Kvasir Group used Roxtec TB (tank boundary) seals during the installation of an Ice Load Monitoring System onboard the UK Royal Navy's only icebreaker, HMS Protector, in UK Docks Teesside in Middlesborough. It was the only sealing solution that was certified to meet the high customer requirements for water-tightness and gas-tightness in the application.
UK Docks Marine Services North has been providing long-term support for the naval ship since April 2019. The HMS Protector has the demanding job of serving the UK’s interests in Antarctica. UK Docks appointed Kvasir Group to conduct modifications and upgrades with works being undertaken in UK Docks Teesside.
“We needed to pass single and multiple sensor cables through penetrations in tank boundary walls,” says Jeff Clark, Operations Director at Kvasir Group. “Roxtec helped us with seals and sleeves especially suited and certified for tank boundaries, and also by creating bespoke cores for the seals.”
Kvasir Group has a long-standing close relationship with cable sealing specialist Roxtec. As this was an installation of new equipment and also a new technical requirement, Kvasir Group approached its long-term partner to discuss the challenge. Roxtec UK responded quickly, and the technical and commercial support team at the Roxtec headquarters in Sweden was able to present a solution.
”Roxtec helped us with seals and sleeves especially suited and certified for tank boundaries.”
Post retrofit quality assurance
Roxtec TB seals with Roxtec SL TB sleeves, supplied together as a kit solution, were chosen by Kvasir Group, mainly because the solution was certified for the application and the sealing requirements. The seals were used for one opening with a single sensor cable, two openings with two sensor cables in each and one opening with six sensor cables. All cables had an outer diameter of 9.6mm. Roxtec representatives performed visual inspections after the cable seal installation work to ensure quality and safety, and supporting information was shared with classification society DNV.
