Project Overview:
Dragon LNG conversion, Wales, 2007
The Dragon LNG site is being constructed in Milford Haven to enable the import and storage of Liquefied Natural Gas. Until 1997 the site was used as an oil refinery, as a result some areas of the site suffer from sub-surface hydrocarbon contamination. The conversion requires substantial electrical works and re-wiring. Traditional methods of using lead sheathing to provide hydrocarbon resistance are not acceptable due to it’s high environmental impact and cost in production of the cables.
The Challenge:
To work with MW Kellogg & Whessoe/Volker Stevin to specify and supply an environmentally friendly alternative to lead sheathing that will provide all the benefits of hydrocarbon resistance at a lower cost.
The Solution:
FSC allocated a project manager to visit MW Kellogg, a full review of the site drawings and wiring diagrams was conducted to understand the design issues, followed by a site visit to fully clarify the installation environment. From this information special cables were designed and manufactured with a composite Tri-Barrier system made from aluminium, HPDE and polyamide to provide Aliphatic & Aromatic hydrocarbon resistance.
The Tri-Barrier system is lighter weight and has reduced diameters compared to traditional lead sheathed cables reducing installation times and offering space saving.
Summary:
By working with MW Kellogg closely FSC were able to provide an ideal solution that was cost effective to produce without the common pollution issues associated with lead sheathed cables. Additionally, the cables were faster to install due to the reduced weight and size resulting in greater cost savings on the project.
