In May 2016 Pipetech were delivering a range of topside cleaning solutions on Snorre B fpv under a frame agreement with a major Operator.
We were approach at the time and asked if we could take our methods in to the subsea environment, to help with a scale blockage in a subsea water injection manifold, 380 meters below the platform.
Previous attempts had been made to clear the blockage with chemical runs and pigging, these methods had failed to clear the blockage and the customer had started to prepare to shut down the field and pull the manifold.
In response, we took our experience in cleaning pipeline and process system blockages, with high pressure water and designed the DWCS, a bespoke subsea deployed solution.
The customer liked the design and gave the go ahead to build.
Project Manager, Pipetech:
"The Deep Water Cleaning System (DWCS) enables Pipetech to complete cleaning operations in subsea manifolds, trees and pipelines in a fraction of the time it normally takes with conventional methods."
