SGN are now looking to develop improved PRS designs based on the Oxford Flow Regulator and associated technologies for pressure reduction from 7Bar to 2bar. The project is broken down into work packages with each package requiring the production of a report for approval by SGN.

An independent Technical Services Provider has also been appointed to provide technical review of key aspects of the project and assist with production of technical documents and procedures.

WP1: Test regulator with current Pressure Reduction Sled

  • General design for fitting and instrumentation

  • Specification of main components including regulator

  • Assemble regulator, sled and configure

  • Test regulator on rig in laboratory

  • Model performance and scale

WP2: Customer scope and specification, concept design

  • Review standards, scope and general needs

  • Site visits investigation and Initial definition of site for field trial

  • Market and international needs

  • Define specification for the sled

  • Complete concept layout and initial performance modelling

WP3: Development of regulator and silencer package (7 to 2 bar)

  • Define spec and complete concept design

  • CFD, FEA, mathematical and other modelling: virtual prototype

  • Commission prototype components

  • Assemble and test in laboratory

WP4: Development of filter

  • Define spec and concept design: Design approval.

  • CFD, FEA, mathematical and other modelling. Virtual prototype

  • Commission prototype components

  • Assemble, instrument and test in laboratory

  • Final design drawings for other size ranges for different skid applications

WP5: Development of pilot

  • Define spec and concept design: Design approval.

  • CFD, FEA, mathematical and other modelling. Virtual prototype

  • Commission prototype components

  • Assemble, instrument and test in laboratory

WP6: Communications package

  • Specification, integration, commission and test

WP7: Element Procurement

  • Identify contractors (prototype and volume)

  • Costings

WP8: Detailed design of PRS

  • Review elements, customer need, sites, scope

  • Complete layout design. Design approval.

  • Identify client sites

  • Full sled costing

  • Plinth and acoustic housing specification / sourcing

WP9: Live field trial - individual elements of PRS

  • Extended test of regulator - parallel in stream (was task 1.10)

  • Scope and set-up trials

  • Regulator and silencer (and pilot) field trial

  • Filter field trial

WP10: Live field trial - full PRS

  • Commission, assemble

  • Field trial

  • Skid modifications if required

WP11: Pressure Reduction Station of the Future

  • Research, conceptual design, initial performance estimate

The objectives of the project are to:

  • Develop a market-ready optimised PRS delivering significant improvements in whole life costs over current PRSs
  • Complete designs for an above ground, semi-submerged and below ground PRS
  • Test the Oxford Regulator in the field
  • Evaluate the fully optimised PRS in the field
The project will be deemed to have been a success if the following criteria have been met,

Testing and evaluation will be conducted offsite at the Oxford University flow test centre and on site during field trials.

  • The PRV, pilot and cyclonic filtration unit operates in the field continually over two seasons with no maintenance and control issues.

  • A notable reduction in noise levels is recorded when used with the silencer when compared to traditional PRS designs under high flow conditions.

  • Construction and whole life costs prove to be lower than the current traditional PRS designs

  • The PRS of the future conceptual study is evaluated by SGN and TSP and considered viable.
