Objectives The objectives for the project for each WP include W. P 1 -Initial technology trials and development phase To evaluate and review technology, highlighting potential changes that would have to be implemented to ensure Mini-Mole is a realistic solution for LV applications Evaluate the potential benefits this technology could have and its application for DNOs W. P 2 - Onsite testing and review of existing methods and technology Successful product development and FAT / SAT testing To evaluate and quantify the volume of projects where this technology could be used. The development of a methodology for use, including evaluating and developing all safety and procedural requirements. W. P 3- Development of prototype units Development of a fit for use ‘Mini-Mole’ prototype unit W. P 4 - Integration into BaU To deliver the necessary business changes, documentation etc. required to facilitate ‘ Mini-Mole adoption prior to the end of this project. Upon completion of the work packages the following success criteria has been highlighted. The delivery of a viable alternative to traditional open cut trenching for LV cable applications. Quantified comparisons of current methods compared to using Mini-Mole.
Abstract Renewing and upgrading underground Low Voltage (LV) Cables and Service connections can be a costly and time consuming activity that is also disruptive to customers. The conventional DNO approach for this activity is to carry out open cut trenching to lay cables, whilst this is often the best solution in certain circumstances this approach can significantly increase costs and inconvenience to customers. For example, laying cables up driveways that consist of ornate or decorative paving leads to increased excavation and reinstatement costs, ties up resources from front line activities and causes a greater disruption to the customer. This civil challenge is likely to increase with smart meter enabling works and our social obligation to prioritise our vulnerable communities. Whilst the merits and risks associated with conventional open cut trenching are understood, there still remains a risk to field operators, pedestrians and customers in their proximity. Any alternative approaches that minimise this risk would deliver societal benefits worth pursuing. This project aims to develop a miniature / portable directional drill excavation unit which would allow it to be a less disruptive, cost effective safer solution to conventional open cut trenching for LV and Service cabling. SPEN has worked closely with Tracto Technik (TT), and one of our services and internal mains contractors, IQA Group, to create a ‘Mini-Mole’ that can be applied in limited space without complication. The R&D phase completed during the IFI 1417 Keyhole Trenchless Technologies project, will be manufactured into a full scale working prototype and extensively trialled to establish the benefit of the technique over conventional excavation methods for a variety of typical jobs. The project has been designed to create a safer, less disruptive and more resource efficient way for the business to carry out the repair and replacement of LV and Service cables.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
