Flagship Transfer Project
Developing special structures for offshore wind power: Offshore electrical power substations
Dolwin 4 and Borwin 4 were the projects consolidating IHCantabria’s relationship with Dragados Offshore in 2023. These are two 900MW-power substations that are expected to be connected to the electrical grid in 2028 in German waters of the North Sea.
Challenge
Offshore wind power substations are critical structures for the proper operation of an offshore wind farm. IHCantabria stands out as one of the four European laboratories to analyse offshore wind structures and it is currently the only one to develop large scale assessments to minimize the effects scour on structures’ foundations.
Solution
Designing and assessing the Dolwin and Borwin 4 scour protections. Thisexperimental work adds to previous experiences of IHCantabria on the assessment of scour impacts on offshore wind bottom-fixed designs.
Results
Using advanced techniques and scaled models, IHCantabria managed to create a protection solution that is compatible with a highly-complex structure such as a jacket-type offshore power substation, designed to withstand extreme currents and waves such as those in the North Sea.
