Impact of offshore wind turbine decommissioning scenarios on ecosystem services.
How the app works
The full linkage framework represents the links between pressures, components (functional groups of organisms living in an offshore wind farm), ecosystem functions and ecosystem services. All links are scored for intensity, direction (positive or negative) and spatial scale (close to turbine/offshore wind farm/beyond offshore wind farm). Where possible, we used peer-reviewed scientific literature (published before June 2025) to support the scores. When needed, we provided expert statements as support. All literature and statements are documented in the app. The peer-reviewed literature can be accessed by clicking a link in the linkage framework.

Decommissioning scenarios
Scenario 1
No decommission
Scenario 2
The turbine is fully removed, the scour protection layer remains in place. All pressures related to the presence of the turbine are removed from the environment. All potential effects related to the presence of the scour protection layer are still in the linkage framework.
Scenario 3
The turbine is partly removed (cut 3m above the sea floor), the scour protection layer is fully removed. All pressures related to the presence of the scour protection layer are removed. Pressures related to the upper parts of the turbines are removed from the environment, the same holds for the organisms colonizing the upper parts. As such, turbine effects are caused by pressures to the lower part of the turbine, and the organisms living there.
Scenario 4
The turbine is partly removed (cut 3m above the sea floor), the scour protection layer remains in place. Pressures related to the upper parts of the turbines are removed from the environment, the same holds for the organisms colonizing the upper parts. As such, turbine effects are caused by pressures to the lower part of the turbine, and the organisms living there. All potential effects related to the presence of the scour protection layer are still in the linkage framework.
