(4:30 p.m. EDT) -- There may be trouble ahead for MSC Cruises' MSC Opera, which lost power Saturday after experiencing problems with one of its electrical panels during a 10-night Baltic sailing out of Southampton.
According to a statement from the line, tugboats are en route to assist the 58,600-ton, 1,756-passenger ship, which has been diverted to the port of Nynamshamn in Sweden.
To those onboard the sailing, MSC is offering credits for free cruises of the same value, to be used by December 2012.
Although MSC has not released further details, several Cruise Critic members on the ship's roll call forum are sharing what they've heard.
Member 4nlalaland tells us that electricity and toilets aren't working onboard.
Meanwhile, on the MSC forum, boards member jaceyar says, "My friends are on this ship at the moment. Half the ship has no power, the loos are out of order and there is no hot food! They're doing just 8.5 knots."
MSC spokeswoman Julianne Carelli says there is no word yet on what this might mean for the ship's next sailing, which is scheduled to depart on Tuesday. We'll update this story accordingly as more information becomes available.
