Hitachi ABB Power Grids has engineered transformer products for offshore floating applications, designed to overcome the challenging offshore environment and withstand the physically demanding conditions on floating structures. These systems will enable greater volumes of wind to be efficiently harvested and integrated into the global energy system, directly supporting the transition to a sustainable energy future.

Building offshore poses challenges beyond the harsh saltwater environment. So far, only a small fraction of offshore potential has been exploited, as in many areas the seabed is not suitable and depths of 60 m are Source: Hitachi ABB Power GridsSource: Hitachi ABB Power Gridsnot feasible for fixed structures.

Floating substations and floating wind turbines offer a solution, for deployment in deeper waters, vastly increasing the available global capacity for developing offshore wind energy. Yet floating systems come with their own challenges: over their entire lifetime they are constantly in motion and can be exposed to vibrations and shocks from waves up to 15 m in height.

The new range includes collector step-up transformers, earthing transformers and shunt reactors for floating substations plus wind turbine transformers for floating wind turbines, including the industry leading WindSTAR units.

Transformers and shunt reactors are key components in the grid infrastructure, enabling transmission of electricity generated by offshore windfarms. This complete and qualified equipment range, developed in partnership with leading floating offshore developers, meets challenging operating requirements with a lightweight and modular design made up of specially designed active part, tank, tap changer, accessories and external components.
