When SkySpecs releases inspection results in Horizon, customers who have access will be able to perform a detailed review of the damage identified on the blade. Roles that commonly are involved in reviewing these blade damages are: Blade Engineer/Operations Engineer/Wind Site Manager or Technicians/3rd party-vendor Technicians.
To assist with this process, Horizon provides the following features such as:
- Damage detail
- Damage photo detail
- Image filters
- Side-by-side comparison
This article explains how damage reviewers can use these features to create a workflow for evaluating damage photos and deciding on follow-up actions in Horizon.
Damage Detail Workflow
The damage detail page consolidates all of the available information about a particular damage into one location. Within this page, the user is able to view the damage image, review damage and inspection characteristics, review user-entered comments, review the chronology of all associated tasks and related damages, and make new actions associated with the damage.
Locate the damage detail page
1. Through the Inspections module, the user can navigate to the specific damage details, by expanding the damage information (clicking on the '+' button) for that row of information.
This will create a drop down expanding damage information to give the details as shown below. The information provided here includes the damage severity and type, component and material that is damaged, the radial location of the damage, and the damage annotation box dimensions. Inspection date is also included.
2. To navigate to the Damage detail page, user then clicks on View Details.
3. The previous step then loads the full overview of the damage details.

Damage Photo Details
1. The user can click on the red box in the damage photo view in the damage detail page. This pulls up the detailed image of the damage and features that enable the reviewer to perform a more detailed evaluation.
2. The user can then zoom in and out of the photo to perform a more closer look into the damage and evaluate the critical information.
For additional details of how to navigate around the damage photo: Article Link to Damage Photo Navigation
3. In the top left side of the window display, the reviewer is able to gather information about the location of the damage photo.
The damage information is shown in the bottom left hand corner of the screen, containing information such as the damage annotations and options for the reviewer to perform damage confirmation and/or task creation. For additional explanation of the interpreting the damage photo location: Article Link to Interpreting Radial Distances of Inspection Photos and Identified Damages
4. The user can then perform further review of the damage by using the Image Filter dropdown.
Two main options exist for applying image filters: Sharpen or Negative
Sharpen filter will simply apply an effect to the photo to give features a much sharper appearance. It is an enhancement of the photo edges and fine details so that the damage reviewer can more clearly see the effective depth and edge extent of the damage on the blade. This is particularly useful when the user want to view a hairline crack more clearly and to distinguish it from other features in the photo.
Negative filter is another image filter that is available in Horizon. This filter applies an inversion of the photo's colors and contrast, meaning that the image is reproduced with bright areas as dark, and dark areas as light. Again, this feature is available to the user to be able distinguish a particular feature on the photo.
To return to the original photo, the user should then choose the No Filter option.
The reviewer can also perform a more in-depth evaluation of the damage by evaluating the progression of that damage from a previous inspection (this is available to all Horizon customers who have had multiple inspection campaigns uploaded into Horizon).
This feature has been provided to allow for ease of comparing a side-by-side photo of the same damage between previous inspections to the current one being viewed.
Performing such a review would:
- Enable year-over-year (YoY) progression evaluation of the damage.
- Provide further details on whether the damage has evolved to a state or condition that is justified by the severity that it is assigned in the latest inspection.
- Enable a holistic review of damages that has progressed between inspection intervals.
- Enable the appropriate action to be taken via task creation for follow up inspections in the case of continual monitoring or corrective repair for serious or critical damages.
- Enable a review and confirmation of a previously identified damage that has now been repaired or a check of whether the damage repaired has held up over time with subsequent inspections.
There are 2 main ways to access the side-by-side damage photo comparison:
1. Access through Damage Detail window:
Chronology Section: This section as depicted below tracks the chronology of damage and tasks created, and is an easy way to have an overview of new inspections of the same location tracking the same damage over time, as well as maintenance inspections or repair tasks that has been carried for this specific damage over time.
The damage chronology contains a link as shown where the mouse button is in the screenshot below.
Clicking on this will then pull up the side-by-side photo for comparison.
2. Another way to pull up the same side-by-side photo comparison view is when the user has already clicked on the red box in the Damage Detail window to pull up the damage photo.
Using the Inspection date dropdown, the user is then able to click on the Compare link to pull up the side-by-side as seen above.

Other comparisons are also possible in Horizon if the user wishes to view the photos for other blades in the same damage position as the current one in view. This can sometimes come in handy when the review would like to include further investigation of whether this damage occurs in the same location as on other blades on the same turbine.
To perform this, the user can use the Blade dropdown to select the blade to be compared.
Performing a detailed review of the damage photo is one of the critical steps in the damage evaluation workflow. This allows the damage reviewer of the damage to further:
- Confirm the damage (Article Link to Workflow for Damage Confirmation).
- Create a follow-up action such as a tasks (inspect or repair) for that particular damage (Article Link to Workflow for Task Creation).
- Include any comments to the damage in the Comments feature as a means of communicating with other stakeholders on pending actions or damage review results.
