Supercritical Carbon Dioxide Flushing

Innovative method to clean umbillicals, control -and chemical injection lines

The Supercritical CO2 flushing system (SCCO2) fits perfect for control lines and umbilical’s, because of the low-pressure drop over long distances, which can exceed 20 km, with a small inner diameter lower than ¼”. This means that turbulent flow can be maintained all the way thru, and a cleanness of AS4059 Class 3 / ISO 4407 12/9 has made proof of concept in testing. However, it can also be fitted to other appliances.

Conventional flushing is a well-known method to clean to the inside of systems, and a turbulent flushing flow is mandatory for cleaning effectively. A challenge, when using conventional flushing fluid in systems like umbilicals and control lines, is the ability to keep a turbulent flow all the way through.

Complies with the following directives:

  • EC directive 2006/42/EC (Machinery directive)
  • EC directive 2014/34/EU (ATEX directive)
  • EC directive 2014/68/EU (PED directive)
  • EC directive 2014/30/EU (EMC directive)
  • NORSOK E-001
  • NORSOK I-001
  • NORSOK Z-015
