Flow assurance monitoring

Ashtead Technology have an extensive array of packaged solutions covering a range of flow assurance monitoring applications.

Managing flow assurance on subsea production assets has to take into account the potential for solids build-up, which could cause a partial or full blockage within the flow stream. While flow assurance measures may be in place to mitigate and prevent solids deposition along the flow-stream, in some circumstances, these may not fully protect the subsea system and wax, scale or gas hydrate may cause problems.

In-line inspection, outside line external inspection and pigging can all be deployed to detect, locate and quantify issues, but these require the support of subsea monitoring and sensing systems.

Ashtead Technology can deploy its extensive knowledge of pipeline sensing and pig location technologies to support flow assurance requirements, providing vital early information allowing timely intervention to mitigate or reduce the impact of pipeline intervention.

Rapid and reliable blockage location and remediation of a partial or full blockage is an essential requirement to support production flow assurance and avoid lost production.

Ashtead Technology has in-house expertise in providing solutions to support the location of pipeline blockages externally through the pipe-wall using radiography and acoustic based technologies.

We can deploy our knowledge and experience of through-wall pipeline solids deposition to both locate and estimate the extent of the build-up, allowing rapid response to production issues, reducing production losses.

When running in-line inspection and pigging tools, there is a potential for the pig to become stuck due to an obstruction or pipe damage. Rapid location of the in-line tool and establishing the likely cause of it being stuck are important and require pre-planning, particularly when the pipeline has been in service for some time and where solids build-up is anticipated.

Ashtead Technology are able to provide solutions to support the location of pipeline cleaning and inspection pigs utilising radiography, acoustic and electromagnetic pig location techniques.

With our knowledge of through-pipe location and measurement techniques Ashtead Technology can provide contingency support systems for pipeline cleaning and inspection operations which are optimised for the diameter, wall thickness and expected conditions. This allows for rapid response and clear information to be acquired in the event of an unplanned issue.
