Siteworks case study - gas upgrade

Siteworks case study - gas upgrade

National Grid Metering developed an engineering solution to ensure the gas could stay live during upgrade

When a major manufacturer in London needed to upgrade their vital gas supply, the Service Delivery team at National Grid Metering stepped up to design, build and commission a solution whilst keeping the site operational.

The site provided several obstacles, but key was that the factory needed to stay operational 24/7.

Senior Integrity Engineer, Mark Tarran, developed a solution that would allow the work to be complete with no interruption to the gas supply.

Another part of the scope was to reduce the risk to the asset by removing a 25 meter high, 36 inch diameter vent stack that was adjacent to the main loading entrance for the factory. This was then redesigned and the new design created a 50% reduction in the gas footprint within the compound.

All remaining original pipework had pipe supports replaced, grit blasted and painted to T/SP/PA/10 (four coat system) to futureproof the installation.

Mark Tarran said of the project

After identifying the problems with our client, we designed a solution that delivered what they wanted, within a timeframe acceptable to all.  Despite the coronavirus lockdown occurring in the middle of the job which postponed activity at site for several weeks, we still managed to commission the new install in June.

Through it all we maintained the gas supply to site allowing them to continue operating with minimal inconvenience, whilst National Grid Metering and our service partner Allgas1 delivered a complex project and overcame significant obstacles.
