The project

The project brief required extensive interfacing between the client and the multiple sub-contracted vendor packages to ensure the delivery of an integrated and successful design. In addition, the project required coordination with National Grid who were building a new Above Ground Installation (AGI) adjacent to the project site, designed to feed the new SGN Offtake.

Key site components included:

  • Inlet Remotely Operated Valve (ROV) – Specification and interface design to Gas Control Centre
  • Volumetric Control – Twin Stream Volumetric regulator control
  • Gas Pre-Heat – Integration of new Heat Exchangers and Boilerhouse
  • Gas Conditioning – Integration of new odorant injection facility including local storage tank into site layout and systems
  • FWACV Ultrasonic Metering – Twin 12″ ultrasonic metering installation with full FWACV
  • High Pressure Pipeline – design of approx. 1.5km of HP main to connect the plant outlet to a new multi-junction site.
  • Broadsea Multi-Junction Site – Design of new multi-junction site with pig trap facility to connect new Burnhervie Offtake to reinforce existing Northern HP network.

The pipeline presented a number of challenges, not least the fact that there was a fall in excess of 60m from the Burnhervie offtake to Broadsea multi-junction.  The project was delivered quickly, safely and in line with the original scope and programme.
