Realtime detection of wax, asphaltene and hydrate accumulation in pipelines

Request Number N680315
Need details

Realtime detection of the contents of subsea pipelines, allows for the early remediation of issues. Once a pipeline has lost communication between its end, the use of pigs is not possible to clear the line. Inorder to remediate the problem, the extent of the problem needs to be understood including its location.
If blockages cannot be cleared then the pipeline will be abandoned, however regulatory requirements require that for a pipeline to be abandoned in place, the pipeline must be cleaned. Localised cleaning and removal of contents is required.
Detection of change in wax / hydrate levels, at the greatest speed possible. 




Existing pipelines and soon to be implemented pipelines are expected to have a lifetime of upto 40years and whilst future technology is based around integration of smart sensors into new pipelines networks, Subsea7 are also interested in addressing existing and short term needs around pipeline inspection.


Key Success Criteria
Non-intrusively detect the location of deposition build up quickly without interrupting production
Real-time data on flow profiles
Monitor changes in deposition for an enhanced understanding of remediation efforts.
Track the flow regime at specific reference points along the pipeline
Quickly identify flow assurance issues that may need further investigation
Quickly and non-intrusively locate any lost or stuck pigs
Technology has the ability to be used at / or developed to water depths from 0-3000m


Possible Approaches
System that can measure deposits from a range of 1-2metres above the pipeline even when buried
Able to be maintained and operated independent of development company
Able to work without the need for coating removal
Can operate on  a piggy back pipeline configuration
Can operate at high speed (1km/hr +)
Can also detect corrosion and wall loss



Approaches not of interest

Requires contact with the pipeline or extensive excavation of the pipeline.
