Packaging bio-methane connections for the futureDan Anderson CEng11th 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:
1. Develop a fit for purpose cost-effective engineering specification for a packaged solution.
2. 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.
3. Allow the concept to be future-proofed as ownership may not be with the GDN and regulatory requirements will change.

The journey to a packaged solution
Contract award
Bid for first call off
Build procurement strategyWork with Multi-disciplined engineering
team – identify the sub systems and draw out the key requirements for each
Engineering Integrity sign onIssue full tender
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
Build support for the concept

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.
