Now we’re starting ! Proud to be alongside RTE this week as the construction of the HDD landfall begins on the coast of Brittany for the 700 MW Celtic interconnector.
This high-quality interconnection will link the south coast of Ireland to northern France, allowing the two countries to export / import electricity to and from each other whenever necessary, strengthening energy security. Supported by the Connecting Europe Facility (CEF) EU funding programme, this will be Ireland’s first interconnection with continental Europe.
The 3 parallel 440-metre-long landfalls (housing 2 x OD-355mm HDPE cable ducts and 1 x OD-250mm HDPE duct for fibre optics) will drill down 25m under the seabed, through extremely hard and abrasive granite, to ensure the cables are protected from tidal currents for years to come.
OPTIMUM specialist engineers have been supporting RTE on the Celtic interconnector project since 2018: conducting feasibility studies on potential coastal landfall sites, selecting the most appropriate site and trenchless technique, as well as providing technical expertise during the contractor selector phase. They will now accompany RTE throughout the operational phase of the landfall project.
Great to be part of another trenchless first ! Thanks to colleagues from CIDAC and Rte for the great teamwork so far.
