Offshore Wind Accelerator: Groundwater Effects

Call for entries from companies and consortia interested to undertake a study for the OWA Cables Technical Working Group (TWG-C) to investigate groundwater effects and establish a standard mechanism for assessing if groundwater effects are present and how they can be represented during thermal modelling for offshore cable design.

The main objectives of this project are to provide a recommendation of how the presence, and resulting benefits, of groundwater movement can be assessed at the different stages during cable design for offshore windfarms. Furthermore, this project aims to assess if increased rating capacity is available at typical export cable pinch points due to groundwater effects. Overall, the project aims to produce guidance for how to include, and justify, groundwater effects at deep onshore burials and landfall, for offshore cable design and thermal modelling.
