Blade Inspection Robot Deployment and Recovery
How to plan it: agree the route, approvals, stop conditions and recovery responsibilities before the robot enters the blade.
This article is a planning guide for asset owners and qualified inspection teams. It does not provide robot operating instructions, turbine isolation steps or hazardous rescue techniques. Execution belongs to competent personnel working under the site’s approved system of work and applicable OEM procedures.
1. Write a bounded mission brief
Give the mission a clear beginning and end. Identify the turbine, blade, cavity, inspection objective and planned reporting output. Record which areas are included and which require separate approval or another inspection method.
Define completion in observable terms: the agreed images and location references have been captured, any incomplete areas have been recorded, the equipment has been accounted for and the work package has reached its authorised closeout point.
Keep the inspection target separate from the commercial schedule. A planned outage window cannot demonstrate that a particular cavity is traversable. Resolve the access assumptions — the access and compatibility checklist is the place to start — before using them to commit resources.
2. Build the approval and responsibility matrix
A plan should identify roles, not merely list equipment. Every decision needs an accountable role before mobilisation.
| Planning decision | Accountable role to assign | Evidence needed before release |
|---|---|---|
| Inspection scope | Asset owner or appointed engineer | Defined zones, evidence requirement and exclusions |
| Equipment suitability | Robot supplier and qualified inspection lead | Configuration review and current instructions |
| Turbine access and isolation | Authorised site/OEM personnel | Approved site-specific work controls |
| Deployment readiness | Appointed work supervisor | Completed checks and closed hold points |
| Stop and escalation decisions | Named operational authority | Agreed triggers and communication route |
| Equipment recovery | Qualified recovery lead | Approved normal and contingency arrangements |
| Return to service | Site-authorised release authority | Required closeout and equipment reconciliation |
The table is a planning template. It does not allocate legal duties or replace the operator’s own organisational arrangements.
HSE’s maintenance guidance supports using competent personnel, manufacturer information, planned safe systems and appropriate isolation. The detailed controls must come from the turbine and equipment procedures applicable to the site.
3. Review the route and supporting equipment
The deployment review should cover both the robot and its journey to the working position. Confirm handling arrangements, available space, cavity access and the interfaces needed for the selected system. Record unresolved geometry or surface-condition questions as hold points.
Ask the supplier to identify the configuration’s documented power, communications and cable-management requirements, where applicable. Do not assume that every platform uses the same arrangement or that a cable is approved as a retrieval device.
The WIT-BR60 overview describes negative-pressure adhesion, illuminated camera views and location-linked reporting. It is a source for product context, not a site-specific deployment or recovery procedure. Request the controlled instructions and configuration review needed for the proposed mission.
4. Set a realistic schedule boundary
Divide the work estimate into access preparation, approved turbine preparation, equipment setup, inspection, planned recovery, data checks and closeout. Identify dependencies between teams.
WIT-BR60’s published 70 m / ≤60 minute value concerns one cavity over a 70 m internal area within a 95 m blade, with the documented setup and an unobstructed path. It is not a total site-visit duration. Keep that qualified product value separate from the outage estimate and from the separate coverage statement. The guide tointernal blade inspection coverage limits provides further context.
Include contingency time based on the actual work package. Do not invent a standard recovery allowance or promise that a particular interruption can be resolved within the outage window.
5. Agree stop conditions before deployment
The team should know which conditions require suspension, who receives the report and who can authorise continuation. Thresholds and immediate responses must come from the approved procedures, rather than this article.
| Condition to address in the plan | Decision to settle in advance |
|---|---|
| Unexpected obstruction or geometry | Who reviews the changed route or scope? |
| Loss of required control, communications or monitoring | Which approved contingency applies? |
| Images fail agreed quality requirements | Who decides whether capture must be repeated? |
| Site or environmental conditions change | Who reassesses the work authorisation? |
| The planned return route becomes uncertain | Who controls recovery escalation? |
| Available work window is reduced | What scope can be deferred without ambiguous reporting? |
Include a short briefing record confirming that the relevant people understand these boundaries. Schedule pressure must not change an approved limit.
6. Separate equipment recovery from human rescue
The recovery plan should distinguish normal retrieval, equipment-fault contingencies and emergencies involving people. Specify the responsible specialists, authorised methods, supporting resources and escalation contacts for each category.
A stranded robot does not authorise personnel to enter the blade or improvise a pulling arrangement. Any proposed change requires review through the site’s approved controls. This guide intentionally provides no retrieval mechanics, force limits, attachment methods or rescue manoeuvres.
Where confined-space work is involved, HSE calls for appropriate emergency arrangements before work begins and warns against relying solely on public emergency services. Consult itsconfined-space guidance andApproved Code of Practice. These are Great Britain references; qualified site personnel must apply the relevant jurisdiction’s requirements.
7. Close out the equipment and evidence together
Use a defined handover checklist:
- Equipment and accessories reconciled against the mobilisation inventory
- Recovery status and any abnormal events recorded
- Completed and incomplete inspection zones distinguished
- Original capture files and agreed location references retained
- Observations separated from reviewed classifications
- Outstanding technical questions assigned
- Worksite restoration and return-to-service approvals completed by authorised personnel
The sample inspection report illustrates a reporting structure. It is not evidence that an inspection has passed or that a turbine is ready to operate. What the delivered record has to contain is set out in what a blade inspection report should include.

Decision support
Frequently asked questions
When should the recovery plan be approved?
Before deployment, with its applicability checked against the actual configuration and route.
Can the advertised run time set the outage duration?
No. The total programme includes preparation, access, recovery and closeout, plus project-specific dependencies.
Who approves a changed recovery approach?
The authority identified in the site’s work-control arrangements, supported by the relevant qualified specialists and OEM requirements.
Does this guide tell me how to retrieve a stuck robot?
No. It intentionally gives no retrieval mechanics, force limits, attachment methods or rescue manoeuvres. A stranded robot does not authorise anyone to enter the blade or improvise a pulling arrangement; any change goes through the site’s approved controls.
