Supergrip are pleased to announce that they have recently completed the supply of a 14” NS bespoke pipeline repair clamp designed to suit a subsea flanged connection.

The clamp was designed with an internal cavity to bridge the flange connection and rated to ANSI-600. In addition to the clamp itself, Supergrip also supplied a diver installation frame that would be removed subsea.

Sheldon Jeffrey, operations manager for Supergrip, said, “This was another example of our capability to respond to fast track projects. This particular clamp and installation tool was produced and installed within a 15-week schedule. The benefit we had on this project is that it was a repeat of a system we installed in 2017, therefore we were able to remove the engineering activity from the scope. As with all of our products we place great store on workshop testing. This clamp was again subjected to a full Factory Acceptance Test, which was streamed by video conferencing to the installation contractor and our client. This has the benefit of involving all personnel and enables offshore experience to be included in the finished product.”

Joe Griffiths, Supergrip’s project engineer, who supervised the installation onboard the vessel said, “This was a great experience for me to work with an excellent team offshore. We boarded the vessel on Wednesday and during transit to site we performed pre-dive verifications. Installation commenced Friday evening and by Saturday afternoon the divers had successfully installed and the clamp, subjected it to pressure verification tests, and removed the installation tool. During the initial survey, I also got to see the original clamp installed three years previous, still functioning as intended.”
