OGTC Platform Power Hubs

Challenge

• OGTC Decommissioning Life Support Systems
• Call for ideas on Life Support Systems – ‘Power’

Current Issue

• Platforms powered by diesel generators or gas turbines using produced gas
• Powering diesel engines or gas turbines to run their machinery is inefficient from financial (Ops & Maintenance) and environmental reasons
• During Late Life, Cessation of Production and Decommissioning activities (i.e.: well plug and abandonment etc.) significant power generation required
• Increasing Operations, Inspection & Maintenance costs at a time where revenue stream from the facility may be dwindling

Opportunity

Reduce cost

• Efficiency
• Operation & Maintenance
• Import Cheaper Power
• Reduce Power outages

Reduce Environmental Impact

• Efficient Power Supply from Power Hub
• Cleaner Power from National Grid
• Avoid temporary Power Packages
• Use existing technology, techniques and infrastructure

Solution – ‘Power Hubs’

• Establish ‘Platform Power Hubs’
• Power Hub will be able to generate sufficient power to support a number of in-field satellite assets
• Power Hubs can be daisy-chained back to onshore power grid – using existing Windfarm substation supply connection
• Reliable Power Source
• Cleaner Power
• Potential Revenue Stream for Offshore Wind infrastructure

O&G Host Facility

• Reduces the OPEX cost for power generation for aging O&G platforms, especially as availability of fuel gas becomes restricted
• Allows O&G platforms to cut CO2 emission and meet offshore targets
• Reduces ABEX cost of O&G platforms as opportunity to decommission power generating plant / fuelling system pre-CoP
• Affords opportunity for O&G Host Facility to export power to satellite platforms – potentially opening revenue stream in late life
• Potential to incorporate data & comms link in power cable to allow opportunity for remote monitoring, inspection and control from onshore
• Provides surety of power supply, reducing trips on ageing generators, reducing impact on production losses
