The aim of this project is to complete a Gap Analysis for full industry qualification requirements, complete independently certified testing, develop bends, crossings, and repair techniques.  The gap analysis and detailed research into current IGEM/API industry standards will be used to define independent testing to qualify the system beyond what has already been completed.  It has also been identified that key features are required to integrate the system more easily into current operating requirements.  This will include numerical modelling of the additional concept designs and methodology that will need to be developed.  Further work to realise the ongoing maintenance requirements and suitable integration to current regulatory and gas operator policies will be determined.  This will subsequently specify the design requirements for a large-scale trial.

Benefits

MASiP (Mobile Automated Spiral Intelligent Pipe) is an integrated approach to digital integrity monitoring, automated mobile pipe manufacture and flexible pipe structure.  Its structure, using HDPE as an internal liner with steel reinforcement, offers the possibility for pipeline operation to higher pressures compared to traditional unreinforced HDPE.  This modification makes it ideal for hydrogen transportation as it mitigates to the issues around hydrogen embrittlement of comparative steel pipelines. In addition, the use of digital fibre technology which forms part of the pipeline structure, provides real time 24/7 monitoring of the pipeline for integrity purposes.

As the SGN explores opportunities to build a green future and start working with hydrogen in blends up to 100%, this technology is perfectly poised to provide the monitoring needed to ensure the safe operation of the network. 

The project will provide unique and referenceable information for Network licensees and Industry on a potential new transmission pipeline materials option with 100% hydrogen. The learning gained from the project can be applied to Network Licensees and their network operations to facilitate safe transition to hydrogen from natural gas.
