timeframe
DECOMMISSIONING PHASE
12. • Prepare a detailed Decommissioning Plan, laying out the:
- Decommissioning objectives;
- Decommissioning procedures;
- Environmental and social implications of
decommissioning;
- Implementation strategy, including stakeholder
engagement; and
- Waste management, including opportunities to reuse or
recycle material.
13. • Identify areas where subsidence of an abandoned pipeline
cannot be tolerated (e.g. infrastructure crossings) and might
require filling the pipeline with an inert material to prevent
subsidence.
Pipe cleaning 14. • Notify relevant authorities and adjacent land owners before
decommissioning activities commence.
Waste
management and
pollution
remediation
15. • Vent and clean the pipeline that is to be decommissioned to
prevent future leakage of hydrocarbons into the environment
or build-up of gases.
16. • Clean and purge all associated equipment before
disconnecting or removing it.
17. • Ensure that product removed from the pipeline during
decommissioning cleaning is used or disposed of
appropriately.
18. • Ensure that water (or any other substance used to clean the
pipe) is treated and tested for hydrocarbons before being
discharged or disposed of.
19. • Reuse and, if that is not possible, recycle as much of the
removed material as possible. Disposal of material should be
a last resort, and done so as to prevent pollution of the
environment.
Rehabilitation 20. • Rehabilitate areas where surface disturbance took place as
part of the pipeline decommissioning (e.g. through removal of
surface equipment or pipeline).
21. • Based on the investigations undertaken prior to
decommissioning, consider filling the pipeline with e.g.
cement slurry or other appropriate material to prevent
subsidence where appropriate.
Alternatively, consider maintaining the cathodic protection of
the pipeline to prevent corrosion and collapse thereof.
