Deliverable D2.4 GEOTeCH Project. Report on the field trials of the augers and drill rig

Part of the work carried out in WP 2 of the GEOTeCH project involve field trials. These trials have the aim to select, design, test and evaluate components of the drill rig and the augers under development. We refer to the following: -Task 2.4. (M9-M14 Field trials of augers) -Task 2.6. (M4-M24 Drill rig design and prototyping). The results of the development and the testing were presented in deliverable 2.3. (M24 Drill rig and tooling operational and tested). In the current deliverable 2.4 relevant information from these field trials described above has been selected and is presented. Further field trials that are part of this report are the field trials carried out in preparation of the demo site installation (WP6) and the installation of the Tribano (IT) demo site in 2017. To compile the current report information from the following field experiments has been used: Field trials aimed at development of drill rig and components: - 2015 Amsterdam (NL): Initial field test with existing augers. - 2016 Emmeloord (NL): Field testing of augers and drill rig components. - 2016 Emmeloord (NL): Field testing of augers. - 2017 Emmeloord (NL): Field testing of heat exchanger installation. Field trials aimed at testing completed equipment and installation procedure: - 2017 Tribano (IT): Hiref demo site installation. - 2018 Leicester (UK): DMU demo site installation. - 2018 Amsterdam (NL): Groenholland demo site installation. Currently (month 32), the field trials at one of the demo sites (Tribano) is completed and the preparatory work for the demo sites in Leicester (UK) and Amsterdam (NL) has been completed and the sites await installation in the coming months. Both to Leicester and Amsterdam the pre demo site installation visits have been made and relevant information for the execution of the demo site installation is available. For the actual demo site installation and planning of the work we refer to WP6.
