Protection of Submerged Gas Pipeline Calls for the SeaShield 70 / 80™ System
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 and primer , a tough PVC-backed bitumen tape , and a glass-fibre reinforced outerwrap ; all of which combine to form a robust protective coating with exceptional impact and mechanical strength .
Work was undertaken by the Pipeline Maintenance Centre on behalf of Cadent Gas , with products supplied by Lynvale Ltd .
Winn & Coales ( Denso ) Ltd are leading manufacturers and suppliers of corrosion prevention and sealing systems . Their SeaShield systems have offered comprehensive corrosion control on jetty piles and marine structures for the last 50 years .
