Scope of work
iPipe Services was engaged to work on an abandonment project across four pipelines that had added problems around road crossings.
Highlights and results
iPipe Services successfully completed the abandonment of the four pipelines. We overcame a number of challenges and our solutions resulted in reducing the total cost to our client.
- The project included the use of LokRing technology as part of the abandonment process which meant there was no need for a carbon steel pipeline welder. This resulted in reduced cost to the client.
- The pipelines were not initially designed for pigging operations, so our team set up suitable facilities. Once set up, hydro-carbons and surplus fluids were removed using foam-density pigs and propelled through the pipelines with nitrogen.
- The age of the pipeline presented a challenge, as there was no accurate As-Built-Data available from the 1960s. To ensure we abandoned the correct pipelines, additional time for pot holing and line identification was required.
- Pigs, launcher and receiver supply (utilising LokRing)
- Transport and disposal of waste fluid
- Civil works including;
- Line location
- Pot holing
- Removal and disposal of risers, signage and cathodic protection units
- Plug, grout and abandon under rail crossings and roads
