Aqua Milling 6″ Degasser Outfall Line

Pipetech mobilised to Judy to unblock a 6” outfall line which could not be reached by conventional methods due to the pipework length and bend configuration.

Using Aqua Milling® specialist nozzles and rotational hose, Pipetech negotiated 8 bends to 64 metre reach at 950Barg working pressure.

Time constrained to remove a blockage at 40m within a 64m degasser outfall line utilising only one access point on main deck negotiating one bend prior to entering system.

• Pipetech ensured the line was completely blockage-free successfully completing ahead of scheduled duration.
• Fully removed a substantial blockage and cleaned to a higher standard than previous traditional methods ensuring the line can return to operation for a longer period.
• Recognised reputation with new client providing enhanced service quality along with introducing new technology to provide the optimum unblocking solution with minimal impact on POB.

• Safety – Fully contained, remotely operated jetting system carried out cleaning within a controlled area on main platform deck without the need to expose personnel to high risk underdeck working.
• Cost Saving– Aqua Milling® capability over traditional cleaning methods eliminated need to break into the line for additional access. Previous mobilisations using traditional cleaning methods required a rope access team, over board personnel watch and underdeck scaffold.
