International energy sharing is an important part of how today’s civilisations connect. In 2021, Magnum GSI approached Síor Consulting Ltd (Síor) to support a project to characterise ground surface deformation, along the existing route of a sub-surface High Voltage Direct Current (HVDC) cable installed within Irish highways infrastructure, part of a network connecting the UK and Ireland’s electrical grids.
Síor was commissioned to provide comprehensive hydrological, geotechnical, field-data collection, and information technology enriched geospatial consulting services through the deployment of our expert geoscientific team.
Síor’s responsibilities included:
- Review of HVDC installation as-built records and auxiliary data to map ground deformation risk profiles and inform inspection programme production.
- In field acquisition of survey data for a 41km stretch of the HVDC route, to inform office–based surface deformation analysis, including industry standard grading of surface deformations features as per Client defined scale.
- Production of a defect report and bespoke geoscientific geospatial mapping application.
Síor leveraged our combined geoscientific expertise to:
- Execute a comprehensive, data-driven, top-down, geospatial analysis to inform field-data acquisition activities.
- Prototype and develop a bespoke vehicle mounted video camera system.
- Comprehensive field-data collection combining point specific field-data with continuous 2.7k 60FPS video footage across the 41km stretch of the HDVC route.
- Prepare and manage geospatial data, culminating in the delivery of bespoke web apps to the Client.
