Appeal for Vigilance Over Submarine Cables After Last Week's Bere Island Power Outage
ESB Networks has appealed for vigilance at sea in relation to submarine cables after a fishing vessel cut power to West Cork’s Bere Island last week.
ESB Networks restored power to some 280 affected islanders at 11 pm on Friday last, January 5th, some 31 hours after supplies were cut suddenly on January 4th.
The operator confirmed that the outage occurred “ as a result of a fishing vessel accidentally coming into contact with a cable running from Castletownbere to Bere island”.
It said that “repair efforts started immediately, which included a diver safely locating the damaged cable so ESB Networks crews could carry out the required restoration work”.
Power was restored to all impacted customers by 11pm on Friday night,it said, and it apologised to all those affected by the disruption.
There was considerable upset at the incident at a particularly difficult time of year and with islanders dependent on freezers to store food supplies.
An ESB Networks spokesman declined to confirm the cost of the repairs, or whether the fishing vessel had offered to contribute.
The non-governmental organisation Coastwtch said the incident illustrated the “damage large powerful fishing vessels can have on the fragile nature” of the seafloor.
It called on the State to recover costs from “those who caused the damage”, and said that “our heart goes out to families left without power in winter cold”.
Coastwatch co-ordinator Karin Dubsky questioned why the island was dependent on one power cable and said a Heritage Council study 20 years ago had flagged concerns about this.
Given that submarine cables are set to increase during offshore wind development, she said it was essential that the cable “isn’t just fixed but that the cause is determined and published with planned action” to avoid a recurrence.
The ESB said that “damage to our network by third parties can occur from time to time – generally on overhead and underground cables on land - and we run extensive public campaigns on staying safe and staying clear of our network”.
“This incident serves as a timely reminder that similar vigilance should be applied by those at sea to submarine cables”,it said.
