Three lifeboats were launched to help a P&O ferry that developed a “mechanical issue” – but power was eventually restored and it was able to continue its journey.
P&O tweeted that tugs from Larne and Belfast had been deployed to the vessel in the Irish Sea.
But shortly after the coastguard added: “The European Causeway has restored power and is now heading into Larne under its own power following an earlier mechanical failure.
“The various teams and vessels are continuing to support the vessel as they escort her to port.”
The Maritime and Coastguard Agency only released the ship, the European Causeway, from detention on 8 April after a reinspection.
