Wind Turbine Spare Parts: Identity & Revision Records
A replacement enquiry needs the identity and revision of the installed component, not just its appearance. Keep the part record connected to the turbine configuration and request applicable compatibility evidence before a purchase or substitution is treated as approved.
Identify the part and the configuration it belongs to.
A catalogue label, photograph or similar mounting shape can help begin an enquiry. It cannot by itself establish interchangeability, availability or an authorised replacement for the installed turbine.
01 / Installed identity
Connect the component to its assembly.
Record the turbine model, available serial identity, relevant assembly reference and documented changes since installation.
Record the turbine model, available serial identity, relevant assembly reference and documented changes since installation. For the component, retain the supplier part number, label, drawing reference and revision where available. Keep a labelled photograph tied to this record.
Distinguish a component identifier from a product model name. FD14-50KW, for example, identifies a turbine model rather than every part inside it. Earlier hydraulic-yaw records must not be assumed to identify components in the current electric-motor yaw configuration.
02 / Request purpose
State why a replacement or spare is being discussed.
Separate an investigation of a reported fault from planned spare provisioning or an approved replacement request.
Separate an investigation of a reported fault from planned spare provisioning or an approved replacement request. Include the responsible service team’s disposition where available. A symptom is not proof that the photographed component is the cause or the part that needs changing.
A request record can contain request_id, installed_part_reference, reason, applicable_service_record and information_missing. Retain the observation and diagnosis separately. The event-reporting guide helps organise supporting evidence without prescribing a repair.
03 / Revision review
Ask which differences matter for the installed package.
Request the applicable replacement identification and the evidence linking it to the installed assembly.
Request the applicable replacement identification and the evidence linking it to the installed assembly. Relevant differences may concern geometry, fastening, electrical limits, firmware, signals or service requirements. The responsible reviewer should identify which apply to the particular request.
Do not infer interchangeability from similar dimensions, equal kW, matching connectors or a newer revision date. A substitute can affect other documents and components. Keep an explicit supplier or design-authority response rather than relying on an informal statement that a part looks equivalent.
04 / Provisioning scope
Discuss availability without assuming an inventory offer.
Ask which items can be quoted for the identified equipment, their applicable versions and what documentation accompanies them.
Ask which items can be quoted for the identified equipment, their applicable versions and what documentation accompanies them. Record availability, lead time, quantity and commercial terms from the actual response. This guide establishes no stock list or separate blade, generator or yaw-part sales programme.
For a remote project, describe access constraints and the consequence of waiting for an approved replacement. The owner and service provider can discuss a provisioning plan using the real service requirements. Do not invent a universal spare quantity or replacement interval for the five-model range.
05 / Stored spares
Retain identity and condition while an item is held.
If approved spares are obtained, keep their labels, revision evidence and storage instructions with the inventory record.
If approved spares are obtained, keep their labels, revision evidence and storage instructions with the inventory record. Record receipt date, location, condition observations and any supplier-defined preservation requirement. Distinguish a stocked item from one already assigned to a particular repair.
Check the documentation when the installed equipment changes; an old spare may require renewed applicability review. Use the storage guide to organise condition and movement records. An unused item is not automatically a current compatible replacement.
06 / Replacement record
Update the configuration after authorised service work.
Ask the responsible service team to retain the approved part identity, work record and applicable return-to-service evidence.
Ask the responsible service team to retain the approved part identity, work record and applicable return-to-service evidence. Record the removed and installed components and any associated configuration change. This page provides no removal, fastening, electrical replacement or reset procedure.
Keep the final disposition with the equipment documents so future enquiries use the actual installed version. NASA’s configuration-management principles explain the value of consistent product and document identities; they do not certify MARSTON service practice. Request a part-specific review through the agreed support channel.

Prepare the information for this review.
Use the checklist to organise the project information. Mark unavailable items and retain document references.
| Review item | Information to provide | Purpose |
|---|---|---|
| Installed assembly | Turbine identity, component label and document revision | Locate the actual component. |
| Request context | Service disposition, provisioning purpose and missing information | Separate diagnosis from purchasing. |
| Compatibility evidence | Approved part reference and affected interfaces or documents | Review interchangeability. |
| Supply response | Confirmed availability, scope, terms and documentation | Avoid assuming a general spare offer. |
| Lifecycle record | Receipt, storage, authorised work and final configuration | Preserve part traceability. |
Engineering questions.
Can a photograph identify the right replacement?
It can support an enquiry, but the component and assembly identifiers and applicable revision evidence are also needed.
Does a newer part revision automatically fit?
Check its applicability and affected interfaces for the installed configuration. Newer does not establish interchangeability.
Does this page list available MARSTON spare stock?
No. Availability and separate supply require a response for the specific component and equipment.
Should I buy a replacement based on an alarm?
Keep the alarm context and obtain the responsible service assessment. An alarm alone does not establish which component needs replacement.
Can one spare be used across all five turbine models?
Use model- and assembly-specific evidence. No universal shared-part compatibility is claimed.
What should remain after authorised replacement work?
Retain the approved part identity, service record, affected document revisions and required return-to-service evidence.
Technical enquiry
Bring your project information to the discussion.
A replacement enquiry needs the identity and revision of the installed component, not just its appearance. Share the available information and the equipment scope you want reviewed in a technical quotation.
