5.4 Scenario Analyses
Our analyses focus on narrative scenarios that may lead to mechanical (and corrosion) damage to the wind turbine foundation. Scenarios that could lead to damage
of the aquaculture construction or the supply/maintenance vessels are not (yet) included. These risks can only be investigated at a later stage when the operational
processes of maintenance and harvesting are known in detail.
Two scenarios that may occur and questions that arise are:
1. Impact. Drifting aquaculture construction strikes the turbine foundation.
Is there a risk of significant damage to the foundation?
2. Extra drag force. Drifting aquaculture construction gets stuck around the turbine foundation, increasing its surface area.
Can the foundation handle the extra (drag) forces involved?
The answers to these questions depend on the type of aquaculture (mussel,
seaweed, fish) and corresponding constructions, and on the specific turbine foundation (i.e. monopile, jacket or gravity based). Therefore, the scenarios are presented in matrix tables. The two different scenarios and their possible risks are
described below.
