In 2018 Subsea Innovation developed a next-generation seal for their Pipe in Pipe Waterstops. Waterstop Seals provide a solution for isolating a section of flooded annulus in offshore risers or flowlines by preventing water passage to the adjacent Pipe-In-Pipe sections during installation and normal operation. The new design addresses potential challenges experienced with High Frequency Welded (HFW) pipes and seam welded pipes being introduced within the industry as part of cost-saving measures.

Subsea Innovation are one of the only suppliers in the world to have successfully tested Waterstop seals with a proven recorded on HFW and seam welded pipes. HFW or seam welded pipes often require localised polishing to improve the sealing ability; whereas Subsea Innovation's next-generation SIStop® Waterstop Seal eliminates the need for this, sealing on pipes with greater surface defects and impurities.
The contract win demonstrates the global demand for the next-generation seal.
The product was designed and developed from Subsea Innovation's head office in Darlington.
Dave Thompson, Managing Director of Subsea Innovation, said: "Norway is a major market for us. Winning this project is recognition of the hard work of the team who develop equipment for the world's most challenging environments for the world's biggest customers."
