Decommissioning Insight 2019


On a regional basis, decommissioning spend is split fairly evenly between the CNS, NNS and SNS/IS in the immediate future. However, by the end of the decade, decommissioning in the CNS is rising to make up more than 50 per cent of total activity as expenditure in the NNS begins to decline. Activity in the west of Shetland and east Irish Sea is also seen to grow towards the end of the decade. The step change in regional forecast expenditure in comparison with previous years may be in part due to the amount of M&A activity which has recently taken place. Figure 8 details the M&A activity in the past two years where operatorship of an asset has changed. This shows that the majority of the assets which have been acquired are situated in the CNS, inferring that new owners plan to inject a new lease of life into these assets and ensure that dates for CoP are pushed to the right.
