The initial conceptual designs need further development to ensure prototypes developed are suitable to all NTS CVSPs. With that in mind the project will consist of an initial feasibility and conceptual study to ascertain and mitigate existing project risks and ensure the prototypes undergo a formal process of safety assessment (FPSA) and a formal appraisal process to encompass all 37 CVSPs. A combination of a new probe design and construction techniques that take into account human factors have been identified by this project. Three prototype designs require evaluation under this proposal:
National Grid proposes that the prototypes are trialled at Churchover Multi Junction and Churchover Tee due to the site unique sample point requirements with all the proposed probe designs being required. This unique combination would also reduce construction costs with less mobilisation cost impact.
The project aims to deliver successfully a field demonstration of a combination of three new probe designs and construction techniques.
