The world’s first undersea cable repair between
Northern Ireland and Scotland was implemented on the Moyle Interconnector in 2014, by a team from ESB International and Mutual Energy. The undersea cable repair was carried out using innovative new technology using a habitat lowered to the sea bed, in which any cable can be fixed in situ on the sea floor.
In 2016 ESB
International repaired another undersea cable fault located about 2km off the
coast of Inis Mór, Ireland, restoring mains electricity supply to Inis Meáin and Inis
Oírr using this world-first in-house technology.
A
26-strong project team were based on Inis Mór for seven weeks.
The cable was energised from Inis Mór on Friday, and an intense period of
rigorous testing followed over the weekend.
