• Around 25 kilometres of pipeline are forecast to be decommissioned in 2016, rising to an average of over 300 kilometres per year between 2018 and 2022.

• Activity is expected to peak at over 1,000 kilometres in 2024.

3

• The majority of this activity involves inter-field pipelines connecting fields to host facilities, although some import/export lines are included.

4

• Pipeline decommissioning activity is one of the later activities in a decommissioning project and there is therefore a high degree of uncertainty in the timing.
