Project Details
GMC Utilities Group recently used Denso Bore-Wrap™ supplied by Winn and Coales (Denso) Ltd on sections of a 2.7km gas pipeline which was being constructed to provide Gas to Kilroot Power Station which is situated on the north shore of Belfast Lough.
The contract secured by GMC with their JV partner Rayden Engineering was part of a £600m scheme to transform the coal fired power station into a new low carbon energy park. The 2.7km welded steel pipeline from Marshallstown AGI to Kilroot AGI was mainly installed by open cut methods, but at road crossings including one on the A2, the pipe was installed by HDD.
To ensure that the integrity of the anti-corrosion coatings on the pipe was maintained, GMCR Project Manager, Richard Kyle had Denso Bore-Wrap™ applied to these sections prior to pulling the pipe under the roadways.
Denso Bore-Wrap™ is an Abrasion Resistant Outerwrap (ARO) which has outstanding performance against impact, gouge, abrasion, and fracture. Bore-Wrap creates a superior sacrificial outer laminate layer, which protects both pre-approved fi eld joint coatings and mainline coatings (such as, liquid epoxy coatings, heat shrink sleeves, 3LPE, 3LPP and FBE coatings) from damage during pipeline installations, in difficult terrain or by means of trenchless installation methods, such as directional drilling, HDD or boring.
Denso Bore-Wrap™ is easily applied in the field; there is no mixing required, it is simply wrapped over the existing pipeline coating and cured with water. Due to its flexibility and exceptional level of mechanical protection, Bore-Wrap™ minimises the need for costly spot repairs or re-pulling pipes due to damage.

Denso Bore-Wrap™ is applied spirally with a 55% overlap to the pipe, followed by the application of Denso Polywrap™ to aid curing of the Bore-Wrap™.
The Denso Bore-Wrap™ is applied to the pipe by applicators, then sprayed with water triggering the curing process that turns it into the abrasion resistant outerwrap
