Fluid Filled Cables Assessment Project – Site Investigation

ESB Networks commissioned ESB Engineering & Major Projects (EMP) to undertake an environmental screening assessment of the fluid filled cables network to identify and assess leaks. Following the completion of the assessment, in agreement with the EPA and relevant authorities, a decision was made to begin intrusive assessments at agreed locations in order for an Environmental Consultant to complete the assessment.  Global Rail Services Ltd (GRSL) were appointed as main contractor and PSCS for the project for the 23No sites identified – encompassing both slit and 90° L trench excavations – at locations and sensitive receptors in agreement with the Environmental Consultant.  

Project activities included the safe exposure and logging of all services, ground conditions and make up therein.  No outages were available for the cables during the works, so all cables were treated as live.  Global Rail Services were responsible for the temporary works required to support the trench excavations.  Water samples were taken by the Environmental Consultant, which were recovered from rivers and canals close to each leak location.
