Decommissioning Insight 2019

3.5 Ten-Year Regional Overview The central North Sea (CNS) remains the area with the majority of decommissioning expenditure over the next decade. However, the proportion of expenditure in the CNS has reduced significantly since last year’s Decommissioning Insight , from 48 per cent to 42 per cent and reflects an increase in the northern North Sea (NNS), southern North Sea (SNS) and Irish Sea (IS). The NNS now expects to see 32 per cent of overall expenditure, up from 30 per cent in last year’s forecast, while the SNS and IS together expect to see 22 per cent, up from 15 per cent last year. The west of Shetland region has seen a slight reduction, down from 7 per cent of total spend in last year’s dataset, to 4 per cent this year, reflecting the future prospectivity of the region.
