Which records should be retained when wind equipment is removed from service?

The short answer

Retain records that identify the equipment removed, its final operating status, condition, custody transfer, remaining hazards and authorized disposition. Coordinate technical work with competent people and check applicable environmental and legal requirements locally. A decommissioned label should close the asset's operating status while preserving the information needed for safe handling, later analysis or an authorized transfer.

Define the removal scope and authority

List the assets and interfaces included, the reason for removal and the applicable approved plan. Identify who controls isolation, dismantling, lifting and handling through task-specific procedures. This FAQ does not prescribe those operations. Preserve the final configuration and relevant condition findings before equipment changes hands. If only one assembly is removed, clearly distinguish it from the status of the remaining installation so the register does not imply that the complete wind project has been safely closed.

Record custody and residual conditions

Identify components, parts and materials transferred to storage, repair, resale, recycling or disposal. Record relevant condition restrictions and the instructions or information passed to the receiving party. Do not describe an item as reusable solely because it was removed without visible damage. Any proposed reuse needs its own technical assessment. Qualified parties should determine waste classification, transport and disposal obligations for the actual materials and destination; a generic wind turbine description does not establish those requirements.

Close the asset history carefully

Retain removal dates, responsible parties, applicable records and final disposition evidence. Update stock, service, monitoring and document systems so retired equipment is not accidentally treated as active or available for installation. Preserve required records for the appropriate retention period identified by responsible advisers and project procedures. The resulting history should allow a future reviewer to understand what left service and where it went. It is separate from a claim that dismantling was completed by a particular safe method or that all environmental obligations automatically ended.
