This report, commissioned by Oil & Gas UK and Decom North Sea, and produced by Arup, seeks to identify the barriers and challenges to adoption of novel solutions in the oil and gas offshore decommissioning industry. It sets out a process for the commercialisation of novel solutions to accelerate cost reduction in decommissioning and identifies issues specific to each phase. Finally, it seeks to address how to overcome these barriers and challenges to encourage more rapid innovation in the market by making a number of recommendations to industry and government. These recommendations, as presented by Arup, lay out possible areas of focus for various stakeholders, to support a culture of innovation in the decommissioning market. Oil & Gas UK and DNS will consider the recommendations and engage with the relevant bodies to act upon them, as appropriate.
