| Objectives | "Phase 1: A representative offline function test of the 18” BISEP® (horizontal orientation) will be performed at STATS HQ. The BISEP® test will consist of: Deploying and hydraulically activating the BISEP® in 100% inert gas. 26barg differential pressure will be applied. The BISEP® seals will be individually leak tested as per the usual BISEP® seal testing process. Coordinate with Innovation project team on matters arising from FPSA/HAZID/HAZOP Complete Factory Acceptance Testing observations: ITP and conformance / test certificates Vendor design documentation Roles and responsibilities Vendor operating instructions and functional test requirements Calibration certification Pre/post surface inspection reports to identify any pipe wall damage during functional testing Review pre / post inspection results (internal and external surface) Sealing capability Onsite checklist before commencement of field deploymentPhase 2: At Spadeadam, the testing and analysis will provide insight by: Testing with 100% Hydrogen of 1 x 18” BISEP® - this is a horizontal (parallel to ground) deployment Field deployment observations Witness single field deployment, observations, and report findings In advance of Online Deployment: Incorporate lessons learnt from Offline Trial Apply onsite checklist for Online Deployment Complete system checks Issue Online Deployment log, to record all activities and observations Commission and test tracking system During Online Deployment, complete field deployment log After Online Deployment, post-deployment review report, recommending future use of technology and procedure requirements" "The ongoing LTS Futures program of work (Element 3; Offsite Testing, Work Pack 1) includes hot tapping activities to be carried out in a flow loop rig at Spadeadam Research and Development facility which provides an opportunity to carry out the BISEP® deployment trial through one of the tees that will be installed. The loop rig at Spadeadam is installed above ground and will contain a section of 18” NB X52 pipe (spiral seam weld, 6.35 mm wall thickness) to which one grouted tee and two 18”x18” split welded tees will be installed under 100% hydrogen flowing conditions at a maximum flow of 7m/s. The working pressure of the rig is 20 barg. The BISEP® line stopping tool will be deployed through the 18”x18” split tee which will be installed with horizontal offtake, with the centreline of the offtake being at 0.5 m above ground level. It is assumed the drilling and BISEP® tools have enough ground clearance therefore no digging efforts have been added to this scope.The major advantage of undertaking the work at this time is that tee welding/hot tapping is already planned to be proven on the LTS Futures field trial being delivered. The addition of a BISEP® deployment is very small supplementary and complementary work, providing additional deliverables to the overall project scope. When successfully completed, a proven double block and bleed leak tight flow stopping technology will be available to the networks, which is an improvement on the technology largely currently in use by the networks, which is not leak tight." The objective is to demonstrate the operation and deployment of a BISEP® flow stopping tool, proving that the tool works to a satisfactory level as deemed by SGN. Therefore, and thereafter having a high integrity line stopping technology approved for use in 100% hydrogen. Following the completion of this project, sufficient evidence will have been collected to safely trial the BISEP tool on the LTS Futures live field trial. | |
| Abstract | Flow-stop tooling is regularly used for major projects and emergency works across the LTS and NTS gas networks. A pipe loop is being constructed in Spadeadam to assess the suitability of materials, procedures, and equipment with 100% hydrogen gas streams. The opportunity has presented itself to integrate testing (at Spadeadam) on the BISEP® tool delivering technical assurance prior to Grantham to Grangemouth live field trial on the LTS Future project. When successfully completed, a proven double block and bleed leak tight line stopping technology suitable for 100% hydrogen will be available to the UK Gas Networks and the earning gained from this project can be applied to Network Licensees and their operations to facilitate a safe transition to hydrogen from natural gas. | |
