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
