm on hysteresis.
Spares that reconcile
Stock draws prefer the vessel’s own stores, split across locations atomically and journal every movement. A shortage parks the job in waiting parts.
Statutory tests and IHM
Fifteen function tests with their regulation references, and a Hong Kong Convention hazardous-materials register across Tables A to D.
Deferrals with reasons
Moving a planned job records who moved it, from when to when, and why. The log a surveyor reads when a job has slipped.
The work-order board, as the crew sees it
A real register, rebuilt in code: the queue, the statuses and the approvals exactly as they run aboard.
