Oil & Gas UK Decommissioning Insight 2014

Southern North Sea and Irish Sea

1

The number of topside modules per facility is significantly lower in the SNS and IS areas than the CNS and NNS due to the large proportion of small satellite installations and NUIs. Their smaller size means that both ‘making safe’ and topside preparation can be carried out in a single year. This is reflected in Figure 11 where the two activities are closely aligned. Activity is forecast to peak in 2019 at 24 topside modules on 12 installations. The peak in activity occurs one year prior to the peak in removal activity discussed in section 6.3.
