What should a buyer check in a wind turbine installation method statement?

The short answer

Review whether the method statement gives competent personnel a coherent sequence using current approved documents, suitable resources and clear stop points. Check the interfaces between supplier instructions and site arrangements. A generic installation narrative or a contractor's previous project method is not automatically applicable to the actual turbine, tower, foundation and access conditions being supplied.

Reconcile the technical references

The method statement should identify the exact equipment configuration, installation drawings and relevant instruction revisions. Ask how the contractor confirms that site conditions match those documents before starting. Record prerequisites such as foundation release, component condition and availability of special tools. The buyer's review should focus on the agreed scope and interfaces, with competent specialists assessing the technical method. This FAQ does not establish a universal turbine assembly sequence or authorize a particular lifting, electrical or structural operation.

Check resources and coordination

Identify the responsible supervisors, competent personnel, handling resources and subcontractor interfaces. The plan should address how conflicting site activities, access and environmental conditions are managed through the applicable safety process. Ask who can stop work when conditions depart from the assumptions and who approves resumption. Emergency arrangements and safe energy control need appropriate task-specific planning. An equipment delivery schedule should not force the site team to proceed with a method that lacks its required resources or approvals.

Define the evidence of completion

List inspection and hold points, required records and the route for deviations or unexpected findings. Ensure that concealed work is checked before access is lost. Retain the released method statement and relevant changes with installation records. If the contractor proposes a different sequence, assess its consequences before implementation. A useful review produces a method applicable to the actual work and an accountable execution record, rather than another approved document whose assumptions no one verifies when the crew arrives.
