How we work

Practical, from the first site visit.

No long reports that sit on a shelf. Every engagement follows the same four steps, sized to the problem in front of you.

  1. 01

    Walk the site

    We start on the ground with your operators and maintainers, looking at the equipment where it works.

  2. 02

    Find the cause

    We review history, symptoms and operating conditions to separate the root cause from the knock-on effects.

  3. 03

    Plan the fix

    You get clear, costed options for repair, refurbishment or replacement, in priority order and plain English.

  4. 04

    Keep it running

    We help put maintenance routines and records in place so the same failure does not come back.

Repeat failures

The fault you fixed last month is back.

Repeat failures hide in the gaps between shifts. We bring the history together so the pattern is visible, then fix what is really causing it.

  1. 01

    Record it against the asset

    Every fault, photo and repair is logged on the equipment itself, not in someone's notebook.

  2. 02

    Look for the pattern

    We read across shifts and months to see when the same fault keeps coming back.

  3. 03

    Fix the cause, not the symptom

    We investigate why it repeats and plan the repair, refurbishment or change that stops it.
