AC Solutions for offshore wind connections

Our AC solutions are designed for connections under water and underground over short and medium distances. More and larger wind farms are being located offshore. The capacity of these wind farms is of the order of several hundreds of MW. To minimize the electrical transmission losses and the cable costs, the turbines in such wind farms are electrically connected to an offshore substation provided with a step-up transformer. The transmission to shore is then achieved by an HV AC connection. 

Substructure design
The substructure design is typically a jacket and topside but it can also be a simple steel mono pile or it can be a self installing type. ABB can adopt to both local requirements and customer demands to provide a cost optimized solution for the total lifetime of the offshore wind farm. ABB has a track record on platforms with different substructure designs and can help the customers already during feasibility stage to select the best solution for their offshore wind project.
