Longer design life for offshore infrastructure

Our recent study [1] for The Crown Estate, analysing the costs and benefits of designing and operating offshore electricity transmission infrastructure for a longer lifespan is now available for download via the Marine Data Exchange.

The study compares the lifecycle of transmission assets at an offshore wind farm using a 30-year scenario and a longer-life 60-year scenario. The work explores the technical and economic feasibility of whether offshore transmission could be designed, operated and maintained for up to two offshore wind farm life cycles.

The results suggest that designing and operating offshore electricity transmission infrastructure for a longer lifespan has the potential to be more cost effective than current practice.
