Supergrip deliver ROV Activated J-Tube Seal for bundle assembly

Supergrip have successfully completed the delivery of an ROV Activated J-Tube Seal to suit a 6” NS umbilical together with a 4” NS MEG line.

Gordon Conlon, Director at Supergrip, said “This has been a really interesting and challenging project for our team to work on. I’ve been involved in the design of J-Tube Seals for in excess of 25 years and this assembly has the most modules incorporated into any system I’ve seen. The system was designed to accommodate a bundle arrangement and tested to 16 bar.g differential pressure. We included features such as: J-Tube latching mechanism; pressure verification facility; an ROV releaseable clamp arrangement accessible from two locations to accommodate for potential rotation during deployment; as well as a range of assembly tools to assist with the vertical installation onboard the vessel. In addition, we also supplied 15m of the patented Fast-Lok boltless bend restrictor to suit the bundle arrangement”

Johnny Molloy, Senior Project Engineer at Supergrip, stated “This has been an excellent long term project for us to be involved with. We have worked successfully alongside the cable manufacturer, the ROV installation contractor, as well as the operator. It was a really enjoyable process due to working closely alongside all the engineers from the different parties as addressing the project challenges. Our team in Colne performed a testing process, over an intensive three day period, which included a simulation of the vertical installation as well as ROV activation of the equipment within the bellmouth. We are pleased to say that all modules functioned as planned. I’d like to thank all parties involved in the project as well as our production team for the level of commitment shown.”
