Supergrip have successfully completed the supply of a pipeline repair system designed to provide end of life protection to a redundant pipeline branch connection.
The bespoke equipment was designed to ASME VIII Div 2 to suit a 24” NS pipeline with a pressure rating 100 bar.g. As well as providing a fully sealed cavity the grouting ports were included for branch strengthening if required.
An offshore survey of the platform location was performed prior to production including the trial installation of a replica template. The project was completed on a 24 week schedule which included an extensive qualification testing period.
Sheldon Jeffrey, project manager at Supergrip, said “This project provides a good example of our design capability to address challenging pipeline repair applications and is also evidence of the benefit of our comprehensive in-house manufacturing and testing processes.
The contract offered a number of challenging aspects not least was the closeness of the surrounding pipework meaning that the assembly had to be of a modular construction to enable installation into the difficult location. The branch to be protected was actually the centre one of three. However due to access limitations it was decided to provide an assembly that covered all three redundant lines.
I must pay credit to our production team who subjected the equipment to a thorough testing process over many weeks which gave us the opportunity to fine tune aspects of the design. This was the second project that we have successfully worked on with our client, the prevoious being a subsea pipeline repair, and our relationship goes from strength to strength.”
