Decommissioning Insight 2015

7.5.1 Central and Northern North Sea/West of Shetland Between 2015 and 2024, 492,200 tonnes are forecast to come onshore from these regions, an increase of over 130,000 tonnes on the 2014 report. Around two-thirds of this is due to new projects and the remainder comes from more detailed forecasts for existing projects. In line with topside and substructure removal, onshore recycling and disposal is forecast to take place across the decade (see Figure 26). There are high activity levels later in the timeframe, with a peak in 2023 at nearly 95,000 tonnes. The annual average over the next decade is 50,000 tonnes.
