Decommissioning / Passivation

Web - decomm

The passivation and preservation of pipeline systems is normally associated with the decommissioning and abandonment of installations and is normally performed by use of the following options; nitrogen, steam, water, ultra high pressure jetting or mechanical cleaning. Method selection is normally dependant on the system to be treated content and the pipe specification.

These processes will remove hydrocarbons, scale, mud, burnt oil and other residues found on internal surfaces and they will also remove marine growth and shellfish from external surfaces. Waste and effluent is collected and treated in accordance with current and specific environmental directives and are certified as free of hydrocarbons.

Onshore and offshore certified equipment is available from our wide range of stocks and include steam generators, nitrogen equipment and high pressure jetting units.

IKM Testing has extensive experience in the removal of hydrocarbons prior to shutdown and during decommissioning activities.
