Objectives The objective is to demonstrate the existing US developed CISBOT robotic technology and technique in the UK in order to test its practicality, effectiveness, current and future potential benefits as an initial step in support of the above Problem Statement. Successful insertion, operation and retrieval of the CISBOT robot in the chosen 18" CI LP gas main to inform an understanding of how this technique could be developed towards the overall objective.
Abstract Under RIIO the 3 tier approach allows a greater focus on risk and larger diameter ‘at risk’ iron pipes above the risk action threshold will only be subject to decommissioning if either condition or risk assessment or engineering judgement indicates this is justified. There is greater flexibility to allow the Gas Distribution Network (GDN) operators to exploit innovative solutions, where these are suitable and sufficient. It also ensures efficiency, environmental and reliability benefits associated with the programme are accounted for. Tier 2 pipes scoring above a risk-action threshold, set by the GDN operator, will be selected to receive appropriate attention over the period of the approved PSR regulation 13A programme. Appropriate attention means that Tier 2 pipes scoring above the risk-action threshold will either be decommissioned or, where a suitable and sufficient technique exists, assessed for continued use if found to be in good condition or remediated to allow for lifetime extension. GDNs are investigating various techniques to assess the condition of Cast Iron (CI) pipes including but not limited to coupon removal for localised metallurgy, DVST internal pipe inspections ( inner/outer wall corrosion, hairline cracks and induced strain) localised NDT (ultrasonic and magnetic flux for corrosion and pitting) and basic internal camera inspections. In addition there are a number of techniques to remediate and/or reduce pipe risk including permanent joint repairs (CISBOT) and semi structural linings. The overall objective for this initiative is to develop the capability to insert a robotic tool into a Tier 2/3 CI main to effect a permanent refurbishment of the asset. This project will allow the demonstration of the CISBOT robot to internally inject anaerobic lead yarn joint sealant into an 18" Cast Iron Low Pressure 200m section of live gas main.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
