Wind energy

An 8D for a turbine failure, accepted by the people who must act.

Your Name runs 8D problem solving for field failures on wind turbines and their gearboxes, bearings, blades, pitch systems, and converters. For an owner, an OEM, or a supplier.

What the file has to contain

  • A containment decision

    Which turbines to stop, inspect, or keep running, and which sister turbines are in the population.

  • Both causes

    Why the defect was made, and why it escaped. A file that names only one of them is not finished.

  • A close with evidence

    The action is in place, or the file states the later date a crane, a weather window, or a teardown requires.

Who the file is for

Owners, turbine makers, and the suppliers of the failed part.

  • Owner

    Several turbines of one type have failed. The rest of the fleet still needs a decision: stop, inspect, or keep running.

  • OEM

    A field complaint needs containment, and an 8D the owner can answer.

  • Supplier

    A component has come back, the customer clock is running, and the installed fleet is not yet defined.

Two ways to run the same file

A led resolution does not require the software. Each case states whether the work is for the owner, the OEM, or the supplier. A named person accepts the root cause.

01

Led resolution

Your Name runs the 8D on one open issue, from the sister turbines through a report the other party can answer.

02

[Product name]

Resolution software for the team that will run the file itself. It drafts the problem statement, an Is / Is-not, and a 5-Why. It flags a missing escape cause, a missing sister population, a missing clean point, or a close with no evidence. Use is a pilot. The software does not accept the root cause.

The file, in order

The same eight disciplines for a led resolution and for [Product name].

  • D1–D3 24 hours
  • D1–D5 5 working days
  • D1–D8 20 working days

Where a crane, a weather window, or a teardown sets a later date, the report states that date and the reason.

  1. D1

    Team

    Name the people who can describe the failure, the process, and the escape path.

  2. D2

    Problem

    State the failure on the component and the turbine type: what is seen, where, since when, and how many.

  3. D3

    Containment

    Decide which turbines to stop, inspect, or keep running. Define the sister population by serial number, batch, build date, site, and operating hours.

  4. D4

    Root cause

    Separate why the defect was made from why it escaped. A named person accepts both causes.

  5. D5

    Corrective action

    Choose the action that removes those causes, and record what was considered and set aside.

  6. D6

    Implement

    Put the action in place and show that it worked. If the hardware date is later, the file says so.

  7. D7

    Prevent

    Change the check that let the defect escape, so the next batch and the next site do not repeat it.

  8. D8

    Close

    Close on evidence. Recognize the people who did the work. A close with no evidence stays open.
