Deeside Project Awarded

« Go Back to 2008

Wales & West Utilities, formerly part of National Grid Transco, is a regulated gas distribution business with pipelines across Wales and southwest England. Its primary role, undertaken on behalf of gas shippers, is to transport gas safely and efficiently to the gas meters of homes and businesses.

Recognized as a leader in safety performance, Wales and West was chosen as Gas Industry Network Operator of the Year in 2008 and received the Customer Service Award in 2009.

Long O Donnell Associates was awarded the Deeside Project, this comprised of the diversion of an existing National Grid pipeline to accommodate the planned improvements to the Dunkirk Junction of the A5117 with the M56 north of Chester.

The existing National Grid Transmission 750mm Steel Mickle Trafford to Deeside (Feeder 21) high pressure pipeline runs directly under the existing A5117 carriageway and through the area identified for the planned improvements. Currently the 750mm pipeline has a maximum operating pressure (MOP) of 70 bar although it was designed and tested to operate at 75 bar.

The project involved replacing approximately 400m of the existing pipeline with a 450m diversion utilising 762mm pipe and Long O Donnell Associates have been requested to conduct the Commercial, CDM & HSE Management for the entire project.
