Project Details

Winn & Coales (Denso) Ltd.’s SeaShield 70/80 System was recently utilised during maintenance works on a National Grid pipeline in Cumbria.

Crossing the Duddon Estuary near Barrow-in-Furness, the existing anti-corrosion coating on the National Transmission System (NTA) pipeline had suffered mechanical damage due to shifting sand banks in the area. The remote location prohibited excavation machinery from accessing the site, requiring sections of the 10-inch diameter pipeline to be excavated by hand, thereby restricting the amount of pipe that could be accessed.

Once excavated, surface preparation was conducted to remove light marine growth and loose rust before the SeaShield 70/80 System was applied. Designed for the protection of submerged and shoreline pipelines, the system features water-displacing petrolatum tape (SeaShield Marine Piling Tape) and primer (Denso Paste S105), a tough PVC-backed bitumen tape (Densopol 80 Tape), and a glass-fibre reinforced outerwrap (Denso Glass Outerwrap); all of which combine to form a robust protective coating with exceptional impact and mechanical strength.
