Platform Electrification Notional Concepts


Power from shore

  • Power supplied from onshore grid
  • HVDC transmission to hub
  • Hub substation/oil and gas platform
  • AC distribution from hub to platform

Power from windfarm

  • Power supplied from offshore windfarm (existing or new)
  • Excess output from windfarm exported to shore
  • Platforms draw power from shore if wind output insufficient
  • HVAC transmission to/from shore
  • AC distribution to platforms

Offshore microgrid

  • Power supplied from dedicated windfarm
  • No connection to shore
  • Power hub contains back-up generation and battery storage for continuous power
  • AC distribution to platforms

Standalone solution

  • Turbine(s) providing power direct to single platform
  • Partially electrifies operations
  • Back-up power uses traditional gas/diesel generators optimised to reduce emissions
