MV Voyager has been delayed after suffering two generator failures while the ship was in port in County Donegal, Ireland.

Voyages of Discovery described the incident as “an unusual event” and said all 487 passengers and the 286 crew members remain on board.

The line said that at 2.45pm and 6.30pm yesterday, technical problems occurred leaving two of the ship’s four generators without power while in port in Killybegs. The nine-day Celtic Treasures cruise, which left Portsmouth on May 25, has been delayed while specialist engineers assess the problem.

Two generators are still working as normal and the ship has power, with all guest facilities operating as normal.

Captain Stuart Horner, director of fleet operators for parent company All Leisure Holidays, has flown to the ship to assist.

A spokeswoman for Voyages to Discovery said: “Additional shore excursions have been available to passengers during the extended stay in Killybegs and all passengers are being kept up to date with the situation.

“Voyages of Discovery has apologised to all passengers for these unusual and unforeseen circumstances which have arisen. 

“The safe continuation of the cruise and the safety of all guests and crew are the highest priority for Voyages of Discovery, which wishes to ensure that at least one of the affected generators is working fully before any decisions are made regarding the continuation of the cruise. An assessment of the generators is expected by the end of day.”
