Subsea smart hubs for floating wind

Subsea Smart Hubs (SSH) Joint Industry Project has been initiated with the aim of addressing new Inter-Array Cable (IAC) system architectures for floating wind farms. Subsea hubs allow Fishbone and Star architectures, that diverge from the traditional daisy-chain configuration with the potential to lower overall costs over the life of field, enhance availability and higher capacity factors resulting in a lower Levelized Cost of Energy (LCoE).

In order to precisely estimate potential cost savings, the study is based on different scenarios that will be detailed. A number of scenarios are chosen encompassing several possible farms layouts as foreseen by developers for the near future (66kV or 132kV IAC system, 500MW or 1GW wind farm, medium or deep water). A comparison of 3 different IAC architectures is performed: Daisy-chain (without subsea hub), Fishbone and Star configurations. This enables to identify floating wind farm configurations most susceptible to take advantage of subsea hub technology.
