The North Sea Transition Authority (NSTA) published its Decommissioning Cost and Performance Report on 9 August 2023, showing that the cost estimate for decommissioning remaining oil and gas infrastructure on the UK Continental Shelf is £40 billion.

The North Sea Transition Authority is the competent authority for all onshore and offshore well activity including well decommissioning.

The North Sea Transition Authority is committed to ensuring the economic recovery of UK oil and gas and to enabling the achievement of the UK Government’s commitment to reach net zero emissions by 2050.

Repurposing offshore oil and gas infrastructure can reduce waste and accelerate energy transition.
