Subsea power hub

Electrify offshore facilities with power from wind farms or the onshore grid. Tucked away safely, under the sea.

Smart decarbonization for offshore assets
Our subsea power hub transforms power from shore, from offshore wind or both to decarbonize offshore facilities when space is tight. Placing it on the seabed, away from the topside yet close to the point of need, enables high-voltage transmission with reduced losses. 
Powering flexibility offshore
Based on proven subsea transformer technology, our power hub is scalable and can suit various offshore power requirements, making it easy to integrate alternative energy sources. Its core benefits are: no topside space required, free cooling provided by ambient seawater, a maintenance-free life under the sea for decades.

Integrating diversity

Subsea power hub technology can be used to meet a variety of requirements and scenarios of an evolving offshore power grid. Whether it’s flexibly electrifying offshore oil & gas facilities or connecting diverse sets of power sources and users:

  • Voltage step-down of power from shore to offshore facility 
  • Voltage step-down of power from offshore wind farms to offshore facility
  • Voltage step-down of power from multiple sources to offshore facility
  • Voltage step-up for electricity export
