The UKCS decommissioning challenge is significant. It will be expensive and span several decades.

It must be carried out safely and with care to protect the environment. However decommissioning presents significant opportunities for innovation, cost reduction and development of UK skills and capability.

Estimates of scope, complexity and cost vary but there are over 320 fixed installations, over 3,000,000 tonnes of structure, over 75,000 tonnes of subsea structures, over 20,000km of pipeline and approximately 4,000 wells, all of which must be decommissioned or re-used.

In accordance with the principles of MER UK, and whilst supporting the drive to net zero carbon by 2050, there is a need to significantly reduce decommissioning costs through increased efficiency and, more importantly, industry transformation.

Our Decommissioning Strategy summarises current cost projections, outlines efficiency improvements and transformative options that will support the delivery of MER UK, whilst supporting the drive to net zero carbon by 2050, and sets out three clear priorities. The 2016 Decommissioning Strategy and Delivery Plan is under review and a refresh by OGA with Industry is ongoing.

  • 1. Cost certainty and reduction

    Driving targeted cost efficiency programmes including innovative and regional approaches with extensive and effective knowledge sharing and best practice adoption.

  • 2. Decommissioning delivery capability

    Developing an efficient and exportable low-cost and profitable decommissioning delivery capability supported by a competent and efficient supply chain, a selection of business execution models, all designed to appropriately allocate risks, align industry participants and drive down costs.

  • 3. Decommissioning scope, guidance and stakeholder support

    Working with BEIS and other relevant parties to identify and evaluate opportunities to further optimise and define parameters for decommissioning scope and improve industry engagement with the regulators.
