James Fisher Decommissioning February 2022 Testing



James Fisher Decommissioning (JF Decom) needed to be able to test and demonstrate their innovative internal abrasive water jet cutting tool in a controlled and safe water environment. The scope of the trial was an internal cut of a test piece measuring 1895 OD x 6000mm length. 



JFD was able to host the test and demonstrate at its National Hyperbaric Centre in Aberdeen, using the 900,000 litre steel dive tank, yard and office facilities.

In advance of the test and demonstration, JFD technicians drained the test tank and installed underwater cameras inside, enabling JF Decom to film their tool cutting the test piece of pipe underwater.

JFD set up the boardroom onsite, which overlooks the dive tank, for JF Decom and their clients to use during the trial. This included a live feed from the underwater cameras displayed to the screen in the boardroom so they could view the demonstration in real time.

A crane was hired to support the lifting of the tool and equipment in and out of the tank during both the dummy run and live demonstration.

JF Decom used the yard beside the tank not only for their equipment, which was supporting the test, but also as a lay down area for the cut pipe to demonstrate the effectiveness of the tool to the client.



The test and demonstration was very successful and a 360° cut was achieved in 3 hours and 50 minutes. JF Decom was able to exhibit the effectiveness of their tool in one location both safely and efficiently.

JF Decom’s clients were able to witness in real time how the tool worked and see up close the end result of the cutting technology.
