National Grid Milford Haven

Client National Grid Gas

This £1bn project involved the construction of a 300km pipeline from Milford Haven in West Wales to Gloucestershire. The pipeline can carry a fifth of the natural gas required by the UK. Our teams provided full project services on 2 of the pipeline’s major sections in South Wales - Aberdulais (120km) and Felindre to Brecon (80km). As a business, we have an extensive and specific knowledge relating to the design and construction management of Above Ground Installations (AGIs), having previously managed National Grid AGI’s within South Hook LNG (named Herbrandston) and Dragon LNG (named Newton Noyes). 

During the lifecycle of this project, our teams provided design co-ordinators, project managers, project supervisors, construction managers, construction engineers, quantity surveyors, land agents, ALOs, document controllers, health and safety managers, environmental managers, and archaeologists. 

We applied design, safety and engineering principles to the construction of the all the AGI’s whilst meeting the client requirements in terms of specification, budget and timescales. This was a particular challenge as the time constraints were exceptionally tight, exacerbated by the associated planning issues that placed significant challenges on the team to ensure the receipt of planning approval. The project team on site had to maintain control of the construction team, allowing progress to be made and implementing design changes in line with the client requirements. 

As construction neared completion, we provided the team to manage commissioning of the sites together with the testing and commissioning of the connecting pipeline. The MWC and REI project teams worked closely to deliver the AGIs and connecting pipeline within the time window and to the required standards specified by the client.
