Nexen Hires Pipetech for Scott Platform Job

Pipetech, the independent process system integrity specialist, has won a project with operator Nexen to deliver active caisson management on its Scott platform.

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

Eric Doyle, managing director at Pipetech said: “By carrying out the work while the platform remained in operation, we saved the valuable cost implications of shutting down production as well as a lengthy start up process.

“Our Active Caisson Management service means we will continue to manage inspection on the Scott platform to monitor the caisson’s internal scale levels and intervene if required.”

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 Aqua Milling technology was deployed 27 meters above sea level and recovered back to the 1.5 inch 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.
