5.4.4. Decommissioning

This page is only in English

No projects or wind farms have completed their estimated lifecycle of 25 years. Decommissioning the project will consist of the removal of the devices and foundations from the sea in order to bring the area to the state which it was before the project, which is usually the requirement in most projects. Although the device removal would not be difficult, it will be more complex for the foundation structures. Mono-pile foundations or multi pile foundations, which are generally pile driven into the seabed, will involve a complex procedure to remove. Gravity based structures will also be very expensive due to their immense weight.

It is possible that foundation structures could be reused for the installation of other turbines in the same area provided that they are suitable for the technologies available at the time of decommissioning.
