DE-COMMISSIONING SERVICES
When process plants and pipelines reach the end of their useful life or become redundant, it is necessary to de-commission them to make safe for demolition or for mothballing for potential further use or change of duty.
The de-commissioning process will depend on previous use and future requirements. Our Team can assist in the planning and de-commissioning services.

Decommissioning programmes will comprise some or all the below:

For pipelines
Initial pigging to remove bulk product (using nitrogen if product is hydrocarbon based or flammable).
• Cleaning, mechanical (pigging) and/or chemical to remove residual products.
• Drying & inerting with nitrogen to prevent further deterioration.
• Inhibitors (vapour phase types) for systems requiring mothballing.
• Removal and storage of pumps/compressors etc.
• Scrapping the line or fill with fly ash / cement.

For process plants:
• Removal of bulk hazardous / flammable liquids and vapours using nitrogen.
• Chemical and / or mechanical cleaning to remove residual products.
• Remove pumps / compressors, reusable items for storage, re-sale.
• Scrap unusable equipment.
• For mothballing: dry, inert & inhibit to prevent further deterioration.
