A total solution for platform decommissioning
After more than 40 years in operation, the platforms at the Viking Field, 168 km East off the Lincolnshire coast, UK, had served their purpose: the operator recovered almost 125 billion m³ of natural gas over the course of the years.
Halliburton was appointed to decommission 9 satellite platforms and 3 subsea facilities and partnered up with Atlas Copco Rental to supply a full scope of air, power, nitrogen and service technicians.
A truly total solution
The decommissioning of these platforms was a whole undertaking: pipelines had to be isolated, depressurised, cleaned and removed.
No less than 7 TwinAir diesel-driven compressors fed 4 membrane nitrogen generators. Two more 350 kVA diesel generators and accessories complete the installation, which ran for a total of 800 hours over the course of 60 days. Six Atlas Copco Rental technicians travelled along to keep all the equipment in perfect working order.
The whole installation delivered nitrogen with a purity of 97% at 22 bar, the ideal recipe to clean a gas pipeline, also safely displace the wellborn fluids and to perform diagnostic tests. The compressed air was used to drive “pig trains”, large plugs that are launched in a controlled way through the pipeline to clean or flush it.
Atlas Copco Rental will be supporting Halliburton with other operations such as abandoning redundant wells and preparing pieces of the platform for heavy lifting.
