Increasing serviceability of WTG's using the "Ice protection"

Increasing serviceability of WTG's

Step 1

Once nearing the turbine, open the car backdoors in safe distance from the Wind Turbine (Approx. 100 meters from entry or according to guidelines from turbine owner)

Step 2

Drive backwards to the turbine and park the van with open backdoors facing the staircase/door to the wind turbine entry.

Step 3

While the technicians are still seated in the van, the upper part of the ice protection is raised to its maximum angle (Approx. 30°) by using a control box from inside the van cabin “safe zone”

Step 4

From “safe zone” inside the van cabin the raised protection is slowly maneuvered towards the wind turbine tower wall by using the control box.

Step 5

The turbine tower wall is protected by a large piece of cellular rubber to enable perfect fit between the ice protection and the turbine tower wall. Avoiding wear and tear on the tower wall.

Step 6

The technicians now have safe entry to the wind turbine well protected from ice falling from above. The technicians safely enter the turbine through a door separating the back area of the van and cabin.

Step 7

When service work has been finalized the technicians safely leave the turbine and enters the van cabin, from where the ice protection is maneuvered back to its driving position.

Mesh is used for ice protection being less sensitive to wind.

1 Layer

Consists of a nylon mesh with half- masks of 23mm, db nr 32 with tensile strength of 128 kg/string.

2 Layer

Consists of a polyethylene mesh with half-masks of 70mm, db 6,0mm with a tensile strength of 315 kg/string


The two layers of mesh are mounted on the frame on top of each other to ensure maximum tensile strength E.g. a piece of ice with the size of 300x300x50mm will fall onto the mesh on an area of 300x50mm. Here the tensile strength will be 5500KG.
