Maintenance is the work that decides how large the next repair is. Wastage caught early is a patch. The same wastage found at survey is a renewal, a class condition and a dock booking.

Corvaden works to the owner’s planned maintenance system rather than proposing a parallel one. Jobs are executed against the vessel’s own work list, recorded in a form that files against the existing entry, and closed out with what was found as well as what was done.

Where the work suits it, riding squads carry this out during passage, which takes port time out of the calculation entirely.
