Offshore substations are essential components of offshore wind farms. They serve as the central hub for collecting electricity generated by wind turbines and transmitting it to the onshore grid. The turbines are connected to the substation via subsea cables. Within the substation, the voltage of the electricity is stepped up to a higher level using transformers. This increased voltage reduces energy loss during transmission over long distances to shore.

These structures are typically located several kilometers offshore, in areas with strong winds suitable for wind turbine operation. The design and construction of offshore substations are complex, requiring specialized engineering and marine operations. They must be robust enough to withstand harsh environmental conditions, including strong currents, waves, and wind. They also need to be accessible for maintenance and repair.

The process of installing an offshore substation involves transporting the assembled platform to its location and then carefully lifting and securing it onto a foundation, which can be a jacket structure or a monopile. The electrical equipment, including transformers and switchgear, is then installed and commissioned. Offshore substations play a crucial role in the efficient and reliable operation of offshore wind energy, enabling the integration of renewable power into national electricity grids.
