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