This was the old Olympia Voyager; sister ship to the Olympia Explorer which just had problems in the Pacific.
FYI, there is also a Voyager of the Seas, a Royal Caribbean Ship. It is the namesake of the Humongous of the Seas Class.
Here is the report from Maritime Matters:
VOYAGER Powerless In Storm
February 14: VOYAGER (ex OLYMPIC VOYAGER, OLYMPIA VOYAGER) of Spain's Iberojet was battered by 30-foot (10 meter) waves in the western Mediterranean leaving the ship without power. With 480 mostly Spanish passengers and 296 crew onboard, the ship (sister ship to EXPLORER recently left powerless by a pacific storm, see January 27th news below) was sailing from Sardinia, on a voyage from Tunis to Barcelona, Spain. A French-led rescue operation was reportedly under way to reach the stricken ship, about 100km (60 miles) from Menorca. There were reports of minor injuries and the crew were battling to restore engine power, a liquefied gas tanker, GIMMI, was standing by after receiving the VOYAGER's distress call sent just after 0900 GMT February 14. A large wave smashed the bridge windows at about 0800 GMT damaging electronics causing the loss of power. The distress call said it was taking on water, coastguards reported. Two tugs were on their way to the scene and several aircraft have also been sent to the scene. Click here for Peter knego's tour of the ship as OLYMPIC VOYAGER

VOYAGER is expected at Cagliari, Sardinia, early on February 15. VOYAGER's messages are being relayed by the liquefied gas tanker, GIMMI, which was standing by.
