Pipetech Wins Caisson Management Contract from Nexen

Pipetech, the independent process system integrity specialist, has won a project with operator Nexen to deliver Active Caisson Management on its Scott platform.

Active Caisson Management delivers a single sourced solution for inspection, cleaning, coating and planned and programmed maintenance and repair scheduling to drive cost efficiencies and maintain asset integrity throughout the lifecycle of a caisson.

Pipetech has successfully completed the first stage to remove internal scale build up from a 42-in. produced water caisson on the platform, 188 km from Aberdeen, while it remained in operation. The scope also includes ongoing inspection and monitoring.

Following a site survey to identify the full requirements, Pipetech deployed a team of four to carry out the clean utilising its Aqua Milling technology. The system has a proven track record in successfully removing the toughest of scale and blockages which other systems struggle with and has the ability to reach up to 600 m in a straight line from a single point of entry. It can negotiate up to 20 directional changes. Pipetech is currently the only company licensed to use Aqua Milling in the UK.

The Aqua Milling technology was deployed 27 m above sea level and recovered back to the 1.5-in. entry point, mitigating any chance of blockages. In total, the project took eight days to complete with a full camera inspection conducted during a planned outage to further confirm the results of the cleaning.
