  1. Packaging bio-methane connections for the future Dan Anderson CEng 11th January 2012

  2. The context • Utility bespoke design and build delivery model needs to evolve for the growth of renewable gas connections – approximately 250 biomethane injection plants will be required by 2020 to meet UK renewable energy targets. • Current approach: • Design and build cost is circa £650k for the injection plant (excluding connecting pipe and remote monitoring). • Lead time circa 12 months design and build (excluding remote monitoring point and remote monitoring).

  3. The requirement • Need a pre-approved packaged design for biogas connections with suppliers on a call off contract to provide the built units to site • Key components: • Develop a fit for purpose cost-effective engineering specification for a packaged solution. • Develop a tender to source suppliers who can provide pre- approved packaged designs to meet the specification, which they can supply to site ready built. • Allow the concept to be future-proofed as ownership may not be with the GDN and regulatory requirements will change.

  4. To Bio Methane producer To Control Centre DB1Telemetry Unit Downstream remote monitoring option The scope of the basic package Gas produced by biomethane producer clean up plant (to include propane enrichment) Process Shut down valve Housing for the unit / component parts Instrumentation links Pressure Reduction Gas Analyser FWACV Gas Quality and supervisory system Fiscal Metering Gas Grid Odorant Injection Electrical transformer and electrical distribution system

  5. Approach to a packaged design Site specific design (G17) Telemetry Civil Site specific software Basic packaged approved design (G19) FWACV Software (approach) Instrumentation Electrical Mechanical User requirements specification / Functional Design / Software Design Spec, Test Procedures, Functional Blocks Company policies derived from Electricty at Work Regulations and British Standards TD/13 Industry Standards

  6. Work with Multi-disciplined engineering team – identify the sub systems and draw out the key requirements for each Build procurement strategy Issue full tender Engineering Integrity sign on Provide technical guidance and manage the input of technical experts to ensure the needs of the application are met Manage technical issues with suppliers input into design development Contract award Bid for first call off The journey to a packaged solution Build support for the concept

  7. Gas quality assessment Hazop with chosen supplier Select supplier Mini tender Supplier to produce site specific design amendments to basic package Unit built Install and commission How the call off arrangement will work New connection Call off Contract Supplier 1 Supplier 2 Supplier 3 Supplier 4 Complete telemetry / civil / pipework design

  9. The outcomes • Packaged designs which can operate over the following operating conditions: • Pressure • Max inlet of 7 bar and Min outlet of 75mb • Flow • 20m3/h - 2000m3/h • Size • Equal in scale to a shipping container

  10. The outcomes • Substantial cost saving • Lead times of 5-6 months (for supply to site) • Four suppliers are involved in the tender who can now be approached by DFOs/other GDNs should they wish to purchase a packaged unit. • Technica Ltd • Elster-Instromet • Orbital Gas Systems • Biogast/Future Energy Group Ltd • The work puts in place a platform for the industry to build from into the future.
